Django tutorial : TypeError at /polls/3/vote/ reverse() takes no keyword arguments

Question

I've been working on django project with tutorials and I got this message. When I click radio box to vote, the count in admin goes up but site shows error message instead of loeading templates.It seems like there is something wrong in model.py so I added it.

    selected_choice.save()
    return HttpResponseRedirect(reverse('polls:results', args=(question.id,)))    

def results(reqeust, question_id):
    question = get_object_or_404(Question, pk=question_id)

Answer 1

You are overriding django reverse method with this line of code:

from audioop import reverse

to use django's reverse you should import it:

from django.urls import reverse

also if you still need audioop's reverse you can use synonym with as syntax:

from audioop import reverse as audio_reverse
