datetime blank=True

[wim@…]

In a model, having a DateTimeField with blank = True, I get an error when leaving the value blank on saving.

My model is, simplified:

class Place(models.Model):
    name = models.CharField(max_length=100)

class Event(models.Model):
    user = models.ForeignKey(User)
    place = models.ForeignKey(Place, blank=True)
    starttime = models.DateTimeField(blank=True)

class EventForm(forms.ModelForm):
    class Meta:
        model = Event
        exclude = ['owner']

def edit_event(request, event_id=False):
    userid = request.session['loggedinas']
    if request.POST:
        event = EventForm(request.POST)
        if event.is_valid():
            cleaned_data = event.cleaned_data
            event = Event( user_id = userid )
            fields = ['name', 'description', 'starttime', 'endtime', 'photo', 'file']
            for fieldname in fields:
                setattr( event, fieldname, cleaned_data[fieldname])
                return HttpResponseRedirect('/success')
     ...

Reformatted description. Please use preview before posting. Also, it would be ever so much more helpful if you'd specify what exact error you get. Why leave us guessing with the vague "an error"?
