Thanks, I just bought Rails Recipes and I guess I must've missed that one.
I'll go try it. Thanks!

You probably don't need the complexity of a :through. But you are
definitely looking at a self-referential. Here's the example from Rails
Recipes:
class Person < ActiveRecord::Base
has_and_belongs_to_many :friends,
:class_name => "Person",
:join_table => "friends_people",
:association_foreign_key => "friend_id",
:foreign_key => "person_id"
end
Don't forget to add a friends_people join table to the database. Then you
do controller stuff like: person1.friends << person2
Ignore that (confusing) blog post you were referred to and go buy Rails
Recipes if you need the rest of the details to make this work. Recipe 18
will cut and paste to exactly what you want to do.
Maybe get a new forums too.

Hi there!
I'm working on a little recipe-sharing application, and I want people to
be able to click on a link in a user's profile to add them as "friends". I
imagined it working where once the link was clicked, the user_id of the
friendee and the current_user.id of the friender would be stored in a
database table called friends. I asked about this on a ruby forum, and most
people told me that the best way to do this was using self-referential
has_many :through associations (see:
http://blog.hasmanythrough.com/articles/2006/04/21/self-referential-through).
They also concluded that it was well out of my league, and I guess I agree.
Is there a way to do it my way, without the associations (except for maybe a
simple users has_many friends sort of thing)?
Thanks, and let me know if you need more information!
Dave
