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.
