Description
Django assumes that all input data in forms can be validated by Form.is_valid() which is not true. Database contraints, e.g. unique, can fail even though they are checked. An application may require communication with other servers while processing data which can lead to errors.
Both Django admin and generic form views should expect that save may fail despite the validation and provide a way to handle those errors easily, e.g. expect ValidationError can be raised by Model.save and ModelForm.save etc.

This would be a fundamental change in the design of Django and should first be discussed on the DevelopersMailingList to find a consensus. Thanks!
