A Rubocop wrapper that checks only added/modified code
View rubocop.rb
#!/usr/bin/env ruby
# A sneaky wrapper around Rubocop that allows you to run it only against
# the recent changes, as opposed to the whole project. It lets you
# enforce the style guide for new/modified code only, as opposed to
# having to restyle everything or adding cops incrementally. It relies
# on git to figure out which files to check.
# Here are some options you can pass in addition to the ones in rubocop:

Reverse polymorphic associations in Rails
View description.markdown

Polymorphic Associations reversed

It's pretty easy to do polymorphic associations in Rails: A Picture can belong to either a BlogPost or an Article. But what if you need the relationship the other way around? A Picture, a Text and a Video can belong to an Article, and that article can find all media by calling

This example shows how to create an ArticleElement join model that handles the polymorphic relationship. To add fields that are common to all polymorphic models, add fields to the join model.

Internationalization of a Rails App : conventions / guidelines / best practices

I have worked, and am currently working on internationalization of a Rails app. The apps require translating the ActiveRecord models. I have done some googling, but haven't really found any best practices / conventions / guidelines on how to think through this and what guidelines to follow.

I decided to create this document, to give myself a start and have it possibly help others. I am not an expert at any of this, and there may be things I am thinking incorrectly, but having it documented makes it easier to see the flaws and improve upon. If you have some ideas on additions, or think that somethings should change, get in touch.

Note: I use Globalize for model translations

  • I18n.locale controls the app wide locale. It refers to the particular localization version of the app. It defines how the app is localized to the user. It's scope is somewhat larger than the language/tran
