Comment (by Huub Bouma):
I think it's crazy that an order_by changes the amount of records in the
resulting queryset..
Here's a workaround to achieve the sorting without duplicate records in
the queryset:
{{{
from django.db.models import Max
Bar.objects.all().annotate(ordered_fooint=Max('foos__fooint')).order_by('ordered_fooint'))
}}}
