Also, the technique you are using of creating the ModelForm with an instance parameter so as to provide values for fields that are excluded from the form (as described here: http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#using-a-subset-of-fields-on-the-form) is to avoid errors during model save, not form validation. This data is not used during form validation (after all it's for supplying values for the model instance for fields excluded from the form -- so the form knows nothing of these fields and won't attempt to validate them. You seem to be confusing two separate things here -- what's a required field on the form and what's required when saving an instance to the DB. So you have not excluded 'product' from the form, and the form field is required, so when you get a POSTed form that has an empty value for 'product', the form fails to validate. The fix may be as simple as really excluding 'product' from the from, though I'm not sure why you didn't see that 'product' was not actually excluded from the form when looking at it....
