title: CakePHP Routes - Generate appropiate links for /:controller/:id/ with html helper
body: <p>I have this route set up, and manually entering the url works:</p>
  
  <pre><code>Router::connect('/:controller/:id/*',
      array('action' =&gt; 'view'),
      array('pass'=&gt;array('id'), 'id' =&gt; '[0-9]+'));
  </code></pre>
  
  <p>However, with html->link, I can't generate a link without the action.</p>
  
  <pre><code>$this-&gt;Html-&gt;link('linkName', array(
      'controller' =&gt; 'controllerName',
      'action' =&gt; 'view',
      $id, $slug));
  </code></pre>
  
  <p>generates controllerName/view/id</p>
  
  <pre><code>$this-&gt;Html-&gt;link('linkName', array(
      'controller' =&gt; 'controllerName',
      $id, $slug));
  </code></pre>
  
  <p>generates controllerName/index/id</p>
  
  <p>How can I generate the url controller/id with html helper?</p>
  
  <p>Thanks!</p>
