CBA - Community Base Application

Pages and Postings can have Attachments % ryknehho

ryknehho — 2011-02-05T15:29:43+01:00

was having an issue trying to post comments to a blog posting, seems like there's an undefined method 'comments' for a Blog object. does anyone have the same problem? funnily, it seems to work fine on pages.

Multi-path CommentsController % nickendell

nickendell — 2011-02-01T07:42:09+01:00

Calculating the path where to redirect after :create, :update, :destroy was a bit of a hack but works fine now for any depth of nested resources.

Multi-path CommentsController % nickendell

nickendell — 2011-02-01T10:00:59+01:00

Just reviewed yesterdays work and pushed a clean version to github.

HUD for pictures % nickendell

nickendell — 2011-02-05T23:42:57+01:00

Just added HUD for user-avatars too.

Smells well again % Andreas

Andreas — 2011-02-08T13:15:16+01:00

Got a hiccup after adding file-size-validation for attachments. Because there was files larger 1MB yet.

When saving a user (which includes validation of embedded postings, which includes validation of embedded attachments) I got user.invalid. After removing attachments with large pictures through the console, everything was fine again.

Now I wonder, how I can test a case like this :)

Smells well again % Andreas

Andreas — 2011-02-08T17:50:43+01:00

Inspired by Ryan Bates' "Railscast #252":http://railscasts.com/episodes/252-metrics-metrics-metrics, I've tried "rails_best_practices":http://cba.iboard.cc/rails_best_practices_output.html - Really cool ;-)

Smells well again % nickendell

nickendell — 2011-02-08T01:49:17+01:00

TDD Rocks! It is such a good feeling when tests shows you errors which you would not recognize without testing :)

I missed, for some DelayedJob.enqueue-lines, to append the delay, but rake test shows them all before committing.

Endless page implemented % nickendell

nickendell — 2011-02-05T18:13:02+01:00

Still a matter of review, though endless_page now works with userlist and blogs too.

When code smells % nickendell

nickendell — 2011-02-07T01:18:02+01:00

BTW: I never drove CBA on a Windows-server and, may be, there are some more issues.

CBA is tested on Mac OS X 10.6 and Debian (Kernel: Linux dev 2.6.26-2-amd64).

I will appreciate mails concerning experience on other systems.

rake delayed_jobs:work in background % Andreas

Andreas — 2011-02-23T09:36:02+01:00

On Mac OS X you can do this through a LaunchDaemon. Documentation will follow.

Bundle update!!!! % Andreas

Andreas — 2011-02-09T19:23:17+01:00

Remove your Gemfile.lock before git pull ;-)

ooops - Signup was broken % nickendell

nickendell — 2011-02-06T10:27:47+01:00

Now I know what I've to do next week. How to test emails with rspec :)

Comments can be edited for 15 minutes % nickendell

nickendell — 2011-02-04T18:21:30+01:00

When an user posts a comment, the comment id and the timestamp will be stored in session[:comments] and then this values will be used in Ability.rb

Experimenting with Google-Custom-Search % Andreas

Andreas — 2011-03-01T13:43:45+01:00

Bad: If you're logged in and perform a search, clicking one of the results will sign you out. I have no idea how to fix this. Eventually by editing the google-javascript :(

thor deploy:production % nickendell

nickendell — 2011-02-05T12:08:25+01:00

To do this now and simple was highly inspired by a talk by Eishay Smith on Jan 14, 2011, found on "InfoQ":http://www.infoq.com/presentations/Continuous-Deployment-50-Times-a-Day

README % nickendell

nickendell — 2011-01-27T14:31:08+01:00

Andreas Altendorfer — 2011-01-27T07:53:57+01:00

CBA installation on a fresh debian box works. There are a lot of debian packages to install and some bash-settings to set, which I will document later.

README % alta

alta — 2011-01-28T07:23:11+01:00

"World Wide Education":http://wwedu.com/wwedu/startengl.html, the company I work for, will start using "CBA":http://cba.iboard.cc for new MicroApplications now.

Though CBA is a very young project, you can expect that CBA will be polished day by day to satisfy all needs for WWEDU when using CBA for enterprise purposes. This will guarantee that CBA will not die a silent death.

WWEDU uses a lot of OpenSource-stuff and this will be our give-back to the community.

README % Andreas Altendorfer

Andreas Altendorfer — 2011-01-27T07:55:56+01:00

I wrote an omniauth-strategie for campus.wwedu.com. so, wwedu-students may authenticate with their campus-account to our CBA-based micro-apps.

Markdown and Textile supported % Andreas

Andreas — 2011-02-16T05:29:58+01:00

Couldn't figure out why

== Header

sometimes work and sometimes don't.

Anyhow

Header

works in any case.

Comments reviewed once more % Andreas

Andreas — 2011-03-10T08:51:18+01:00

I have added new cucumber-features to test comments on pages and postings.

README % nickendell

nickendell — 2011-01-28T22:42:29+01:00

With this version of CBA you can define a file config/googleanalytics.head and put your javascript for Google-Analytics into this file. The file is then loaded in _production mode only.

New model Invitation % Andreas

Andreas — 2011-04-20T13:21:23+02:00

When I did bundle update I got an error "fetch': undefined methodspec' for nil:NilClass (NoMethodError)"

This could be solved with: a) locate your bundle-cache with command gem list -d bundler´ and then delete all files in the cache-directory. Finallybundle update´ works.

New model Invitation % Andreas

Andreas — 2011-04-23T14:00:40+02:00

The 'Invitation Function' is finished and working now.

README % Andreas

Andreas — 2011-04-23T19:32:41+02:00

Testing with SPORK added to cba:master

Translator Module % Andreas

Andreas — 2011-05-07T23:14:35+02:00

The view-code is a subject to be reviewed soon. I'm not happy with that. It's a quick and dirty solution with the intention not to touch the controller. I'll do some research to eliminate everything from the view.

The idea is: FormBuilder should be freedom-patched to handle translated fields for you. Once this will be done I will provide Translator as gem.

install.rb for easy installation % Andreas

Andreas — 2011-02-10T11:20:03+01:00

Will work on Un*x-Machines only ;-)

Tested on Mac OX 10.6, 10.7 and Debian with kernel 2.6.26-2-amd64

Upgraded to Rails 3.0.9 % Andreas

Andreas — 2011-06-21T10:39:24+02:00

oh - and without even recognize it - I implicitly upgraded to cucumber 1.0.0 - cool :D

Bring back SPORK with cucumber 1.0.0 % Andreas

Andreas — 2011-06-29T09:43:33+02:00

With this changes in spork/test_framework/cucumber.rb you may use the autotest thor task of CBA again:

thor application:run_autotests

Bring back SPORK with cucumber 1.0.0 % Andreas

Andreas — 2011-06-29T09:46:01+02:00

If you not sure where your GEMPATH is. Enter echo $GEM_PATH on the command-line ;-)

We Are Green Again % Andreas

Andreas — 2011-06-29T12:09:07+02:00

Obviously turning off warnings is no good thing. But I will wait for cucumber and spork to fix this problems ;-)

rdiscount replaced by redcarpet % Andreas

Andreas — 2011-06-29T16:40:49+02:00

puts "This is an example of CodeHighlighting"
puts "Use ```ruby to begin a code block and ``` to end it"

See We are green again for a larger code-highlighting example.

You may check out this commit to see how (easy) this change was done.

MongoDB 1.8 % Andreas

Andreas — 2011-07-02T07:17:28+02:00

Next I'll setup some replication across my servers. There is a good presentation of this on MongoDB's Website.

MongoDB 1.8 % Andreas

Andreas — 2011-07-02T08:44:36+02:00

Setting up the ReplicaSet was as simple as ABC too.

See this Gist how I did the setup.

Because my two nodes are located in two different data-centers, it took about 5 minutes to perform the initiate replication. During this time the application was not available.

YARD on Mac OS X Lion Preview % Andreas

CBA is running with Rails 3.1.0.rc4 on this Debian-box % Andreas

Andreas — 2011-07-10T00:43:59+02:00

Ok, I had to run

rake assets:clean       # Remove compiled assets
rake assets:precompile  # Compile all the assets named in config.assets.precompile

... and now the images are back again.

CBA is running with Rails 3.1.0.rc4 on this Debian-box % Andreas

Andreas — 2011-07-10T10:37:51+02:00

Cool, at the end it took me about 4 hours to port this application from Rails 3.0 to Rails 3.1.

Half the time I had to invest on Debian and the production mode. But fortunately my Debian box, running Apache2 and PhusionPassenger can handle 3.0 and 3.1 applications concurrently.

CBA - this application is running on CBA branch rails31
Altendorfer.at is running on CBA master branch.
rails.3.0.9 and rails.3.1.0.rc4 are both installed in the same rvm gemset which is loaded by Passenger.

PageComponent and PageTemplate sample-page

2011-05-02T16:31:14+02:00

PageComponent and PageTemplate sample-page

DEMO PAGE

This is an example how you may use PageTemplate and PageComponent in CBA.

For this Page we use Page: Body and components only template. This will not show the title of the page since we'll render it within this body (DEMO PAGE)

All attachments will be used within the follow components and doesn't need to be rendered by the page-template itself.

see Posting ...

Draft mode % Andreas

Andreas — 2011-07-10T22:58:22+02:00

If I look at this commit I'm not sure if I did this as simple as possible. I guess I'll should review this on a cooler day ;-)

Pages and Postings can have Attachments % nickendell

nickendell — 2011-02-03T07:10:05+01:00

I'm not sure - should attachments of type /image/ be rendered inline? Attachments are handled by Paperclip and if an attachment is an image the variants

 :popup  => "800x600=",
 :preview => "450x325=",
 :medium => "300x300>",
 :thumb  => "100x100>",
 :icon   => "64x64"

are processed by paperclip. So, it would be easy to display attachments in :show. But what's about the layout if there are many attachments?

Any suggestions?

Welcome Google+ % Andreas Altendorfer

Andreas Altendorfer — 2011-07-16T09:47:06+02:00

See Github-Commit how I did it.

OmniAuth / Twitter / SSL Error % Andreas Altendorfer

Andreas Altendorfer — 2011-07-23T09:25:00+02:00

BTW: I need to do this on my debian box only. On Mac OS X twitter-authententication works fine without this 'trick'.

Version Conflicts with Rails RC4 and Sprockets beta.12 % Andreas Altendorfer

Andreas Altendorfer — 2011-07-26T13:14:14+02:00

Tho, I didn't test it, I'm sure Rails rc5 and sprockets beta12 will work together ;-).

Mr. Birthday % Andreas Altendorfer

Andreas Altendorfer — 2011-09-01T07:03:41+02:00

Release Notes:

devise doesn't work with my bundle. So, this version runs with a fork of devise.
Autotests and thor application:run_autotests is back and works without issues on my macBook.

Testing with Jasmine % Andreas Altendorfer

Andreas Altendorfer — 2011-09-04T12:09:14+02:00

TODO: In this version it is necessary to precompile assets whenever you change a js-file. rake jasmine should handle fresh compiled versions of javascripts.

Using pow % reir

reir — 2011-09-07T11:17:33+02:00

I got a "Bad CPU type in executable" error due to my 32-bit Mac, so I had to install pow from source. See https://github.com/37signals/pow/wiki/Installation

Interpreter supports Youtube % Andreas Altendorfer

Andreas Altendorfer — 2011-09-09T14:35:07+02:00

At the moment this works only if the posting or page uses markdown as interpreter.

YouTube playlists will not be displayed on iPads, single videos works, tho

MongoDB Replica Set % Andreas Altendorfer

Andreas Altendorfer — 2011-09-13T18:32:35+02:00

Today, September 13, 2011, I changed the config from Replica Set to Master/Slave. Which makes more sense for me since I run two servers only.

New config/mongoid.yml

#....
production:
  host: localhost
  database: cba_production
  allow_read_secondary: true
  slaves:
    - host: s1.iboard.cc
    - port: 27017

On master: /etc/mongodb/mongodb.conf

MONGO_USER="mongod"
MONGO_OPTS="--master --dbpath /data/mongodb/ --rest --journal"

On slave: /etc/mongodb/mongodb.conf

MONGO_USER="mongod"
MONGO_OPTS="--slave --source edge.iboard.cc:27017 --dbpath /data/slave/ --rest --journal"

Bad bug drops pages unexpectedly % Andreas Altendorfer

Andreas Altendorfer — 2011-09-13T18:36:40+02:00

As I have to restore my database from backup, I decide to change from a ReplicaSet (of 2 servers) to Master/Slave configuration. See comment of posting

Tag-cloud implemented % Andreas Altendorfer

Andreas Altendorfer — 2011-10-07T07:54:25+02:00

Layout fixed - in tag.css.scss we defined divs for tag-weight 0 to weight 8. If a tag has a weight > 8 then no css-div was found.

To fix this I wrote a function named normalized_tags_with_weight in module ContentItem. With this little helper, all tag-weights will be between 0 and 8 by calculation used_weight = 8/max_weight*weight.

See this commit

Restrict postings to your individual groups % Andreas Altendorfer

Andreas Altendorfer — 2011-11-24T21:07:31+01:00

Please note When you save a posting with groups, CBA will save all users of all groups at this moment. If you remove a user from a group later, this user will still have access to the posting.

It's like sending an email to a defined group of your address book. Once the mail is sent, it is sent ;-)

Andreas Altendorfer — 2011-12-03T11:10:55+01:00

This issue inspired me to write this spec. And I think it should be done for any form, just to make sure the user will not have such an experience.

Everything is green again. You can use the latest version in branch master for production.

CSS & Layout cleaned up % Andreas Altendorfer

Andreas Altendorfer — 2011-09-12T16:25:04+02:00

See top of application.html.erb where the :resouce_action get prepared

<!DOCTYPE html>

<% if content_for? :resource_actions %>
   <% content_for :right_column_top do %>
     <div id='resource-actions'>
       <%= yield( :resource_actions) %>
     </div>
   <% end %>
<% end %>

And down the file you'll see where the right column got rendered.

<% if content_for?( :right_column) || content_for?(:right_column_top) %>
          <div id='right-column'>
            <% if content_for?(:right_column_top) %>
              <div id='right-column-top'>
                <%= yield(:right_column_top)    %>
              </div>
            <% end %>
            <div id='right-column-bottom'>
              <%= yield(:right_column) if content_for?(:right_column) %>

thor deploy:production

There is a new thor-task to deploy the app to the production server.

See config/application.yml[.sample] where you have to configure

production_server
production_user
production_path

Deploying steps:

Test your app thor application:test_all
Commit git commit -am '....'’
do thor deploy:production [--force]

The thor-task will then push your changes to origin/master and will call git pull; touch tmp/restart on your server.

Installing your ssh-key on the server will make it easy. Otherwise you have to enter your server’s password.

When code smells

2011-02-07T01:04:26+01:00

When code smells

Henry K. figured out that comments doesn’t work with Win32.
And I ran in some kind of strange troubles when I tried to send notification-mails for new comments.

Which means → that code smells!

Next week, I will review and eventually redesign the CommentsController and nesting of comments.

Though, notifications will be sent to the server-admin, whenever one is creating a new posting or comment. Obviously , in case of commenting a posting, the posting’s owner should be notified instead of the server-admin

Continuous loading reimplemented

2011-02-05T12:57:46+01:00

Continuous loading reimplemented

As in userbase, I’ve implemented ‘continues loading’ of postings.

You can configure the number of postings in application.yml: paginate_postings_per_page

If javascript is disabled, standard will-paginate will work. With javascript enabled there is a ‘load more’ button. Next, I will implement ‘automatic loading’ when scrolling to the botton of the page.

Bundle update!!!!

2011-02-09T19:10:29+01:00

Bundle update!!!!

If you’re using CBA before and you pull from GitHub, after February 9, 2011 you have to …

bundle update

Notes:

RedCloth — edge doesn’t work → version set to 4.2.2¹ in Gemfile
has_attached_file is obsolete with mongoid and was replaced by has_mongoid_attached_file

¹ I will check which version is the highest working, and will update this later. At the moment I found 4.2.2 working and did not care about any further.

Local Layouts are 'pull-safe' now

2011-02-11T08:20:16+01:00

Local Layouts are 'pull-safe' now

thor application:configure now supports local layouts.

You’ll be asked to enter a CSS- and layout-name.
Original application.css will be copied to yourname.css
Original application.html.erb will be copied to yourname.html.erb
New files will be appended to .gitignore

So, it’s save to git pull without losing your local layout.

Have fun!

User Role Logic Changed!

2011-02-11T17:58:04+01:00

User Role Logic Changed!

I’ve changed the User-Role-Logic from mask to integer

Before, user_roles_mask was a bitmask.
Now, it’s an integer.

Old user.role?([:admin,:maintainer]) returned true if the user was admin or maintainer. And, user.role?(:maintainer) returned true only if the user had :maintainer checked.

New user.role?(:maintainer) is true when the user is a maintainer or higher rated user.

ROLES = [:guest, :confirmed_user, :author, :moderator, :maintainer, :admin]

0=:guest and :guest only
1=:confirmed_user and :guest
2=:author and :confirmed_user, and :guest
….

This is much, much, much simpler in any aspect.

If you’ve a user-database already, please update thru the console.

ooops - Signup was broken

ooops - Signup was broken

I just recognized that I’ve configured a wrong default_host in my server-settings.

If you signed up to this server you’ve received an email with confirmation-instructions with a link to http://iboard.cc instead of http://cba.iboard.cc.

To fix this, just put the missing cba infront of the URL and it will work.

If you lost the confirmation-mail, you can request a new one → here

Restrict postings to your individual groups

Restrict postings to your individual groups

Latest version of CBA supports user groups and can restrict access to a posting to a defined user group.

Define your groups in your profile
Enter 'Recipients' when editing a posting

Only you and the members of the given groups will be able to access the posting.

Yes, I like Google's circle-idea ;-)

Tag-cloud implemented

Today I've added tags to Posting, using gem wilkerlucio / mongoid_taggable

Tags are implemented in ContentItem and can be used in Posting and Page.

Seems to work great. CSS for the tag-cloud needs some fixes, though.

Thank you Wilker Lúcio for your gem.

Comments reviewed once more

2011-03-08T19:00:40+01:00

Comments reviewed once more

Now there is a new view /comments for moderators, maintainers, and admins. This view lists all comments and offers a delete-button to due easy removing spam-entries.

I've done some more reviewing on the comment-model and added a 'root-resource' to access comments directly by their IDs without the context of their 'commendable'.

Also, there are some reviewed and new cucumber-features to check the comments behavior.

Welcome Google+

2011-07-16T09:34:58+02:00

Welcome Google+

Google+ is here and if I wouldn't need my Facebook account for the API-key for OmniAuth(entication) I would properly deactivate my Facebook account now ;-)

But ooops - CBA doesn't support Google-Logins. Time to add it!

Google Authentication was added to CBA (rails31 branch only)

There are some issues:

URLs to long for webrick and unicorn in development-mode
Adding other auth-services to an account with google-authentication works, though.
But adding GoogleAuth to an account with existing auth-services doesn't work.

(1) works fine in production-mode with PhusionPassanger

I have no idea how to solve (1) but I will investigate to solve (3)

Mac OS X 10.7 (Lion) and Dropbox

2011-03-01T10:09:07+01:00

Mac OS X 10.7 (Lion) and Dropbox

Living on the edge, I’ve installed Mac OS X 10.7 on my MacBookPro. Tho’ it’s a developer-version, it works fine. But one thing: Dropbox isn’t working.
Fortunately I found a fantastic hint at: Dropbox Forum
Thank you, Filip S.!

I’ve figured out a quick fix for this issue. Open Info.plist inside the application bundle, and change “Bundle Version” to 2.0 . Apparently Lion doesn’t allow applications with low bundle versions to run for some reason.

Works perfect on my MacBook. Thanks again.

No more spam-comments

2011-03-18T10:46:09+01:00

No more spam-comments

I just have added two flags to Blog and Page.

allow_comments, :boolean, default => true
allow_public_comments, :boolean, default => true

cba.iboard.cc suffers from spam-comments and now I can disallow comments for anonymous users.

There is a rake-task

rake cab:set_comments_allowed_defaults

which sets allow_comments: true but allow_public_comments: false

Smooth Scrolling

2011-12-04T10:19:00+01:00

Smooth Scrolling

The "Scroll To Top"-button of CBA now scrolls smoothly to the top of the page

It's simple with jQuery. See this commit

Get rid of prototype.js

2011-12-05T13:34:53+01:00

Get rid of prototype.js

Today (a bit late) CBA get rid of prototype.js by replacing the last bit of code using it by jcrop.

Thank's to Ryan Bates for his revised episode on Railscasts

Experimenting with Google-Custom-Search

2011-02-25T16:56:44+01:00

Experimenting with Google-Custom-Search

I just have created a Google Custom Search for my web sites.

If you want to use CBA with Google-Search enabled, follow this steps

Sign up your Google-Search-Account
Create a file config/google_site_search.html and paste the code you got from Google into it.

I'm still experimenting with Google Custom Search, and I will post my experiences here.

Notices

If using CBA in a productive environment, please make sure the following changes fits your needs otherwise change this settings if required.

robots.txt allows robot-access now

`rake cba:generate_sitemap`

There is a new rake-task to generate a sitemap.xml, which will be used by googlebot. To generate this file every eg 15 minutes you can define a cronjob in /etc/cron.d/cba

15 * * * * rails [ -x /srv/rails/app/bin/generate_sitemaps ] && /srv/rails/bin/generate_sitemaps

On my Debian-Box I've created the file /srv/rails/bin/generate_sitemaps. Change this in your crontab.

#!/bin/bash
source /srv/rails/.profile
export RAILS_ENV=production
cd /srv/rails/app/cba
rake cba:generate_sitemap

Don't forget to /etc/init.d/cron restart

Testing with Jasmine

2011-09-04T12:01:19+02:00

Testing with Jasmine

If you pull this CBA commit you'll find a version prepared to start with Jasmine.

This version doesn't fit my needs yet. It should be just a starter.

However, to try it, you have to do:

bundle
RAILS_ENV=test rake assets:clean
RAILS_ENV=test rake assets:precompile
RAILS_ENV=test rake jasmine

And then visit URL 0.0.0.0:8888

Branch rails31 merged into master

2011-08-26T15:51:01+02:00

Branch rails31 merged into master

CBA's branch rails31 is deprecated from now on. It is merged into master.

All tests are fixed and green.

If you pull from Github make sure you bundle update

And now it's time for a fine summer weekend at the pool.

Have Fun!

Mr. Birthday

2011-09-01T06:47:09+02:00

Mr. Birthday

Yesterday, Aug 31th, was my 47th birthday. I got a lot of love and nice presents. One of it was Rails 3.1 release

CBA's master moved to 3.1 release and is tested all green.

And there is a new feature: Maintainers can edit PageComponents inline. It's no longer necessary to edit an entire Page to make changes in a single PageComponent but you'll find an edit-link for each PageComponent. Using it will open just this component in the "overlay-div". (The edit-button is visible for users with role :maintainer)

Have Fun!

Using pow

2011-09-06T20:44:03+02:00

Using pow

I discovered POW and installed it on my macBook. Painless and simple.

Install POW like POW homepage guides you.
If you're using .rvm do: rvm --rvmrc --create 1.9.2-p180@r31 in your project's root directory.

ad2) Replace '1.9.2-p180@r31' by the rvm-environment you're using for development.

POW allows you to access your local development application at http://APPNAME.dev. So, get rid of http://0.0.0.0:3000 the easy way.

Using issues on github

2011-09-06T17:21:19+02:00

Using issues on github

I just started to use "Issues at Github" to track bugs and other issues of CBA.

Feel free to post your pains.

CSS & Layout cleaned up

2011-09-12T16:14:08+02:00

CSS & Layout cleaned up

After implementing CSS3-Buttons, I cleaned up CSS and application.html.erb a bit.

Admin-buttons are displayed at the upper right corner of the main-content-div and there is a div-tag for :right_column.

If you want to display buttons or other stuff from your views, use

Resource action buttons

:resource_actions will be displayed on the top of the right column.

  - content_for :resource_actions do
    %p= link_to( 'edit', edit_something_path(@something), :class => 'button edit'

Other stuff for the right column

Will be displayed below :resource_actions

  - content_for :right_column do
   %div
     whatever you want

RSpec and Selenium

2011-09-05T11:39:21+02:00

RSpec and Selenium

Latest version of CBA is prepared to use RSpec and test Javascripts.

See this Commit on Github

Note: Instead of using thor application:test_all you may run rake without any parameters now, to test everything, including the new Rspec tests.

rake

To run the specs only, do

rake spec:requests

I'd like to test the 'mouseover posting'-function which should popup a menu next the title of the posting. Unfortunately I ran into Capybara::NotSupportedByDriverError. No idea how to test this behavior yet :(

Example

In CBA any user with role :admin or :maintainer can edit PageComponents inline, when viewing a Page
This feature gets tested in spec/requests/edit_page_component_inline_spec.rb

Run the test

rake spec:requests

edit_page_component_inline_spec.rb:

require 'spec_helper'

describe "Test editing PageComponents (inline)" do

  describe "PageComponent Edit Button" do

    it "renders form in overlay and submits via ajax", :js => true do

      # Setup data
      cleanup_database
      create_default_userset
      my_page = create_page_with_component(
        :title => 'A page with one component',
        :body  => "The page's body",
        :is_draft => false,
        :page_component => { :title => 'First Component', :body => 'This is the origin component' })

      # Make sure we are on the expected page
      log_in_as "admin@iboard.cc", 'thisisnotsecret'
      visit page_path(my_page)
      page.should have_content("A page with one component")
      page.should have_content("This is the origin component")

      # Click the Edit link and edit the component
      page.all('a', :text => 'Edit').last.click
      fill_in "Title", :with => 'A modified component'
      fill_in "Body", :with => "This is a modified component"
      click_on "Update component"

      # Make sure modification is displayed
      page.should have_content("A modified component")
      page.should have_content("This is a modified component")

    end
  end

end

Configuration and Helpers

After you have installed RSpec with rake rspec:install you'll find this file:

spec/spec_helper.rb

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'capybara/rspec'

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
require 'spec_data_helper'

Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

RSpec.configure do |config|
  # == Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  # config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr
  config.mock_with :rspec

  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  #config.fixture_path = "#{::Rails.root}/spec/fixtures" # TURNED OF FOR MONGOID

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  #config.use_transactional_fixtures = true  # TURNED OF FOR MONGOID
  config.include SpecDataHelper
end

require 'spec_data_helper' and config.include SpecDataHelper ensures that you can access the helper-functions in your specs under spec/requests/*rb

SpecDataHelper defines helper functions you should use as shortcuts in your specs. e.g.

....
describe "Test editing PageComponents (inline)" do
  describe "PageComponent Edit Button" do
    it "renders form in overlay and submits via ajax", :js => true do
      cleanup_database             # Helper which drops any collections to make sure we start with an empty database
      create_default_userset      # Create a user for each role.
      log_in_as "admin@iboard.cc", 'thisisnotsecret' # visit the login-page and login with one of the users.
....

Interpreter supports Youtube

2011-09-08T22:52:43+02:00

Interpreter supports Youtube

CBA's interpreter supports two new tags you can use in Posting and Page

YOUTUBE : id

Embed a single Youtube-Video. id is something like Ynp-_pvoNAk

YOUTUBE_PLAYLIST : id

Embed a Youtube-Playlist. id is something like 79963DC001C316A6

Bad bug drops pages unexpectedly

2011-09-13T15:50:01+02:00

Bad bug drops pages unexpectedly

If you're using CBA in production, pull the latest version immediately!

A bad bug was not covered by tests blush and causes data-loss when editing a 'Blog'.

If you edit a blog and then update, unchecked pages was deleted, when they should be unlinked only.

This commit fixes this issue.

First, I wrote the Tests

And then I figured out the bad code:

# In model blog.rb
#BAD# @pages_before = self.pages.all
#BAD# self.pages = Page.criteria.for_ids(tokens.split(','))
#Better:
  @pages_before = self.pages.unscoped.all
  self.pages.nullify
  self.pages.push(Page.criteria.for_ids(tokens).all)

And I've added a dependency option to model blog.rb and page.rb:

#page.rb
  has_and_belongs_to_many :blogs, dependent: :nullify
#blog.rb
  has_and_belongs_to_many :pages, dependent: :nullify

RSS Feed is back again

2011-09-15T19:34:46+02:00

RSS Feed is back again

The feed.builder view did a 'concat' instead of output it's content as string. It was hard to write a test for this bug, because the content we expect is there, it's not formatted well, tho.

See this commit how I did the test and fix.

RailscastsPRO

2011-10-04T08:24:12+02:00

RailscastsPRO

Ryan Bates, famous for his Railscasts, announced RailscastsPRO yesterday.

The very first episode "Presenters" hits my needs perfectly. My Achilles' heel named 'Views' and this episode remembers me to move code from views to presenters.

I'm looking forward to see a lot of useful Railscasts with Railscast PRO.

Fulltext search in CBA

2011-08-08T23:25:21+02:00

Fulltext search in CBA

CBA implements fulltext_search to search in models Page and Posting.

Please run

rake data:generate_fulltext_indeces

after installing this version.

rake assets:precompile

may be necessary in production mode.

See this commit how I did it.

Sort using drag-n-drop

2011-08-11T01:38:09+02:00

Sort using drag-n-drop

Today I proudly announce my first public gem at Gemcutter.org

Using this gem you can setup an ordered list for drag-n-sort without a single line of Javascript-code.

In CBA this gem is used to sort menus.

Source is at Github

Using Presenters in CBA

2011-10-05T12:20:54+02:00

Using Presenters in CBA

Ryan Bates' first RailscastPRO is about 'Presenters'.

I knew about the existence of presenters but again, Ryan gave me the missing hint that I should use more presenters ;-)

See the picture (click it to enlarge) how many lines of code went from the view to the presenter, and how readable the view is now.

@ryan: "I like this kind of refactoring too ;-)"

To see all the changes take a look at this commit

OmniAuth / Twitter / SSL Error

2011-07-23T09:22:48+02:00

OmniAuth / Twitter / SSL Error

If OmniAuth and Twitter Login ends up in this error

OpenSSL::SSL::SSLError (SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed):

you can fix this in CBA's application-config. Add the following line to your file config/omniauth_settings.rb

  OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE

Sure, disabling SSL-Verification seems not to be the right solution and will open some security issues. This is a quick and dirty hack to bring up Twitter-Authentication again.

I will investigate to find a suitable solution with verification.

Important If you pull the latest version from branch rails31 you have to edit config/omniauth_settings.rb and add this line.

OMNIAUTH_CAPATH           = "/etc/ssl/certs"

YARD on Mac OS X Lion Preview

2011-07-02T10:45:03+02:00

YARD on Mac OS X Lion Preview

Last weeks, RDOC of CBA was provided with 'darkfish' because YARD didn't work on Mac OS X Lion preview 3.

Now I figured out how to enable YARD even on Lion.

Install the yard gem in Gemfile with this line in your Gemfile

gem "yard"

and bundle

Then edit yard.rb. With my rvm-environment it´s at ~/.rvm/ruby-1.9.2-p180@r309/gems/yard-0.7.2/lib/yard.rb:35. Change the path to fit your system.

# Workarround for Lion Preview: Force CONTINUATIONS_SUPPORTED to false
#
# Whether or not continuations are (properly) supported
#workarround# begin
#workarround# #  begin; require 'continuation'; rescue LoadError; end
#workarround# #  cc = callcc {|cc| cc }; cc.call if cc
#workarround# #  CONTINUATIONS_SUPPORTED = true
#workarround# #rescue Exception
  CONTINUATIONS_SUPPORTED = false
#workarround# #end

Then run:

  cd $RAILS_ROOT
  yard

CBA's documentation is much prettier again: online at my dav-server

CBA is running with Rails 3.1.0.rc4 on this Debian-box

2011-07-10T00:20:54+02:00

CBA is running with Rails 3.1.0.rc4 on this Debian-box

There are some minor issues, I couldn't fix for now but CBA is running on this Debian-box with Rails 3.1.

On Mac OS X all tests are green where on this Debian I need to use 2 extra gems

  gem 'therubyracer'
  gem 'execjs'

The icons for OmniAuth are not available in 'assets/....'. I'll try to fix this tomorrow. But I'm glad CBA is running here on 3.1.

Asset issues

I had to change paths to images in .js-files. See the following commits for details:

Fix path to close.gif and spinner.gif in .js
Fix path to spinner in js
Fix missing.png path
Rails3.1 on Debian and OS X
Move avatars to assets
Rails 3.1 on debian This seems to be a bug in Rails 3.1 when asset's file name contains numbers

SCSS

As you have noticed, the layout of CBA changed. This is because this version uses SCSS consequently. See assets/stylesheets/ for details.

The big advantage of the new layout is that there is only one single line where a color is defined as #ABCDEF and all other colors used are derived with invert,lighten,darken($something,value). So you can switch the entire layout from 'gray' to any color by just editing that single definition! I love SASS!

rdiscount replaced by redcarpet

2011-06-29T16:24:49+02:00

rdiscount replaced by redcarpet

Thank You! Ryan Bates for your latest RailsCast 'Markdown with redcarpet'. As always I couldn't resist to try this in my own project.

CBA now switched from rdiscount to redcarpet

New features are:

If a Posting or Page in CBA is set to be rendered with Markdown it now uses redcarpet
The choice of Textileis still available
Syntax highlighting was added for body in content_item.rb :: render_for_html
Comments are now rendered with the same "Engine" as it's commendable

Updating

sudo easy_install pygments
git pull git://github.com/iboard/CBA.git
bundle

On debian-boxes instead of easy_install you may use:

apt-get install python-pygments

Tested

On OSX Lion Preview 4 and Debian

MongoDB 1.8

2011-07-02T07:13:47+02:00

MongoDB 1.8

I just upgraded from Mongo 1.6 to Mongo 1.8 on this Debian-Box.

With absolutely no pain. Without reading one line of documentation. I did it as I thought it should work ... and it did.

Download from MongoDB
Untar
Stop Mongodb
Move the symbolic link from 1.6-path to the new 1.8-path
Start Mongodb again

That's how apps on linux should work. No installation at all. Copy files and use it. I love this.

All CBA-Tests are green and actually writing this post took me more time than upgrading mongodb.

We Are Green Again

2011-06-29T12:03:12+02:00

We Are Green Again

After updating to Rails 3.0.9, Cucumber 1.0.0 and Spork 0.9.0.rc8 some tests was broken.

This Commit fixes everything. But please notice this posting too. There are some things you have to do in the spork-gem, not in the CBA-source.

On my machine I faced some UTF-8-Warnings during cucumber-tests. To get rid of them you may use the following workaround in rack/utils.rb

module Rack
  # Rack::Utils contains a grab-bag of useful methods for writing web
  # applications adopted from all kinds of Ruby libraries.

  module Utils
    # Performs URI escaping so that you can construct proper
    # query strings faster.  Use this rather than the cgi.rb
    # version since it's faster.  (Stolen from Camping).
    def escape(s)
      original_verbosity = $VERBOSE                 #### SAVE STATE
      $VERBOSE = nil                                       #### TURN WARNINGS OFF
      rc = s.to_s.gsub(/([^ a-zA-Z0-9_.-]+)/n) {
        '%'+$1.unpack('H2'*bytesize($1)).join('%').upcase
      }.tr(' ', '+')
      $VERBOSE = original_verbosity                ##### BACK TO ORIGINAL SETTINGS
      rc
    end
    module_function :escape

    # Unescapes a URI escaped string. (Stolen from Camping).
    def unescape(s)
      original_verbosity = $VERBOSE               # SAME HERE
      $VERBOSE = nil
      rc = s.tr('+', ' ').gsub(/((?:%[0-9a-fA-F]{2})+)/n){
        [$1.delete('%')].pack('H*')
      }
      $VERBOSE = original_verbosity
      rc
    end

CBA branch for Rails 3.1

2011-06-25T22:14:19+02:00

CBA branch for Rails 3.1

I'm in the hospital because of an ear inflammation, getting antibiotics infusions. This is kinda boring and I had the idea to port CBA to Rails 3.1 instead of doing time. See -> Branch rails31

Thanks to @davidrice! Following his instructions it was a matter of about 30 minutes to get all tests green.

But fu* what shall I do tomorrow when even the cafeteria will be closed on Sunday :( Hopefully Formula-1 in Spain will make the day a bit exciting.

Twitter Box

2011-06-02T12:43:58+02:00

Twitter Box

The new feature will display a "Twitter-Box" on the right sidebar of the CBA-Homepage.

Howto

Grab your Twitter-Widget-code from the Twitter-Webpage.
Store this code in config/twitter.development.html and/or config/twitter.production.html

That's it.

Cucumber-feature

There are two new web-steps for cucumber to create and delete files (config/twitter.test.html) while running the features.

Note: When using autotesting with 'Spork' it is necessary to delete the file at the end of the feature. Otherwise 'Spork' will recognize the changed timestamp of the file and will start over and over again ;-)

SiteMenu

2011-06-10T13:22:28+02:00

SiteMenu

New model SiteMenu included today. (See commit)

SiteMenu is a tree-model, defined as

   :name => string # The label
   :target => string # The URL
   :role_needed => integer # Current User must have at least
   :position => integer # the position of this item in the current node
   :children

There is a SiteMenusHelper used in application-layout to display a sidebar for the currently selected root-menu.

SiteMenu Model and ViewHelpers are tested with Unit- and Cucumber-tests.

There is no interface to define the SiteMenu yet. Obviously an administration-interface is planed for the next future.

You may use a rake task to create a standard menu from your pages.

rake data:generate_standard_root_menu # Generate standard root_menu

Site Menu Controller

2011-06-19T18:18:31+02:00

Site Menu Controller

CBA now has a SiteMenuController to give admins the opportunity to edit the SiteMenu through the web-interface instead of editing the database on the console.

In today's release the views for editing site-menus are rather simple and rudimentary. Obviously this will be enhanced with a simpler drag-n-drop-sorting feature soon.

RTFC

Sitemenu sortable with drag and drop

2011-06-20T10:17:19+02:00

Sitemenu sortable with drag and drop

SiteMenus are now sortable with drag and drop using JQueryUI.sortable().

See Commit to find out how this was done.

Sorting SubItems in the tree still needs some fixes. After sorting Subitems it is necessary to reload the page in some cases. I'll fix this asap.

Upgraded to Rails 3.0.9

2011-06-21T09:48:48+02:00

Upgraded to Rails 3.0.9

I just upgraded from Rails 3.0.7 to Rails 3.0.9.

UTF-8-Encoding has to be forced in each file
Model.paginate has to be replaced by Model.all.paginate

See this commit to see all changes.

I did it like this:

rvm gemset create r309
rvm use 1.9.2@r309
gem install rails
bundle

Translator Module

2011-05-07T11:40:32+02:00

Translator Module

Today I've implemented a new module named "Translator".

With this Module you can define any Model to be translatable with just 2 lines of code in your model.rb

some_model.rb
......
include Translator
translate_fields [:field_one, :field_two, ....]

and then you can access the translation of any field with

@some_model.t(:de,:field_one)

this will give you the German translation if one exists or *de*OriginalValue if not.

To set the translated string of field_one, use

`@some_model.t(:de,:field_one, 'Eine Übersetzung')

There is a layout-helper-method which will support you to include the proper input fields in views.

translations_for_field( form_builder, field, field_type, *args, &block)

See attached files for more details.

New Feature - Pages shown with blogs

2011-05-03T14:30:37+02:00

New Feature - Pages shown with blogs

When editing a Blog you can assign existing Pages to this blog. Selected pages will then be displayed in the right side bar when rendering the blog.

The Idea

Items in the main-menu (define in vies/home/menus/....) can route to Pages and/or Blogs. Most blogs will need some static information for new users. This information can now be provided in the side bar.

CBA supports RSS-Feeds

2011-05-03T12:41:57+02:00

CBA supports RSS-Feeds

RSS-Feed is back

I've just re-added builder-code from userbase into this version of CBA.

/feed.atom will build a feed of 'Pages', 'Postings', and their 'Comments'

ViewContext-Issue

When calling posting.render_body(self) everything works fine and 'self' represents the Builder-view where model posting can render against.

But when calling page.render_body(self) self is something undefined. It's not 'nil' either it is any other thing?! At the moment there is a workaround in rss_feed.builder until I will be able to figure out what's going on here.

Start switching to HAML

2011-04-24T13:43:39+02:00

Start switching to HAML

User-views and invitation-view switched to HAML

All other html-views will follow step by step within the next weeks. Fortunately haml and erb can coexist in a project.

I think haml will force me to write cleaner views and it's much more readable than html with erb

Continuous testing with Spork

2011-04-23T02:26:02+02:00

Continuous testing with Spork

Spork, cucumber, drb.rb, Mac OS X Lion preview 2 (w update)

Slow testing is a reason to test less.

I live TDD for a year now and I learned to love it. But running the tests is some kind of boring. When searching for some extra speed I discovered spork through the BDDcast.

Great work! BTW

Spork works just as shown in the screencast with my unit-tests but fails with a Segementation fault in drb.rb when it comes to cucumber.

After dig into some logs I figured out that there was a SegFault when calling TCPServer and this smells to some leak with my Mac OS X Developer Preview 2.

Here the steps which leads to success on my workstation:

rvm uninstall 1.9.2
rvm install 1.9.2 (which should compile all native extensions with actual Lion-libraries)

But compiling ruby1.9.2 failed because of a wrong link to the libiconv.dynlib. To fix this ...

cd /usr/local/lib
sudo mv libiconv.2.dylib __libiconv2.dynlib (just to be on the save side)
sudo ln -s ln -s $rvm_path/usr/lib/libiconv.2.dylib ./
rvm install 1.9.2 -C --enable-shared (now works)
bundle install

And now everything works fine

AUTOFEATURE=true bundle exec spork cucumber
AUTOFEATURE=true bundle exec autotest

Start all at once with thor-task

In CBA's project path you can use thor application:run_autotests to start the spork-server and autotest. The shortest way to jump into continuos testing.
Check out thor task @ github to see single steps necessary to bring up spork in the terminal

rake delayed_jobs:work in background

2011-02-23T09:32:04+01:00

rake delayed_jobs:work in background

On Linux-Servers

Let `inittab` take care about

Add the following line to your file /etc/inittab

W1:23:respawn:/home/cba/bin/start_delayed_jobs_worker_cb

Create the script `start_delayed_jobs_worker_cba`

#!/bin/bash
su - YOUR_RUNTIME_USER -c "/home/cba/bin/delayed_jobs_worker_cba"

Make sure the file is executeable for root (chmod +x delayed_jobs_worker_cba)

The script will change the user YOUR_RUNTIME_USER - change this to your local user.

Finally create `delayed_jobs_worker_cba`

#!/bin/bash
cd $HOME/cba
RAILS_ENV=production rake delayed_jobs:work >> log/worker.log 2>&1

This will start the worker. (don't forget chmod +x)

init Q

init Q will start the script mentioned in inittab. Watch /etc/syslog to see if something went wrong.

Restart after code-changes

There is a thor-task you can use to restart the application and background-jobs

    thor deploy:restart [--worker_only]  # kill 'rake jobs:work' and 'touch tmp/restart.txt'

HUD for pictures

Cover-pictures of Blog and Posting can be displayed in a HUD now.
Also, any ‘Attachment’ of a posting of type /image/ can be displayed in a HUD.

In addition there is a new rake-task, named cba:reprocess_attachments to generate the :popup-size of the attachment. One may use this rake-task whenever a new style was added to a Paperclip-attachment

Rails Best Practices

2011-02-09T08:03:37+01:00

Rails Best Practices

Yesterday I discovered rails_best_practices, which was mentioned in Ryan Bates’ Railscast #252.

This gem is really cool! When I ran it against the actual code of CBA, it mentioned 29 ‘Errors’ and gave me detailed hints, where it would be worth to invest in some reviewing. And I did. Only two ‘errors’ left (see Attachment). For this two things, I see no need to change it. I definitively want a 2-level nesting of comments, and I see no (sense-full) chance to make the method in the user-controller even shorter.

From now on you will see the actual result for CBA → here

Pages and Postings can have Attachments

2011-02-03T06:58:16+01:00

Pages and Postings can have Attachments

Feb 3rd, 2011 | Models Page and Posting can have Attachments.

A new model 'Attachment' is embedded in 'Page' and 'Posting'.

TODO: In the actual version you have to insert a few lines to the model and the views. This should be moved to a lib-module, so 'has_attachments' should work in any model. And there should be 'partials' for the views.

Markdown and Textile supported

2011-02-14T09:15:54+01:00

Markdown and Textile supported

This version of CBA supports both markdown, and textile. Where markdown is default.

When updating to this version please follow this steps:

bundle
Set :textile to your existing Pages, and Postings

Update existing Pages and Postings, written with `:textile`

Use rails console to update:

Page.all.each do |p|

  p.interpreter=:textile

  p.save

end

And for the blog-postings

Blog.all.each do |b|
 b.postings.each do |p|
   p.interpreter=:textile
   p.save
 end
end

Endless page implemented

2011-02-05T14:00:02+01:00

Endless page implemented

On the root-page (where postings of blog ‘news’ are shown), there is a javascript now which will load the next page when the user scrolls to the end of the page.

See: public/javascripts/endless_page.js

The script detects the ‘EndOfPage-state’ and will click the ‘load more-button’ automatically. That’s all.

I did this as explained in Ryan Bates’ Railscast#114 but adapted it for “jQuery”.

New: rake delayed_jobs:delete_failed_jobs
Attachments validates the file size. See application.yml[.sample]
Attachments not saved in CommentsController:create → fixed
Attachments are attached to the ‘New Posting Notification’ – fixed (only the cover-pictures was attached before)

2011-02-04T18:19:58+01:00

Comments can be edited for 15 minutes

Even guest users can post comments on pages and postings and may edit them within 15 minutes. This should give you a chance to correct typos or mistakes.

After 15 minutes it should not be possible to edit comments because this will confuse other users when reading a thread which changes over time.

CBA now supports Blogs and Postings

Jan 30th, 2011 | CBA now supports Blogs and Postings

If a blog is named News it’s postings will be displayed on the Home-page. You can configure the number of postings in application.yml.

Only registered users can create postings.

Next todo: Of course, it should be possible to comment a posting.

Choose what you need

template.rb will ask you which of the resources (Pages, Blogs) you will use in your application.

Note: template.rb is not finished yet and will not work with this version! There will be a posting as soon as installation from template.rb will work.

Added GeoLocation for user-model

2011-10-12T18:11:17+02:00

Added GeoLocation for user-model

I was at #mongomunic on monday and one of the most impressive talks was by @coffepunk about GeoIndexing with MongoDB.

So, I couldn't resist to try this within CBA.

As Jörgen mentioned, it was really easy ;-) See this commit.

The bigger hack was to deal with the Google-API.

Attention If you're running a CBA-Server and you pull this version, don't forget to add the following line to your file config/omniauth_settings.rb

GOOGLE_PLACE_API_KEY      = 'not_used_for_v3'

The value doesn't matter, tho, but the constant will be accessed in application.html.erb to support Google API v2 too.

For now you have to enter longitude and latitude as values. Anyhow, the api to use Google-places will follow soon. Once this is done the user can enter his address or any other name of a place.

@coffeepunk: You're right! It's fun and easy! :D

Reverse GeoIndexing

2011-10-14T11:52:32+02:00

Reverse GeoIndexing

In the last version a user has to know the coordinates of her location to enter the value when editing her profile.

Now I've added reverse-lookup and you can enter a place or address. Google-API will do the lookup and if an entry was found, it will update the preview-map.

See this commit how this was done.

On document-load: Initialize the map
On keyUp in the location-field: Search by coordinates and update map
On keyUp in field address: Search by address. If Google-API returns one place only, the zoom-level is set to 16 (close-up) otherwise it is set to 16-number of places found.

Have fun!

Interpreter supports Google-maps

2011-10-18T19:11:11+02:00

Interpreter supports Google-maps

The interpreter of today's version of CBA supports Google-map-links within the text/body of 'Posting', 'Page', and 'PageComponent'

Example by place-name

The RailsConf 2010 and 2011 was at the Convention Center at 1 Pratt Street, Baltimore, MD, USA and it was great!

To generate a link like above, enter "name of the place", anywhere in your posting or page.

The RailsConf 2010 and 2011 was at the Convention Center in [ PLACE:1 Pratt Street, Baltimore, MD, USA ] and it and was great!

You may enter any 'Place' or 'Address' known by the Google-Places-API, like Technisches Museum, Wien.

If you'll use a PLACE-link, as an author of a posting or a page, please notice: if your place-name doesn't match any place or will find a ton of places, the map will stay blank or will take very long to load. If not sure, use maps.google.com to find a proper name.

Example by location

To generate a link to a place defined by latitude,longitude, enter [LOCATION:longitude,latitude], like here ...

I had a funny afternoon-walk to The Frank Zappa Monument, which is located at 39.286481,-76.566949

I had a funny afternoon-walk to The Frank Zappa Monument which is located at [ LOCATION:39.286481,-76.566949 ]

Google's satellite-picture and street-view seems to be outdated. No Zappa-Monument there :/ but I've attached the picture I took there. It was the birthday of the library, so it happened that Frank is wearing a birthday-hat :D

Have fun!

User-groups/Friends implemented

2011-10-21T10:48:13+02:00

User-groups/Friends implemented

I've added a new model 'UserGroup' which is embedded in User.

A user can define several UserGroups and can add other users to this groups.

At the moment this groups will not be used, just maintained. In one of the next updates you can use your user groups to grant access to your postings and pages.

The plan: When writing a post you can address this post to individual users or several groups of your choice. Only this addressee will be able to read the post then. If you do not provide a list of recipients, the post will be public.

See this commit how UserGroup is implemented.

As mentioned, the functionality to use this groups will follow soon.

Fix interpreter and add support for videos

2011-11-30T12:10:57+01:00

Fix interpreter and add support for videos

See this commit. This feature will allow rendering attachments of postings and pages.

1: When creating or editing your Page or Posting you can add Attachments

2: Use

  ATTACHMENT:n

anywhere in the body of your posting or page. Where n is the number of the attachment (starting at 1)

Depending on the content-type of the attachment one of the following methods will be used

linkto _filename, path #default
image_tag attachment.file.url(:medium)
video_tag attachment.file.url

Here is an example with ATTACHMENT:n with n=1:

Source of this video is unknown. It's awesome, tho! This attachment is of type video/quicktime and has the extension .mov. It will play in Safari and other modern browsers but it will not play within Safari on the iPhone and iPad.

Let's try a .3gp-video, the same way, using ATTACHMENT:n (with n=2)

This will rendered on iPads just as with standard Safari.
On iPhones, a click on the video will open the quicktime-player on the phone in fullscreen mode.

And a third example

Testing dropdown-selects

2011-12-03T11:00:40+01:00

Testing dropdown-selects

There is a risk in forms with drop down selects.

Scenario

You have a field which can be edited by selecting from a drop down
This drop down has no option for "nil-value"

Sh%t$ will happen

When such a form gets rendered, the first option of the drop down is selected if the current value of the field is not in the list of options. Saving this form without changing anything will still update the field behind the drop down. That's definitely not what the user will expect here.

spec

with this spec you can make sure this will not happen for a form with any attribute.

  it "opening for edit and save without making changes should not change anything (Bugfix: PT#21801945)" do
    blog = Blog.create(title: 'Restricted users', is_draft: false, is_template: false, user_role: 1)
    _saved_attributes = blog.attributes.dup
    log_in_as "admin@iboard.cc", "thisisnotsecret"
    visit edit_blog_path(blog)
    click_button "Update Blog"
    blog.reload
    _changed_attributes = blog.attributes
    _changed_attributes.delete('updated_at')
    _changed_attributes.each do |key, value|
      unless _saved_attributes[key].to_s.eql?( value.to_s )
        puts "ATTRIBUTE CHANGED: #{key.to_s} was '#{_saved_attributes[key]}' and changed to '#{value}'"
      end
      assert _saved_attributes[key].to_s.eql?( value.to_s ), "Attribute should not change "
    end
  end

Left sidebar per controller

2011-11-29T14:41:15+01:00

Left sidebar per controller

This commit implements the following feature:

As default behavior, CBA renders the left sidebar with a search-box, the current sub menu, and the tag-cloud.

New with the changes in application.html.erb CBA looks for a partial named _sidebar.haml|.html|.html.erb in the directory app/views/CURRENT_CONTROLLER/. If this file exist, it will be rendered as a partial instead of the default stuff.

For example:

If you want a special left side-bar while the user is using the BlogsController, just create the partial app/views/blogs/_sidebar_left.haml.

Searchbox and Tag-cloud

If you like to place the search-box and/or tag-cloud onto your individual sidebar, use:

or with HAML

  #searchbox= render 'search/form'

  #tagcloud= tag_cloud

Standard menue

You still will be able to render the default menu in your sidebar. Here is the HAML-example

  %ul
     = build_submenu_box(current_root(self)) do |entry|
        %li= entry

MongoID Chaining More any_of Criterias % Andreas Altendorfer

Andreas Altendorfer — 2011-12-31T15:36:20+01:00

If you deal with the idea to implements stuff like this ... wait a bit if it's possible.
MongoID will support new options when it's come to merge selectors, as Durran told me in response to my entry at Github.

The Mongoid API in 3.0 will support it, I'll have the docs updated when it's released to show you how, but in short it will allow you to define the merge strategy when chaining criteria, either intersection, union, or override.

IMPORTANT! Migrate your production-data

2012-01-02T09:02:09+01:00

IMPORTANT! Migrate your production-data

Before you can use the latest version of CBA on your production-servers, do the following migration (through the console)

RAILS_ENV=production rails console

Posting.unscoped.all.each do |p|
  if p.recipient_ids.nil? || p.recipient_ids == []
    p.recipient_ids = nil
    p.save
    p.recipient_ids = []
    p.save
  end
end

Why? recipient_ids defaults to [] but old data will be stored without recipient_ids. Scopes of the latest commit will not find such entries.

MongoID Chaining More any_of Criterias

2011-12-31T12:46:02+01:00

MongoID Chaining More any_of Criterias

What we have

In CBA we have module ContentItem and two models using it: Page and Posting

A ContentItem has the following "flags"

is_draft (boolean)
publish_at (nil or Time)
expire_at (nil or Time)

and an array of recipients (User-Ids) this ContentItem is addressed to. If this Array is empty, the item is supposed to be public visible. Otherwise it should be displayed to the given users only.

The Problem

When I implemented scopes I ran into some trouble using any_of

The scopes should be:

Posting.online .... only postings between publish_at and expire_at
Posting.published .. Doesn't have is_draft == true
Posting.addressedto (_user) .. Postings where user is in the list of recipients or recipient_ids is empty.

For online and addressed_to we need to use any_of

Addressed To and Published - scope

scope :addressed_to, ->(user_id) { where.any_of( 
                                              {:recipient_ids => nil}, 
                                              {:recipient_ids => [] },
                                              {:recipient_ids => [user_id] },
                                              {:user_id => user_id} 

                                          ) 
                                    }

Online-scope

scope :published, -> { where(is_draft: false) }
scope :online, -> { any_of(
                 {:publish_at=>nil,:expire_at=>nil},
                 {:publish_at.lte=>Time.now(),:expire_at=>nil},
                 {:publish_at.lte=>Time.now(),:expire_at.gt=>Time.now()},
                 {:publish_at => nil, :expire_at.gt=>Time.now()}
                )}

What happens

STEP 1 - START WITH ALL POSTINGS OF BLOG(self)

_postings = self.postings.unscoped

The criteria is OK

#BSON::ObjectId('4e1fc176f9110517c4000002')},
  options:  {},
  class:    Posting,
  embedded: false>

STEP 2 - RESTRICT TO PUBLIC POSTS OR POSTS ADDRESSED TO OR OWNED BY USER

_postings = _postings.addressed_to(_user.id)

Here the first any_of comes in

#BSON::ObjectId('4e1fc176f9110517c4000002'), 
      "$or"    =>[ {:recipient_ids=>nil}, 
                   {:recipient_ids=>[]}, 
                   {:recipient_ids=>[BSON::ObjectId('4ea7dafdf9110540a3000013')]}, 
                   {:user_id=>BSON::ObjectId('4ea7dafdf9110540a3000013')}
                 ]
    },
  options:  {},
  class:    Posting,
  embedded: false>

The criteria is still ok. The $or-selector is added.

STEP 3 - RESTRICT TO !draft AND WITHIN GIVEN DATE-RANGE

_postings = _postings.published.online

Now we got

#BSON::ObjectId('4e1fc176f9110517c4000002'), 
      :is_draft =>false, 
      "$or"     =>[
                    {:publish_at=>nil, :expire_at=>nil},

    },
  options:  {},
  class:    Posting,
  embedded: false>

OK, the date-range was added with $or BUT where the $or for recipient_ids is gone??!

The Solution

When I did some research on this I found this issue on MongoID

It makes clear that there can be one $or-key only for a given selector and my approach to combine two $or-selectors will not work :(

A Possible Workaround Without Using Chained any_of Selectors

This works for CBA. I hope I'll find a better solution for this, tho.

It fetches all posting-ids for each selector and then combines this id-arrays with & which will result in a new array containing only ids which are present in all arrays. At the end we can provide a Mongo-Criteria using postings.for_ids

def postings_for_user_and_mode(_user,_draft_mode=false)

  # if no user is given then return only public and online postings
  unless _user
    _online =  self.postings.online.only(:id).map(&:id)
    _public =  self.postings.publics.only(:id).map(&:id) 
    _published=self.postings.published.only(:id).map(&:id) 
    return self.postings.for_ids(_online & _public & _published)
  end


  # if user is moderator and in draft_mode then return all postings
  if _draft_mode && _user.role?(:moderator)
    return self.postings.all
  end


  # The mongo-driver is not able to combine two any_of ($or) as "and"
  #
  # model.any_of( :f1 => '1', :f2 => '2').any_of( :d1 => 'x', :d2 => 'y')
  # is not equal to
  #    select * from model where ( f1 = 1 OR f2 = 2) AND ( d1 = x OR d2 = y ) 
  # but it will act as
  #    select * from model where ( f1 = 1 OR f2 = 2 OR d1 = x OR d2 = y )
  #
  # Posting scopes using any_of are:
  #   * addressed_to(user_id)
  #   * online

  # public or addressed to _user
  _addressed_ids = self.postings.addressed_to(_user.id).only(:id).map(&:id)

  # in range of publish_at and enxpire_at
  _online_ids = self.postings.online.only(:id).map(&:id)

  unless _user.role?(:moderator)
    unless _draft_mode
      _visible_ids = _online_ids & self.postings.published.only(:id).map(&:id) & _addressed_ids
    else
      _visible_ids = _addressed_ids
    end
  else
    _visible_ids = _online_ids & self.postings.published.only(:id).map(&:id)
  end

  self.postings.for_ids( _visible_ids )
end

pre-released and expired postings are marked with badges

pre-released and expired postings are marked with badges

Now it's easy to identify postings which will not be online at this time.

See 'postings.css.scss' where you can define the css-classes for .online, .expired, and .prerelease

Chart-drawing with HighChart

After trying a lot of different JS-libs for chart-drawing, I made my decision: HighChart for my Darts Log Application (See Example).

HighChart is free for non-commercial applications and there is a fine Railscast how to use it in a Rails-Application.

Fragment caching for Tag-cloud % Andreas Altendorfer

Fragment caching for Tag-cloud

2012-01-19T02:29:52+01:00

Fragment caching for Tag-cloud

I've added a fragment-cache for the tag-cloud.

Collecting the tag-cloud had a performance issue since we're now checking for expired, prerelease, draft, recipient_ids of any item.

To fix this, the tag-cloud will be cached for 20 minutes now.

+: It's fast again
-: The tag-cloud will not update within this time.

TODO: Expire caches when a posting or page will be created or updated instead of doing this every 20 minutes.

Get rid of a bad idea

2011-12-11T21:26:06+01:00

Get rid of a bad idea

To be honest, implementing a method render_for_html in the model (ContentItem) was a bad idea. With this commit we got rid of this.

Thank's to TDD I can guarantee that everything is working well. Some CSS-issues will be fixed soon, though.

In this new version, CBA's models, based on ContentItem are rendered using a new class Interpreter and presenters.

Do not use this version in production. It's a first preview of this new structure and CSS-fixes will follow later this week.

TDD RULEZ!

New controller to submit user notifications

2011-10-09T10:19:28+02:00

New controller to submit user notifications

There is a new controller for admins and maintainers to send user notifications to all or a list of users.

UserNotifications will be displayed on top of page when a user is logged in. A user can hide notifications and can list all notification with menu "(i)"

The route is /user_notifications/new. Add a menu for it in 'Menus' or run rake-task

rake data:generate_standard_root_menu

Attantion! This rake task deletes your current menu-records. Use it only for new installations. Otherwise add the new menu item manually.

When composing a new notification:

Enter recipients (supports autocomplete by email or name)
or leave the recipients field blank to send the message to all users.

Notifications are embedded in model User. When creating a new notification it is stored in admin's user-document and will be copied to all recipients after create.

Upgraded to Rails 3.1.1 and MongoID 2.3.1

2011-10-11T18:17:44+02:00

Upgraded to Rails 3.1.1 and MongoID 2.3.1

Latest version of CBA works with Rails 3.1.1 and the new MongoID-version 2.3.1

Both works fine and faster. I had to create a new gemset from scratch on my debian-box, tho.

Notable: Using the latest MongoID, I could (had to) remove a workaround in Blog.rb.

All tests are green. See this commit for details on changes.

Upgrading your gemset

I was faced the following error when I did bundle update

uninitialized constant Psych::Syck (NameError)

To fix this, I had to do

rvm install 1.9.2-p290
rvm use 1.9.2-p290
rvm gemset create r311
rvm use 1.9.2-p290@r311
gem install bundler
gem install rails -v 3.1.1
bundle update

Because of the newly created gemset, I had to install passenger for this gemset too.

gem install passenger
rvmsudo passenger-install-apache2-module

And then copy the new passenger-config to /etc/apache/mods-enabled/passenger.conf

A final apachectl restart brought up the new version.

It's so cool to live on the cutting edge :D

HTML5 File Upload Progress Bar

2011-08-19T07:17:55+02:00

HTML5 File Upload Progress Bar

I wrote a new gem to display a progress bar while uploading files. It works works with Rails 3.1 and HTML5 browsers.

It is an early prototype. Don't expect too much. But I think it's very useful and I will review and cleanup/finish it soon.

CBA with Ruby 1.9.3-preview and Rails 3.1.0.rc5

2011-08-05T14:06:51+02:00

CBA with Ruby 1.9.3-preview and Rails 3.1.0.rc5

If you wanna try CBA on the edge, there is a Github branch preview online.

The steps to try this without any risk:

rvm install 1.9.3-preview1
rvm use 1.9.3-preview1
gem create gemset rails3.1-preview
rvm use 1.9.3-preview1@rails3.1-preview
cd ......CBA/
git checkout preview
bundle install
thor application:test_all

Depending on your system you may face some troubles when gem installs native extension. On Lion I had to recompile everything from scratch, and I had to skip the TKLib for ruby1.9.3, where on an old macMini with SnowLeopard it worked as listed above.

Have fun!

Upgraded to Rails 3.1.0.rc5

2011-07-28T14:07:25+02:00

Upgraded to Rails 3.1.0.rc5

After pulling the latest version from github, please do

Version Conflicts with Rails RC4 and Sprockets beta.12

2011-07-26T13:09:18+02:00

Version Conflicts with Rails RC4 and Sprockets beta.12

I'm using rails.3.1.0.rc4 and sprockets is not mentioned in my Gemfile.
When I did bundle update today, sprockets.2.0.0.beta.12 was installed
and compiling assets was broken, at least in development-mode
Adding the following line for sprockets to my Gemfile and bundle update fixed it.

gem "rails", "3.1.0.rc4"
gem "sprockets", "2.0.0.beta.10"

MongoDB Replica Set

2011-07-26T07:02:19+02:00

MongoDB Replica Set

Tonight cba.iboard.cc and altendorfer.at was down because the connection between primary and slave died.

MongoDB switched to secondary-mode on the server where this application is running while primary was not reachable.

In this state every request was answered with a 500 and the log tells me Mongo::OperationFailure (not master and slaveok=false):

The new setup in config/mongoid.yml now take care of this:

development:
  host: localhost
  database: cba_development

test:
  host: localhost
  database: cba_test

production:
  host: localhost
  database: cba_production
  allow_read_secondary: true
  replica_set:
    - uri: mongo://localhost:27018
    - uri: mongo://s1.iboard.cc:27018

Draft mode

2011-07-10T22:53:53+02:00

Draft mode

ContentItems (Page, Blog, and Posting) got a new field is_draft. If it's set to true only Authors will see this entry.

Note If you pull this version when you already have content items, then you have to perform the following commands on your data (using console)

for resource in [Page,Blog,Posting]
  resource.unscoped.all.each do |r|
    r.is_draft = false
    r.save
  end
end

Moving forward

2011-07-09T08:39:58+02:00

Moving forward

CBA master branch will switch to Rails 3.1 soon.

At the moment, 'master' is for Rails 3.0.9. The new branch 'rails31' is fully functional and all tests are green. Only install.rb doesn't know about the new assets-directory.

Next week I will adapt install.rb and then I will move the 3.0-version to a new branch (which will be left unsupported) and merge rails31 to back to master.

I love haml, sasl, coffee script and I will not stick around in an "old world" ;-) Rails 3.1 RC4 is stable and I guess ready for production.

Bring back SPORK with cucumber 1.0.0

2011-06-29T09:40:44+02:00

Bring back SPORK with cucumber 1.0.0

Since cucumber 1.0.0 spork doesn't work.

As mentioned in spork's issue #122 you can fix this problem by commenting some lines in YOUR GEM PATH/spork/test_framework/cucumber.rb

    def preload
      require 'cucumber'
      #if ::Cucumber::VERSION >= '0.9.0'
        # nothing to do nowadays
      #else
        preload_legacy_cucumbers
      #end
      super
    end

    def run_tests(argv, stderr, stdout)
      #if ::Cucumber::VERSION >= '0.9.0'
      #  ::Cucumber::Cli::Main.new(argv, stdout, stderr).execute!
      #else
        ::Cucumber::Cli::Main.new(argv, stdout, stderr).execute!(@step_mother)
      #end
    end

Attention when pulling latest version

2011-06-24T19:07:33+02:00

Attention when pulling latest version

The latest version on github includes a default scope for pages.

default_scope  where(is_template:false)

After pull it won't work for existing documents! You have to do

Page.unscoped.all.each do |p|
  p.is_template = false
  p.save
end

in the console.

ATTENTION - Comment Associations Redesigned

2011-03-04T18:05:46+01:00

ATTENTION - Comment Associations Redesigned

Comments was embedded in Page::comments and Blog::Posting::comments. The difference in nested level causes some troubles with this code.

Comment is a top-level-collection now

Comments of postings are referenced as

Page
  references_many :comments, :inverse_of => :commendable

and Postings are referenced as

Posting
    references_many :comments, :inverse_of => :commendable

And Comment has:

Comment
   referenced_in :commendable, :inverse_of => :comments, :polymorphic => true

Migrate your data

A bit strange! We're using MongoID but we still need migrations. And this seems to be more difficult than generate migration in ActiveRecordWorld?!

checkout branch 'old_comments'
run `rake cab:export_comments > /tmp/some_temp_file.json
checkout branch 'master'
run `cat /tmp/some_temp_file.json | rake cab:import_old_comments

New feature 'PageTemplate', and 'PageComponent'

2011-05-02T16:11:40+02:00

New feature 'PageTemplate', and 'PageComponent'

New in CBA - Simple Layout for Page and PageComponent

Page Components

A page in CBA consists of a :name, a :body, :attachments, and a :cover_picture. Now there is a collection :page_components too. A Page can embed as many page_components as you like. With no 'Layout' components are rendered below the body and attachments, and before comments.

When editing a Page you'll find 'Add Component' at the end of the form.

As the Page itself, any PageComponent can use a 'PageTemplate'

Page Template

Also new in CBA are Page(html)Templates. A PageTemplate has a name, a css_class, and a html_template. Where html_template is HTML-code which can embed any of the following keywords (in CAPITAL letters):

T I T L E ... will be replaced by the title of the page.
B U T T O N S ... will be replaced by Edit-, and Delete-buttons
C O V E R P I C T U R E ... will be replaced with an image_tag to the cover-picture of the page
B O D Y .... will be replaced by the B O D Y of the page.
C O M P O N E N T S ... replaced by all :page_components of the page
C O M P O N E N T[n] ... render component 'n'
C O M M E N T S ... replaced by comments and new comment-form
A T T A C H M E N T S .... render all attachments.
A T T A C H M E N T[n] .. link to Attachment 'n' of the page. Render inline if it's of type 'image'

Page Template Names

Please notice that PageComponents doesn't render the entire set of keywords (yet). To identify templates of PageComponents please name all templates "Component: ....."

You can create a default set of templates by

rake db:seed

Please notice the CSS-Tags which will be printed on $stdout when running this rake-task and make sure you have this tags in your stylesheet.
If you fork CBA after May 2nd, 2011 you will have this css-tags otherwise, or if you doesn't use application.css but your own css-file, please copy and paste this styles to your file.

Rails 3.2 is here!

The Ruby On Rails Blog announced the official release of version 3.2.

I couldn't resist from trying it. Fazit: Faaaast! Some gems I use not available for 3.2, tho. I'm looking forward to move CBA to 3.2 within some weeks.

Great job done by the RailsCore-Team and contributers. Thank You!

CBA - Community Base Application Template

At Github

Issues

Known issues maintained in Github-Issues

Quickstart

I highly recommend to use RVM!

Requirements for CBA:

A running MongoDB Server
A rvm gemset for Rails Rails 3.1.0

   curl -o install_cba.rb \
   https://raw.github.com/iboard/CBA/master/install.rb
   ruby install_cba.rb

This will install a fully functional web-application, with user-authentication (incl. omniAuth) on a document oriented, non-SQL, MongoDB/MongoID database. Just ready to be extended by your 'real' application code. As a benefit, CBA will offer two MVCs Page and Blog.

Note: Project's README should be identical to README.textile on Github -- I try hard to keep both versions in synchronized state, but check out the Github-version too.

CBA is forked from Rails3-Mongoid-Devise by fortuity, extended by Andi Altendorfer with

OmniAuth
Paperclip
CanCan
jQuery

CBA's own implementations

Models/MVC
- User
- Blog
- Posting
- Page
Features:
- Comments and Attachments for all models
- i18n enabled (en/de)
- installation.rb (See: Posting)
- Configuration in application.yml

Installation

See: Posting 'installation.rb'
CBA is in heavy development age, so please read CBA Blog from bottom to top. There are some latest news, not mentioned in this README.

Delayed Jobs

There is a rake-task to start the background jobs

  rake delayed_jobs:work

Unfortunatley DelayedJobs by 'tobi' doesn't work with MongoId.
So I did this my own way. To define new background-workers follow this steps:

1 Define a worker in app/workers (See new_sign_up_notifier.rb)
2 Enqueue new Jobs like shown in app/model/user.rb, method async_notify_on_creation (Source)

Resource 'Page'

Since nearly any website needs some kind of 'semi-static pages' and we need some kind of object to test the application, there is a resource Page with the following features

Consists of a title and a body
The body is rendered with RedCloth
The MongoId of /page/MONGO_ID in the browser-address will be replaced by /p/title_of_the_page with JS.

Testing with Spork

To run autotests you have to start the spork-server and then run autotest command

AUTOFEATURE=true bundle exec spark
AUTOFEATURE=true bundle exec autotest

To run your unit-tests using spork do

bundle exec spork TestUnit --port 8988
testdrb -I test test/unit/*rb

Start all at once with thor-task

You can use thor application:run_autotests to start the spork-server and autotest. The shortest way to jump into continuos testing

Layout and Templates

Edit application.css or 'your_name_given_at_install'.css
Edit views/layout/application.html or views/layout/'your_name_given_at_install'.html.erb
