title: CakePHP won't find new table columns
body: <p>I've recently added a new column to my 'users' table (first_name), however when I use </p>
  
  <pre><code>$this-&gt;User-&gt;find('all')
  </code></pre>
  
  <p>it will not return first_name in the array.</p>
  
  <p>However, if I use</p>
  
  <pre><code>$this-&gt;User-&gt;find('all', array('fields' =&gt; 'first_id'))
  </code></pre>
  
  <p>It returns fine.</p>
  
  <p>I have cleared the cache in tmp/cache/model but the problem still persists</p>
  
  <p>Any ideas why I'm having this problem?</p>
