Django: Why Does the Vote View Return a URL String Instead of Redirecting?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm following the Django tutorial and encountered an issue with the voting process. At first glance, everything appears to work fine until I vote. Instead of redirecting to http://localhost:8000/polls/1/results/, the page remains at http://localhost:8000/polls/1/vote/ and only displays "/polls/1/results/" in the browser. I've reviewed my views and URL configuration below and would appreciate any insights into what might be causing this behavior.

Here are my views:

PYTHON
# question id of results
def results(request, question_id):
   question = get_object_or_404(Question, pk=question_id)
   return render(request, "polls/results.html", {"question": question})

# what question are you voting on?
def vote(request, question_id):
    question = get_object_or_404(Question, pk=question_id)
    try:
        selected_choice = question.choice_set.get(pk=request.POST["choice"])
    except (KeyError, Choice.DoesNotExist):
        # Redisplay the question voting form
        return render(
            request,
            "polls/detail.html",
            {
                "question": question,
                "error_message": "You didn't select a choice.",
            },
        )
    else:
        selected_choice.votes = F("votes") + 1
        selected_choice.save()
    return HttpResponse(reverse("polls:results", args=(question.id,)))

And here is my URL configuration:

PYTHON
# ex: /polls/5/results/
path("<int:question_id>/results/", views.results, name="results"),
# ex: /polls/5/vote/
path("<int:question_id>/vote/", views.vote, name="vote"),

Any help or insights would be greatly appreciated.

Django Redirect Issue in Voting Process

I've identified the issue in your code. The problem is in your vote function where you're using HttpResponse incorrectly for redirection.

The Problem

In your vote function, you're returning:

PYTHON
return HttpResponse(reverse("polls:results", args=(question.id,)))

This doesn't redirect to the results page - it simply returns the URL path as text content to the browser. That's why you're seeing "/polls/1/results/" displayed in the browser while staying on the vote page.

The Solution

You should use HttpResponseRedirect instead of HttpResponse to perform a proper redirect:

PYTHON
from django.http import HttpResponseRedirect
# ...

def vote(request, question_id):
    # ... existing code ...
    else:
        selected_choice.votes = F("votes") + 1
        selected_choice.save()
    return HttpResponseRedirect(reverse("polls:results", args=(question.id,)))

Make sure you've imported HttpResponseRedirect at the top of your file:

PYTHON
from django.http import HttpResponseRedirect
from django.urls import reverse

This change will properly redirect the user to the results page after voting, instead of just displaying the URL as text.
