title: Flash messages in Phoenix show module not found
body: <p>I'm attempting to recreate the Flash Messages guide in <a href="http://www.phoenixframework.org/v0.7.2/docs/controllers" rel="nofollow noreferrer">Phoenix</a> however I'm getting a error that states <code>undefined function: Phoenix.Controller.Flash.put/3 (module Phoenix.Controller.Flash is not available)</code></p>
  
  <p><a href="https://i.stack.imgur.com/RR1Ut.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RR1Ut.png" alt="Phoenix module Flash is not available"></a></p>
  
  <p>However:
  I have the <code>plug :fetch_flash</code> in my router.ex browser pipeline.
  I have included the:</p>
  
  <pre><code>use Phoenix.Controller
  alias Phoenix.Controller.Flash
  </code></pre>
  
  <p>at the top of the module definition.
  I'm also attempting to adapt the syntax to my code (where I receive a parameter in the render).</p>
