For some reason I cannot create a record with
{{{
class MyModel(models.Model):
models.DateField(null=True, blank=True)
MyModel(MyDateField='')

It must be either None or a valid date.

Replying to [comment:2 mrts]:
> The problem is that `DateField.to_python()` (or `DateTimeField`) doesn't
treat `''` specially...
Neither does !IntegerField nor !FloatField, eg. It's not clear to me why
Date fields would/should be singled out for special treatment here. Forms
fields consistently handle treating empty strings input as None, but if
you are operating at the model level then you need to use None when you
mean None, not an empty string.
