title: Force one specific language across the whole Ruby on Rails application
body: <p>I need to configure my Ruby on Rails app to use one single language (English).</p>
  
  <p>By default, Rails translates all form validation messages to the local language.</p>
  
  <p>I have tried adding the folowing to the file <code>config/application.rb</code>: </p>
  
  <pre><code>config.i18n.default_locale = :en
  config.i18n.available_locales = [:en]
  </code></pre>
  
  <p>When I run my form (which is generated with a form generator), the validation messages appear in my local language (Spanish) instead of English.</p>
  
  <p>Any Ideas?</p>
