Answer 1

Die folgende Zeile Sie verursacht Probleme

profile.key_expires = (timezone.now() + datetime.timedelta(days=2)), 

Sie setzen key_expires als Tupel statt String. Ändern Sie es in

profile.key_expires = timezone.now() + datetime.timedelta(days=2) 

Entfernen Sie auch das Komma vom Ende der oben genannten Zeile.
