Rails plugin to translate your URLs and routing helpers on an clean way.
 Project Readme


Rails >= 3

The master branch supported some versions of Rails 3, though I've discontinued the development.

Two forks have been published as different gems and are the best alternatives I'm aware of:

Free Software is wonderful, isn't it? :)

Rails 2

You can find branches for Rails 2.1.x, 2.2.x and 2.3.x

This Rails plugin provides a simple way to translate your URLs to any number of languages, even on a fully working application.

It works fine with all kind of routing definitions, including RESTful and named routes. Your current code will remain untouched: your current routing code, helpers and links will be translated transparently - even in your tests. (Un)installing it is a very clean and simple process, so why don't you give it a chance? ;)


Add translate_routes to your Gemfile:

gem 'translate_routes'

And let bundle do the rest:

bundle install

Quick Start

  1. Let's imagine you have this routes.rb file:

    TranslateRoutesApp::Application.routes.draw do match 'contact' => 'contact#index' end

You can see the available routes with the rake routes task:

contact  /contact(.:format) {:controller=>"contact", :action=>"index"}
  1. Now write your translations on a standard YAML file (e.g: in /config/i18n-routes.yml), including all the locales and their translations pairs:


    you can leave empty locales, for example the default one

    es: contact: contacto

  2. Append this line in your routes.rb file to activate the translations specifying the path of the translations file:


  3. Execute rake routes to see the new routes:

    contact_es /es/contacto(.:format) {:controller=>"contact", :action=>"index"} contact_en /contact(.:format) {:controller=>"contact", :action=>"index"}

  4. Include this filter in your ApplicationController:

    before_filter :set_locale_from_url

Now your application recognizes the different routes and sets the I18n.locale value in your controllers, but what about the routes generation? As you can see on the previous rake routes execution, the contact_es_es_path and contact_en_us_path routing helpers have been generated and are available in your controllers and views. Additionally, a contact_path helper has been generated, which generates the routes according to the current request's locale. This way your link

This means that if you use named routes you don't need to modify your application links because the routing helpers are automatically adapted to the current locale.

  1. Hey, but what about my tests?

Of course, your functional and integration testing involves some requests. The plugin includes some code to add a default locale parameter so they can remain untouched. Append it to your test_helper and it will be applied.


You can find additional information in the translate_routes' wiki.
