ruby script/plugin install git://github.com/factore/has_foreign_language.git

Example
=================
First create your model:

script/generate model books title:string title_fr:string title_de:string author:string

Then specify which fields need to be internationalized in your model:

class Country < ActiveRecord::Base
  has_foreign_language :title
end

Now let’s create a book in the console and see how this works:

I18n.default_locale = "en" 
b = Book.new(:title => "Slaughterhouse Five", :title_fr => "Abattoir Cinq", :title_de => "Schlachthof Fünf")
b.title # Slaughterhouse Five
I18n.locale = "fr" 
b.title # Abattoir Cinq
I18n.locale = "de" 
b.title # Schlachthof Fünf

Calling title on the model returns the appropriate column depending on which locale we’re in. This also works when we change the attribute:

I18n.locale = "de" 
b.title = "Etwas Anderes" 
b # Book id: nil, title: "Slaughterhouse Five", title_fr: "Abattoir Cinq", title_de: "Etwas Anderes"

If you want to set or return the default language attribute while in a different locale, you can call it the way you would call any other. Assuming the default is “en”, you would run:

b.title_en # Slaughterhouse Five
b.title_en = "Something Else" # Book id: nil, title: "Something Else", title_fr: "Abattoir Cinq", title_de: "Etwas Anderes"
