Sorting objects rated using django-secretballot is a little tricky. Simply using order_by causes duplicates. There’s even a warning about it in the Django manual for QuerySet.

I figured out how to rank the objects and avoid duplicates. It’s not that elegant, so if you have a better solution I’d love to hear it.

from django.db.models import Sum

photo_list = Photo.objects.annotate(total_votes=Sum('votes')).order_by('-total_votes')
