Model + Form validations

Some of Django's choices on how to handle data integrity are wrong, or at the very least, unexpected to the uninitiated developers. I'm not here to pass judgement; like many people, I'd just like to get back to doing real work. Some notes on how to stay safe in Django:

What should I know?

• Django now has both Form validations and Model validations
• Django used to only have Form validations
• Form’s is_valid() performs model validation automatically
• full_clean() is never actually called by Django (see ticket #13100)
