Mám spätnú väzbu:

Zaujímalo by ma, či sa niekto nedávno stretol s podobným problémom alebo či ma môže nasmerovať správnym smerom na jeho vyriešenie. Ďakujeme za radu.

odpovede:

Myslím, že toto je vaša spätne nekompatibilná zmena:

• Make paginator.page_range iterátor

Ak chcete tento problém vyriešiť, vráťte zoznam z items() metóda:

def items(self):
post_queryset = Question.objects.all().order_by("-created")
paginator = Paginator(post_queryset, 12)
return list(paginator.page_range)

Poznámka: Zďaleka nie som odborníkom na Django a rámec Sitemap - mohol by existovať lepší spôsob, ako to vyriešiť. Dúfam, že by to bol aspoň krok správnym smerom.
