# I need the best idiomatic way of getting a map of users and their points. 
# The values/annotation combo *almost* gives me what I want, but doesn't return
# full user objects, only their ids.

>>> Points.objects.values('user').annotate(total_points=Sum('amount'))
[{'total_points': 40, 'user': 1}, {'total_points': 30, 'user': 2}]

# I've opted for something like this, instead:

Points.objects.users().annotate(total_points=Sum('points__amount'))

# and the method, on the QuerySet/Manager:
     def users(self):
        user_ids = self.values_list('user', flat=True)
        return User.objects.filter(id__in=user_ids)
