In theory there's nothing stopping you from turning prefetch_related int on explicit fetch_related: queryset = Foo.objects.filter(Foo.publish_date <= datetime.date.today()) queryset = fetch_related(queryset[:10], Foo.author) # with a future results = await queryset.all() fetch_related(results, Foo.category) # with a result set, returns identity -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
