There has to be a better way, but I can't figure it out and this isn't
very important to my problem. The problem seems to be that the django
form won't actually set a dbmodel DateProperty to None. There does
not appear to be an issue with the StringProperty.
entity = data.save(commit=False)
for property in dbmodel.properties():
if self.request.POST[property]=="":
setattr(dbmodel, property, None)
entity.put()
