Thanks Donn, for the suggestion, but I'm actually not getting the data via a form, I'm using the ORM in a long-running script.
I've figured out one way to do this: in overriding the save() method, the self instance passed in has the new values; simply use self.id to retrieve the prior version, compared its values with those of the still-unsaved self instance. Seems to work just fine.
