Globalize3

Globalize3 is the successor of Globalize for Rails. Globalize is targeted at ActiveRecord 3.

It is compatible with and builds on the new I18n api in Ruby on Rails. and adds model translations to ActiveRecord.

Globalize3 is much more lightweight and compatible than its predecessor was. Model translations in Globalize3 use default ActiveRecord features and do not limit any ActiveRecord functionality any more.

Requirements

ActiveRecord > 3.0.0.rc
I18n

Installation

To install Globalize3 with its default setup just use:


$ gem install globalize3

Model translations

Model translations allow you to translate your models’ attribute values. E.g.


class Post < ActiveRecord::Base
  translates :title, :text
end

Allows you to values for the attributes :title and :text per locale:


I18n.locale = :en
post.title # => Globalize3 rocks!

I18n.locale = :he
post.title # => גלובאלייז2 שולט!

In order to make this work, you’ll need to add the appropriate translation tables. Globalize3 comes with a handy helper method to help you do this. It’s called create_translation_table!. Here’s an example:


class CreatePosts < ActiveRecord::Migration
  def self.up
    create_table :posts do |t|
      t.timestamps
    end
    Post.create_translation_table! :title => :string, :text => :text
  end
  def self.down
    drop_table :posts
    Post.drop_translation_table!
  end
end

Note that the ActiveRecord model Post must already exist and have a translates directive listing the translated fields.

Alternative Solutions

  • Veger’s fork – uses default AR schema for the default locale, delegates to the translations table for other locales only
  • TranslatableColumns – have multiple languages of the same attribute in a model (Iain Hecker)
  • localized_record – allows records to have localized attributes without any modifications to the database (Glenn Powell)
  • model_translations – Minimal implementation of Globalize2 style model translations (Jan Andersson)
