submitting an empty forms.DateTimeField fails even with models null and blank and required=False for the form field

[Skylar Saveland <skylar.saveland@…>]

If you have a model like:

class Event(models.Model):
    ... 
    end = models.DateTimeField(blank=True, null=True) 
    ...

and a modelform like:

from django import forms from events.models import Event

class EventForm(forms.ModelForm):

    end = forms.DateTimeField(('%m/%d/%Y %H:%M',),

        widget=forms.SplitDateTimeWidget(

            date_format='%m/%d/%Y', time_format='%H:%M',

        ), required=False

    )

    class Meta:

        model = Event

submitting an empty field will cause a validation error.
