Hi, I need to get a single event at an extension in case of such operation:
obj.colAttr = [x, y, z] right now I will receive: extension.remove(...) for each value currently in colAttr extension.append(...) for x, y and z. what I need is something like: extension.replace(oldvalues, values) with two lists or something like that. Right now my approach (yes, I know this is sick) is: def weComeFrom(): f=inspect.currentframe().f_back.f_back while(inspect.getmodule(f).__name__.startswith('sqlalchemy.')): f=f.f_back return (f.f_lasti, f.f_code) class ImmutableExtension(TefAttributeExtension): active_history = True triggerName = 'immutable' def append(self, state, value, initiator): f = weComeFrom() try: lf = initiator.__tefLastComeFrom except AttributeError: lf = None if len(self._getOldValue(state, initiator)) == 0: initiator.__tefLastComeFrom = f return value elif f == lf: return value else: self.raiseError(state, value, None, initiator) What is the proper way to achieve this? regards, Filip Zyzniewski --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
