[Django]-Geodjango distance btw points in two models

Time for answer then:

def text1():
for r in Supervision.objects.all():
    try:
        x = Facility.objects.filter(code1=r.code1, code2=r.code2).distance(r.point).order_by('distance')[:1].get()

        r.facilityName = x.facilityName
        r.save()
        print x.primary_name
    except ObjectDoesNotExist:
        print 'Does Not Exist!'
        pass
