This may be more of a Python question, because it is not specifically related to data persistence. Mapper Extensions: http://www.sqlalchemy.org/docs/adv_datamapping.html#advdatamapping_extending can help if you want to catch a hook before a class instance is updated in the database. But if you want to catch the moment when the attribute is changed in memory, consider the possibility that this is not in sqlalchemy's scope. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
