Note that if you set this to point to a :class:`DateTimeField`, only the date
portion of the field will be considered.
This is enforced by model validation but not at the database level.
This is enforced by :meth:`Model.validate_unique()` during model validation
but not at the database level. If any :attr:`~Field.unique_for_date` constraint
involves fields that are not part of a :class:`~django.forms.ModelForm` (for
example, if one of the fields is listed in ``exclude`` or has
:attr:`editable=False<Field.editable>`), :meth:`Model.validate_unique()` will
skip validation for that particular constraint.
