points_sum = models.PositiveIntegerField(default=0)
class Member(models.Model):
group = DenormalizedForeignKey(
Group, models.CASCADE,
trackers=[
DenormalizedTracker(
# name of field to store denormalized count of active members
"members_count",
# callback to determine whether object should be counted or not
callback=lambda obj: obj.active,
# QuerySet filter to count only suitable objects
query=models.Q(active=True)),
DenormalizedTracker(
# multiple denormalized fields tracked for single foreign key
"points_sum",
