Let's say I have two classes A and B, and I want instances of both classes, to have a list of each other, that is, many-to-many relationship. For a shorthand, "a" means instance of A, and "b" is an instance of B.
For example: "a.bs" is a list, full of instances of class B. Similarly, "b.as" is a list, full of instances of class A. In modelling that relationship I use three tables, one for As, one for Bs, and one for their relationship. If I only append instances of B to some "a.bs", then save all those objects, everything works fine. But if I append instances of A and B, both to "a.bs" and "b.as", then save, I get double rows in the third table. Is there a way around that? P.S. In a very likely case I haven't been completely understood, I'll attach some code to demonstrate my point ;).
