Hi List, I have this simple model (in declarative style):
class Item( Base ): __tablename__ = 'items' desc = Column( 'desc', UnicodeText(), nullable=False ) email = Column( 'email', UnicodeText(), nullable=False ) How can I trigger an event when the value of 'desc' has changed and the instance is persisted (e.g. via 'session.save(item)')? I would like to send out an e-mail notification when the description of an item changes. But how do I hook it in? regards, -jj --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
