title: CakePHP HABTM find ONLY associated model data
body: <p>I have the following relations:</p>
  
  <pre><code>class Platformuser extends AppModel {
   public $hasAndBelongsToMany = array(
      'Service'
   );
  }    
  
  class Service extends AppModel {
   public $hasAndBelongsToMany = array(
      'Platformuser'
   );
  }
  </code></pre>
  
  <p>I am doing a action on the PlatformusersController to get the services associated with this user with the following query:</p>
  
  <pre><code>$this-&gt;Platformuser-&gt;find('all', array(
   'conditions' =&gt; array('Platformuser.id' =&gt; $userId),
  ));
  </code></pre>
  
  <p>It returns everything about Platformuser/Service and I ONLY want the data of the service:</p>
  
  <pre><code>array(
  (int) =&gt; array(
      [Platformuser] =&gt; array(
          [id] =&gt; [1]
          [name] =&gt; [Domingo]
      ),
      [Service] =&gt; array(
          (int) 0 =&gt; array(
                  [id] =&gt; [1]
                  [name] =&gt; [dropbox],
                  [PlatformusersService] =&gt; array(
                     [id] =&gt; [1],
                     [platformuser_id] =&gt; [1],
                     [service_id] =&gt; [1],
                     [modified] =&gt; [2013-10-10 00:00:00],
                     [created] =&gt; [2013-10-10 00:00:00];
              )
          )
      )
  )
  </code></pre>
  
  <p>I want something like:</p>
  
  <pre><code>array(
      [Service] =&gt; array(
          (int) 0 =&gt; array(
                  [id] =&gt; [1]
                  [name] =&gt; [dropbox]
          )
      )
  </code></pre>
  
  <p>Any ideas?.</p>
