title: Pass data to default.ctp (layout file) from random controller in CakePHP
body: <p>I am simply trying to pass data from my controller to my default layout file:</p>
  
  <p>users_controller</p>
  
  <pre><code>$this-&gt;set('fish', 'trout');
  </code></pre>
  
  <p>default.ctp (layout file)</p>
  
  <pre><code>echo "You caught a " . $fish. " from the river.";
  </code></pre>
  
  <p>What I am trying to achieve is: echo $group['Group']['name']; in the default layout file, but the above was my first attempt to understand how the relationship actually works.</p>
  
  <p>Thanks for any advise on this : )</p>
