Hi, I'm kind of new at ruby on rails, and I've read many tutorials about this, but I still can't figure out what's wrong.

How could I implement this? I think my solution is very dirty, and I would like to do it better. I think there is an easy way to do this in Ruby, but I can't remember.

Anyway, I want a user to be able to "favorite" items on the site when they click "favorite" off of an "item" I'm assuming I need to use cookies for this but I don't really know the next step. Could anyone point me in the right direction? Thanks! ...
