Ich kann nicht scheinen, die Korrektur für diesen fortgeschrittenen Fehler in django zu finden. Könnte jemand plz helfen.

Ich habe versucht, es zu lösen, konnte aber nicht, jeder Kommentar soll Link zu einem Kommentar sein.

Dank

Die Fehlerpunkte auf

return redirect('posts:single', pk=post.pk) 

, die den Fehler verursachen können, weil es Ihnen ein username Argument neben der pk passieren erwartet.
