I have the following model:
from django.contrib.gis.db import models as g
class Neighborhoods(Model):
area = g.PolygonField()
def point(self):
#TODO:something better than this horrible hack of 2 db round trip
return
Neighborhoods.objects.annotate(p=Centroid("area")).get(pk=self.id).p
How do I calculate point() without a 2nd roundtrip to the db?
