Does this make sense? if get_context_hash returns a dict, thats specifically what would *not* work since its not hashable. The scopefunc's return value is placed in a dict keyed against the appropriate Session, so its anything that is actually hashable. Any kind of hashable token that identifies the scope you want (in this case a frame) will do. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
