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 Globalize for Rails was. Model translations in Globalize3 use default ActiveRecord features and do not limit any ActiveRecord functionality any more.
ActiveRecord > 3.0.0
To install Globalize3 with its default setup just use:
$ gem 'globalize3', :git => 'git://github.com/galetahub/globalize3.git'
Model translations allow you to translate your models’ attribute values. E.g.
class Post < ActiveRecord::Base translates :title, :text end
Allows you to translate the attributes :title and :text per locale:
I18n.locale = :en post.title # => Globalize3 rocks! I18n.locale = :he post.title # => גלובאלייז2 שולט! post.title_en # => Globalize3 rocks! post.title_he # => גלובאלייז2 שולט! post.title_en = "Globalize3 Super" post.title_he = "Globalize3 שולט"
Configuration available locales list (by default it returns I18n.available_locales):
Globalize.available_locales = [:en, :ru]
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.
Versioning with Globalize3
Globalize3 nicely integrates with vestal_versions:
As of writing (2010-08-05) the original vestal_versions respository has not been updated to be compatible with Rails 3 though. You can use this fork though. Globalize3’s Gemfile is currently set up accordingly.
Please also note that
update_attribute currently hides itself from dirty tracking in ActiveRecord >= 3.0.0.beta (which is considered a regression). That means that you currently need to use attribute writers or
update_attributes in order to track changes/versions for your models.
Also, please see the tests in test/globalize3/versioning_test.rb for some current gotchas.
Changes since Globalize2
- `translation_table_name` was renamed to `translations_table_name`
- `available_locales` has been removed. please use `translated_locales`
