Hmm, you shouldn't have any dots in there, and this looks different
that your earlier examples. Perhaps you should check the docs [1].
I should also note that in the example I gave, I did not look at you
models. Now that I have, it seems you are confused more than I
originally thought. You don't need to refer to each model, just
follow the relationship with double underscores. try:
Book.objects.all().select_related().order_by('-book__avg_rating')[0:10]
Actually, as you have `related_name` set (to 'stats'), I believe this
may be what you want:
Book.objects.all().select_related().order_by('-stats__avg_rating')[0:10]
