mapping

Hi there,

I want to map the following ER schema to rails: I have an entity called "user" which has a self relationship called "has friend", which has an attribute called "status". In code, I would like to run:

User.friends

and it should return me an array of users, containing the users that I'm friend of. It shouldn't matter in which side of the relationship I am (i.e. whether I'm the friender or the friendee). Any thoughts?
