could some one point me to the right direction:
I try to build a model for rails that build up the following:
ClassA -id
ClassA has a relation to many "ClassA" (so it is a reference to itself)
I am searching for the migration and the model.
I a not sure what the correct join table is (I think its a simple 2 columns table ClassA_id, ClassARel_ID -> both point to ClassA) and how to build the model
Thanks!
