has_multilingual_attributes

• This gem is a very simple monkey patch into the ActiveRecord class.
• It gives you a locale-aware model attribute, provided you appropriately named your columns in db.
• The convention for the field naming is: [field name] + '_' + [locale], e.g. 'description_en'.
• Only supports 2 locales (:fr and :en) for now.

Suppose you want a locale-aware description field for your ActiveRecord model Item. With this:

class Item < ActiveRecord::Base
  # that implies you have those 2 database fields in your items table:
  # 'description_fr' and 'description_en'
  has_multilingual_attributes :description
end

You'll get a virtual attribute description which content will vary according to the current locale:

> item = Item.new :description_fr => 'desc fr', :description_en => 'desc en'
=> #<Item id: nil, description_fr: "desc fr", description_en: "desc en">

> I18n.locale = :fr
=> :fr

> item.description
=> "desc fr"

> I18n.locale = :en
=> :en

> item.description
=> "desc en"

• Read supported locales from config.
