i18n_column

Introduction

This extension provides the capabilities of storing and retrieving translations from a single database column. The translations are stored as a JSON object i.e. "en":"Home","de":"Zuhause".

The current and default locale are retrieved from the Rails Internationalization (I18n) API. Set the current locale on each request with i.e. I18n.locale = :de. If not set the default locale will be taken: I18n.default_locale. I18n.locale is used as the JSON key to store a translation i.e. "en":"Home".

i18n_column is tested with rails version 3.1.0

Installation

Gem

gem install i18n_column

Example

Migration

class CreateNodes < ActiveRecord::Migration def self.up create_table(:nodes) do |t| t.text(:name) end end

def self.down
 drop_table(:nodes)
end

end

Model

class Node < ActiveRecord::Base i18n_column(:name) end

Controller

class ApplicationController < ActionController::Base before_filter(:set_locale)

private

def set_locale
 I18n.locale = params[:locale]
end

end

Set the default locale in config/application.rb file

config.i18n.default_locale = :de

Console

I18n.locale = :en node = Node.create!(:name => 'Home') => "en":"Home" node.name => 'Home' I18n.locale = :de node.name = 'Zuhause' node.save! => "en":"Home","de":"Zuhause" node.name => 'Zuhause'

Known issues

  • Rails versions greater than 3.0.1: JSON hash instead of translation is displayed in form fields. Workaround:

f.text_field(:fname) instead of f.text_field(:name)
