Can a method call inside save() display its return on template?

In my models.py I override the save method like this:

def save(self, *args, **kwargs):

        self.directiondb = get_direction_db(self.nod_id1.id, self.nod_id2.id)

        get_direction_descr(self.nod_id1.id, self.nod_id2.id)

        get_vrd_code(self.nod_id1.id, self.nod_id2.id)

        self.vrd_id = get_vrd_id(self.nod_id1.id, self.nod_id2.id)

        super(Webrequests, self).save(*args, **kwargs)

and it works fine. 

Is it now possible what get_direction_descr() and get_vrd_code() return to be displayed on the template on the fly just after the user selects nod_id1 and nod_id2 from a dropdown list?

Or how I could accomplish sth like this?
