title: application.html.haml not rendered
body: <p>I am using rails version 3.2.12 and was using .erb templates for my view.</p>
  
  <p>Now I want to start using haml templates.</p>
  
  <p>I added haml and haml-rails to the gem file and installed the bundle.</p>
  
  <pre><code>Using haml (4.0.0) 
  Installing haml-rails (0.4) 
  </code></pre>
  
  <p>I have made a mock-up application.html.haml</p>
  
  <pre><code>!!! 5
  %html
    %head
      %title Rotten Potatoes!
      = stylesheet_link_tag 'application'
      = javascript_include_tag 'application'
      = csrf_meta_tags
  
    %body
      = yield
  </code></pre>
  
  <p>I then changed the application_controller.rb to</p>
  
  <pre><code>class ApplicationController &lt; ActionController::Base
    layout "application"
    protect_from_forgery
    include SessionsHelper
  end
  </code></pre>
  
  <p>when I run this I get the following error message:
  Missing template layouts/application with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :coffee]}. Searched in: * "/home/coen/Desktop/rails_project/sample_app/app/views" </p>
  
  <p>it seems as if the haml handler not installed.</p>
  
  <p>How can I accomplish this?</p>
