25777	Django admin/views don't expect forms to fail after validation	Vlastimil Zíma	nobody	"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."	New feature	closed	Forms	1.8	Normal	wontfix			Unreviewed	0	0	0	0	0	0
