I would probably take this approach. One reason is, if something in the order were to fail, but the user registration was successful, it would seem rather inconsiderate to fail the entire thing and make them register again too. > > Which is better? > > As always, it depends on your application. However, I wouldn't think that it makes much sense in most applications to try and wrap the User inside the Order. That would seem to begin a slippery slope towards a whole bunch of "User-oriented" methods in your Order. In some cases it might make sense to do this, but overall this doesn't sound like a good approach. > And what about cases of LOGGING or STATS (rather than USER) that really > aren't an ORDER's concern but may need to be affected as well during the > save() function? > AOP --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "CFCDev" group.
