bulk insert does not invoke pre_save or save() methods of the Document

[dmitry-saritasa]

Unconfirmed.objects.insert([Unconfirmed(shift=s) for s in nlu.items()])

and inside Unconfirmed class I have a save method that is never called during operation above. But if I do

[Unconfirmed(shift=s).save() for s in nlu.items()]

then everything works as expected. Do I miss something?

def save(self, *args, **kwargs):
        """
        save handler
        """
        if self.school:
            if not self.department:
                self.department = self.school.department
            if not self.district:
                self.district = self.school.district

        # speed-up fields
        self.supervisor = self.department.supervisor
        self.supervisor_name = self.supervisor.fullname
        self.supervisor_phone = self.supervisor.phone_cell or self.supervisor.phone_home
