Is it possible to examine the session and get a list of all mapped instances that have been changed?
More details: I would like to implement an observer pattern in my application. I would like to let the code make changes to mapped objects as normal, but immediately before (or after) a session flush() I need to notify any interested observers that the state in the mapped objects has changed. I know I could do this by adding my own attribute state tracking to the mapped classes, but I was hoping that since SA is already doing this there may be a way to just make use of SA's change tracking. Has anyone done anything like this? Thanks, Allen --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
