Is it possible for EOF to support a reflexive relationship back to the
same Entity with the same relationship property name through a
flattened many-to-many?
Think of a User entity in the case of LinkedIn where users are
"linked" to other users:
User <---->>Connection<<---->User
Connection is the flattened (EOGenericRecord) m:n table with only the
foreign keys as its two primary keys. User.connections simply returns
all the connected users.
I'm imagining that you'd link them up like this:
userA.addObjectToBothSidesOfRelationshipWithKey(userB, "connection");
Any one with experience/gotchas doing this? (No inheritance involved.)
Thanks,
Joe
