• a controller
• a helper

Views and assets are not defined because we think everybody wants to adapt the view in their page.

Installation

Add gem to your rails app in Gemfile :

gem 'language_engine'

Download gem librairies :

bundle install

Usage (with bootstrap plugin)

First you must set local in your application controller for example :

class ApplicationController < ActionController::Base
  protect_from_forgery
  before_filter :set_locale

  def set_locale
    I18n.locale = session[:language] || I18n.default_locale
  end

end  

And then you can use it inline :

 <ul class="nav navbar-nav navbar-right">
   <li class="<%= language_class('fr') %>"><%= link_to_language :fr %></li>
   <li class="<%= language_class('en') %>"><%= link_to_language :en %></li>
 </ul>

Or with dropdown :

<ul class="nav navbar-nav navbar-right">
  <li class="dropdown languages">
    <a href="#" class="dropdown-toggle" data-toggle="dropdown">
      <%= image_tag("language_engine/#{selected_language}_flag.png", { :'data-locale' => "#{selected_language}" } ) %><b class='caret'></b>
    </a>
    <ul class="dropdown-menu">
      <li><%= link_to_language :fr, { :class => language_class( :fr ) } %></li>
      <li><%= link_to_language :en, { :class => language_class( :en  ) } %></li>
    </ul>
