The short answer is: backwards compatibility. Model level validation hasn't always been a thing, with Django initially depending primarily on Form validation. Since it hadn't _always_ been there, it wasn't possible to introduce it, enforce it, and not break most apps out there. There was so much code written that generally assumed it could call `save()` and not have to catch validation errors. For what it's worth, I'm all in favor of making it run on `save()` ... updating the documentation and preparing the community is going to be a mammoth task, however. A safe course through this will take some very careful planning. -- C -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
