title: Adding fields dynamically in a nested model form in Rails 3
body: <p>I watched <a href="http://railscasts.com/episodes/73-complex-forms-part-1" rel="noreferrer">http://railscasts.com/episodes/73-complex-forms-part-1</a> and <a href="http://railscasts.com/episodes/74-complex-forms-part-2" rel="noreferrer">http://railscasts.com/episodes/74-complex-forms-part-2</a> but it didn't seem to work for me when trying the code - my assumption is a lot has changed within rails since then. The second issue is I'm using JQuery.</p>
  
  <p>Does anyone know of any tutorials online that might show an easier way to do this? I've already made one nested model form - so its really just the adding/removing fields dynamically part thats killing me.</p>
