I have nodes with a self-referential parent-child one-to-many relation, and a many-to-many relation between nodes and keywords.
I would like to manage orphan keywords. It doesn't work with cascade=delete-orphan which is not adapted to many-to-many relations. I could do it manually, but I can't figure how because nodes can be deleted automatically when deleting a parent node (cascade=delete in parent-child relation). I looked at MapperExtension and SessionExtension without success... Can anybody help me ? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
