You probably want the answer to belong_to both the user and the quiz.

"resource" is probably something you copied from an example (or the docs). You're supposed to put the actual object there, like @answer (assuming you have created the @answer object as an instance variable in your controller)

the url: is going to be a path correlated to the answer routes, which you will define in your routes file. You can use rake routes to figure out what the named routes are.
