title: conditions in contain cakephp find
body: <p>is it good or bad practice in CakePHP to have conditions set in the <code>contain</code> of a find query like:</p>
  
  <pre><code>$data = $this-&gt;SomeModel-&gt;find('all', array(
      'contain' =&gt; array(
          'AnotherModel' =&gt; array(
              'conditions' =&gt; array(
                  // some conditions
              )
          )
      )
  ));
  </code></pre>
  
  <p>In which cases will putting conditions inside a contain be useful, and when should I use it or not. Sorry, this is still confusing to me.</p>
  
  <p>Thank you</p>
