ActiveRecord Globalize Build Status Code Climate Test Coverage Inline docs

Rails I18n library for ActiveRecord model/data translation using PostgreSQL's hstore datatype. It provides an interface inspired by hstore_translate but without the need for data migrations (zero down time solution for large set of data).


Add this line to your application's Gemfile:

gem 'activerecord_globalize'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activerecord_globalize


You'll need to define an hstore column for each of your translated attributes, using the suffix "_translations":

class CreatePosts < ActiveRecord::Migration
  def up
    create_table :posts do |t|
      t.column :title_translations, 'hstore'
      t.column :body_translations,  'hstore'
  def down
    drop_table :posts

Model translations allow you to translate your models' attribute values.

class Post < ActiveRecord::Base
  translates :title, :body

Allows you to translate the attributes :title and :body per locale:

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

I18n.locale = :he
post.title # => אתר זה טוב
