title: Order By on HasMany relationship Laravel 5
body: <p>In my Laravel 5 app, I've got a one-to-many relationship between two models.</p>
  
  <p>My models are: <code>User</code> and <code>Message</code>.</p>
  
  <p>I can access to messages from one user with:</p>
  
  <pre><code>$messages = $user-&gt;messages
  </code></pre>
  
  <p>How can I order these messages by creation date?</p>
  
  <p>Thanks</p>
