how do I model self-referential entities?
Hi all -
I am having some trouble figuring out how to model self-referential
entities in Rails.
I have a "group" model, which can have 0 or more "group" objects or 0 or
more "user" objects.
I tried creating a subgroup table that has a parent_group_id and a
child_group_id as foreign keys but can''t figure out how to create the
mapping in my ruby model classes. I can''t come up with the correct
parameters for habtm or has_many :through.
Any help would be appreciated.
Ken
