Alternatively, you could set expire_on_commit=False on your sessionmaker() so that the commit() operation leaves the current in-memory state in place. The latter option would be why your test program works in 0.4, there wasnt any expire_on_commit behavior. . --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
