Hello, I am terribly sorry to have brought this up here, but I would like to direct some of your attention to the ticket #13184 (http:// code.djangoproject.com/ticket/13184). In a nutshell, you can not raise ValidationError in the to_python method of a custom model field if that field has __metaclass__ = models.SubfieldBase (and, quite frankly, that's something you would like to do, usually), - doing so breaks form validation (the ValidationError is not caught and propagates beyond is_valid method of the form instance).
So that means, that either you have *working* form validation, or you have automatic database-type<->python-type conversion for your custom model fields, not both at the same time. Which is not all that terrible, but the documentation never actually mentions this, which leads me to think, that this is not the way it is supposed to be. Now, to the actual purpose of this message, - I am more than willing to take a stab at this issue, only I am not quite sure how exactly it should be solved. The reply in the tracker mentions three possible ways to fix this: a fix for the documentation, that will possibly mention the fact, that you have to provide custom form logic in order for SubfieldBase to work, two others being the suggestions to alter the existing form logic slightly (I like this idea more, to be honest). It would be really great if someone, who is in in charge (sort of), could provide at least a little insight on the preferred way of solving this, so that it can be fixed before 1.2 release. I would like to mention, that the ticket has a runnable, minimal (- ish) test case attached, that illustrates the problem, in my opinion, quite clearly.
