model

Hi there,

I have a model Follow that defines a user_id and a followed_user_id. If you've used Twitter, this should make sense.

I'm trying to make followed_user_id point to a User model, so I can access the user that is being followed through f.followed_user (in the same way that if I have an Entry with belongs_to :user and a user_id column I can use entry.user to get the user.)

How can I do this?

Thanks!
