title: routes in rails - removing actions when setting up a resource
body: <p>I've setup a simple app and added a scaffold to do some of the work for me (I'm a noob).</p>
  
  <pre><code>  resources :cars
  </code></pre>
  
  <p>How do I remove certain actions from the routes? And remove the corresponding urls?</p>
  
  <p>For example I want to keep the 'show' and 'edit' actions &amp; urls. </p>
  
  <p>But I don't want there to be a 'new' 'index' or 'delete'</p>
  
  <p>I understand this is probably a really simple question, but I've not been able to find an answer. </p>
