title: How to search for controllers in multiple directories?
body: <p>I created a very simple plugin system in my Rails application. These plugins can bring along their own views and controllers in their subfolder.</p>
  
  <p>Thus, when searching for controllers, I want Rails to look in one of these directories:</p>
  
  <ul>
  <li><code>app/controllers</code></li>
  <li><code>plugins/plugin1/controllers</code></li>
  <li><code>plugins/plugin2/controllers</code></li>
  </ul>
  
  <p>I added those plugin directories to my autoload_path in <code>application.rb</code>, but that had no effect.</p>
