Hi, I have a design issue and would like to have discuss with whom is interested.
I have 3 tables, A, B, and C, B and C both have a column reference to A. However, B and C is a many to many relation based on the same reference to A. I have created a mapping table D to map B and C. However, in this case, I could not guarantee that any B and C mapping in D would have the same reference to A. I use _before_insert to check and it works but it could not return useful information to the user. It is just skipped the insertion if B and C do not have the same reference to A. I know that I could insert some code in controller or so to warn or return messages to the user. I am just curious if it is possible to accomplish such scenario in model definition. Thanks.
