ModelForm save() behavior contradicts with Model object validation documentation.

[vinod@…]

The documentation at ​http://docs.djangoproject.com/en/dev/ref/models/instances/#validating-objectsstates that:
"Note that full_clean() will not be called automatically when you call your model’s save() method, nor as a result of ModelForm validation."

However, this is contradicted by the documentation at ​http://docs.djangoproject.com/en/dev/topics/forms/modelforms/ that states that:
"Note that save() will raise a ValueError if the data in the form doesn't validate -- i.e., if form.errors evaluates to True."

It appears that save() shouldn't check validation. That's what is_valid() does, throwing a ValidationError if necessary.

Change UI/UX from NULL to False.

Actually the docs are correct, but I'll add some clarifying text.
