title: New to Rails: How to Add New Functions to a Controller that Already Exists?
body: <p>One uses</p>
  
  <pre><code>rails generate controller ControllName function1 function2 etc
  </code></pre>
  
  <p>to generator a controller and functions with views for each function. Once the controller already exists, though, how would I use a similar command to add more functions and views automatically to the controller?</p>
  
  <p>If I try the same generate code (with different method names) again, it wants to override the existing controller.</p>
