Tags

I created two models, topics and tags, and wrote tests for each model. I associated these models with story and then added a 'tags' field to the story representer. I'm not sure about the tags method on story -- for representer purposes, it seems like we're only interested in the names, but should the method return the whole object?
I am probably missing something but this line confuses me.
Are you are stubbing `story.tags` with `story.tags`?
