Topic: [Fixtures]

Bang my head against this one.
With rails you can now provide the name of a fixture instead of the id

before;


post_1:
id: 1
user_id: 1

after:

post_1:
user: Jon


But for something like this:

topic_1:
replied_by: Jon
last_post: post_1


it appears to fail. I can't throw the fixture name in?
