title: How to get parameters from the URL to the model in cakePHP?
body: <p>let's say i have:</p>
  
  <pre><code>http://some-domain/application/controller/action/parameter
  </code></pre>
  
  <p>This is somehow working in cakePHP. Now I want to now what exactly 'parameter' is. But inside the Model. How to get to this information?</p>
  
  <p>I have to say that there is a formular including a 'Next' Button and I want to validate the input inside of the Model in <strong>beforeValidate()</strong>. But I have to know on which page the user was at the time of clicking the submit button. This page is 'parameter'.</p>
