Filtering only on Annotations in Django

Question

Taking the example from: http://docs.djangoproject.com/en/dev/topics/db/aggregation/#filter-and-exclude

Publisher.objects.filter(book__rating__gt=3.0).annota         


        

Answer 1

I just facing this kind of problem. And if my interpreation for the problem and expected solution is correct, this is my working solution:
Publisher.objects.annotate(num_books=Count('book')).filter(book__rating__gt=3.0) Just swap filter & annotate position. This is done in Django version 1.9
