Ruby5
Daniel Willemse do 29 jul 10
This week, when looking for an answer to one of my ruby issues, I stumbled across
an awesome website called ruby5.envylabs.com
Where you can listen to, and get updated on the latest ruby news in a couple of minutes.
You can subscribe to it via iTunes, and it also has an RSS-feed.
Pretty easy to keep updated now, as you can just listen to it while doing your daily ruby business.
Check it out!

Suppress Rails logging
Dax Huiberts wo 28 jul 10
When Rails applications get rather complex the amount of log statements can get rather big in development mode. It is not uncommon to get hundreds of lines of SQL log statements.
This creates a problem when you try to insert your own log statements. With all the noise it gets pretty difficult to filter out your own log statements. One way is to prefix your statements with “>>>>>>>>>>” or “==” (or many more of those). If that doesn’t even help there is alway the ‘tail -f log/development.log | grep =’. This is not a very workable sollution either. In this case you also miss your request information. Like how long the request takes or what the request parameters are.
I’ve been using the following code snippet for a week now and it really meets my need:
# config/initializers/suppress_rails_logging.rb # suppress active record sql logging class ActiveRecord::ConnectionAdapters::AbstractAdapter def log_info(*args); end end # suppress 'rendered partial ...' logging module ActionView::RenderablePartial def render(view, local_assigns = {}) super end end
This snippet of code suppresses the ActiveRecord SQL logging statements and the ActionView ‘rendered partial …’ logging statements. It makes my logs useable again and I still don’t lose my request information logging statements.
Try it out and see for yourself wether this works for you. Please leave a comment for any feedback you have.

Rails gem: Localized pluralization with i18n
Paul Engel di 27 jul 10
As you are working on an internalization Rails application, you are maybe using Globalize2 along with I18n to translate models (e.g. categories). The end-user is probably able to manage the translations in different locales such as Dutch, German, French, Spanish and so forth.
>> I18n.locale => :en >> (c = Category.first).name => "birthday" >> I18n.locale = :nl => :nl >> c.name => "verjaardag" >> I18n.locale = :fr => :fr >> c.name => "anniversaire"
Sometimes you want to display the translation in pluralized form. For instance:
>> I18n.locale => :en >> "Found " + c.name.pluralize => "Found birthdays"
A solution to accomplish this is to translate both singular and plural form:
>> I18n.locale => :nl >> I18n.t("found").capitalize + " " + c.name_pluralized => "Gevonden verjaardagen"
There are some cons though:
- you have to translate in singular AND plural form
- you have to use two columns (
nameandname_pluralized)
That’s some sort of redundancy as we want to keep things DRY: only translate in singular form and pluralize the translation. Fortunately, there is a Rails gem that does just that:
Rich-pluralization is a E9s module which pluralizes words with inflection rules of the current locale. You can compare it with the ActiveSupport::Inflector, except that the inflections do not influence the Rails pluralization (which is used for methods as tableize and classify).
Looking at our previous example, this is what the implementation can look like:
>> I18n.locale => :nl >> I18n.t("found").capitalize + " " + c.name.pl => "Gevonden verjaardagen"
And of course, you can pluralize static strings:
>> I18n.locale => :nl >> "Fiets".pl => "Fietsen" >> "MUSEUM".pl => "MUSEA"
Please note: the letter casing stays preserved(!)
All in all, using Rich-pluralization provides you to only translate in singular form and call .pl for the pluralized translation. Now isn’t that a DRY implementation?
At the moment, Rich-pluralization is shipped with Dutch inflections. It covers 86% of the 54977 words provided by INL. This will increase as the developers are working hard on improving the inflections. Also, you can also add inflections for other locales.
Please visit the Github project page if you are interested for more information.

CSS3 Pie: Making your life as a webdesigner a little bit easier
Johan Vermeulen vr 23 jul 10
We all know how it’s like to create beautiful websites, slice it and see it work in all the major browser, except for Internet Explorer.
Enter CSS3 Pie: CSS decorations for IE. Jason Johnston of 327creative.com wrote a CSS library which can be used in Internet Explorer with the IE behaviors capability. This library partially adds CSS3 support to IE6/7/8.
Example:
Normally: plays nicely in FF/Safari/Chrome
#myElement { background: #EEE; padding: 2em; -moz-border-radius: 1em; -webkit-border-radius: 1em; border-radius: 1em; }
For IE: Rounded borders \o/
#myElement { ... behavior: url(PIE.htc); }
PIE currently has full or partial support for the following CSS3 features:
- border-radius
- box-shadow
- border-image
- multiple background images
- linear-gradient as background image

jQuery Hashchange
Stephan Kaag do 22 jul 10
Nowadays web apps do heavily depend on Ajax requests (think GMail).
As we all know: by using Ajax request we lose the possibility to bookmark specific pages and the possibility to use the back and forward buttons in our browsers because the url doesn’t change.
Ban Alman wrote javascript solution for this problem. Enter jquery-hashchange. This jQuery plugin enables very basic bookmarkable #hash history via a cross-browser HTML5 window.onhashchange event.
Version 1.3 was recently released. Check it out at github.

Roy van der Meij zo 18 jul 10
I just found out about UKI, a javascript framework.
Basically: you stop writing html code,
and start writing interfaces.
Now I’m not sure if I’m going to use this in production.
But it has been fun playing around with it.
Check it out and tell me what you think about it.

Upgrading to rails 3.0
Daniel Willemse vr 16 jul 10
Seeing as upgrading your <3.0 rails app isn’t just changing the rails version in your env.rb I started looking for an easier way.
Scouring through the internet, I stumbled across this little gem + guide: rails-upgrade-automating-a-portion-of-the-rails-3
by Jeremy McAnally. I haven’t found time to play with it much, but I’ll definitely look into it more this weekend.
He also wrote a book railsupgradehandbook that gives you the basic tips / tricks to upgrade your app to a rails 3.0 app.

I didn’t check my RSS reader for a while, which resulted in a long list of unread posts. This is a summary collection of interesting tidbits.
bullet 2.0.0.beta.3 gem released
At @holderhq Bullet alongside New Relic saved us loads of time speeding up some database intensive apps. Especially when ActiveRecord magic and ActiveRecord extensions make your development log look like a wizards spell book describing how to fetch green goblins with red hats from middle earth.

Gregory Brown’s Ruby Mendicant University idea is taking off. I think the idea is great and I’m closely following the progess.

I didn’t have the time to check it out yet. But it looks like this’ll certainly help javascript development.

Bundler 1.0 without system gems
Wijnand Wiersma do 15 jul 10
The last time I talked about bundler I showed how to use the 0.9 series and everything will be in it’s own bundler bubble.
However, starting from bundler 1.0 systems gems will be prefered with sudo installs and this might be not what you want.
Some perfectly valid reasons might be:
- You are deploying to webservers as an unprivileged user and don’t want to sudo
- You don’t want the existing apps to break because incompatible gems are being installed
I was looking at the bundler source code for a solution and found out it was actually quite easy to solve.
Just add a path after “bundle install” !
So when installing an application on a production server you can let capistrano (or whatever you use for deployments)
run the following command: bundle install ~/.bundle
Inside the application a config file will be created and respected.
This configuration file consists of the following content:
--- BUNDLE_DISABLE_SHARED_GEMS: "1" BUNDLE_PATH: /Users/wijnandwiersma/.bundle
As long as this configuration exists the system gems will not be touched.
Until recently I wasn’t a big fan of bundler but because of this presentation I fully understand all decisions that made bundler the way it is. I think you should watch it too. I think I will convert some rails 2.3 apps in the near future.
