I18n ActiveRecord backend

I18n::Backend::ActiveRecord

This repository contains the I18n ActiveRecord backend and support code that has been extracted from the I18n.

Installation

For Bundler put the following in your Gemfile:

  gem 'i18n-active_record',
      :git => 'git://github.com/svenfuchs/i18n-active_record.git',
      :require => 'i18n/active_record'

Next create a active record model named Translation with the Rails Generator.
Your migration should look like this:

  class CreateTranslations < ActiveRecord::Migration
    def self.up
      create_table :translations do |t|
        t.string :locale
        t.string :key
        t.text   :value
        t.text   :interpolations
        t.boolean :is_proc, :default => false

        t.timestamps
      end
    end

    def self.down
      drop_table :translations
    end
  end

With this translation model you will be able to manage your translation, and add new translations or languages through
it.

To load I18n::Backend::ActiveRecord into your Rails application, create a new file in config/initializers named locale.rb.

A simple configuration for your locale.rb could look like this:

  require 'i18n/backend/active_record'
  I18n.backend = I18n::Backend::ActiveRecord.new

A more adavanced example (Thanks Moritz), which uses YAML files and ActiveRecord for lookups:

  require 'i18n/backend/active_record'
  
  Translation  = I18n::Backend::ActiveRecord::Translation
  
  if Translation.table_exists?
    I18n.backend = I18n::Backend::ActiveRecord.new

    I18n::Backend::ActiveRecord.send(:include, I18n::Backend::Memoize)
    I18n::Backend::ActiveRecord.send(:include, I18n::Backend::Flatten)
    I18n::Backend::Simple.send(:include, I18n::Backend::Memoize)
    I18n::Backend::Simple.send(:include, I18n::Backend::Pluralization)

    I18n.backend = I18n::Backend::Chain.new(I18n::Backend::Simple.new, I18n.backend)
  end

Usage

You can now use I18n.t('Your String') to lookup translations in the database.
