I\'m attempting to get over the hurdle of dynamic form fields in Rails -- this appears to be something the framework doesn\'t handle very gracefully. I\'m also using jQuery
I've successfully (and rather painlessly) used https://github.com/nathanvda/cocoon to dynamically generate my forms. Handles associations elegantly and the documentation is very straightforward. You can use it together with simple_form, too, which was particularly useful for me.
