I popped in 0.8b2 and tried something like this: class SubBase(object): ... def MyLoadHandler(instance, context): print "hit the load handler" MyBase = declarative_base(cls=SubBase) event.listen(MyBase, "load", MyLoadHandler) ... class MyDataClass(MyBase): ... do all the declarative stuff ... anInstance=session.query(MyDataClass).first() It doesn't complain about a non-existent event when I install the handler, but the event handler doesn't seem to get called when the instance gets loaded with the query. I'll try and do a minimal little standalone test to make sure it isn't something in my system messing things up, but in theory this should work? -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
