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
