        )
    else:
        selected_choice.votes = F("votes") + 1
        selected_choice.save()
        # Always return an HttpResponseRedirect after successfully dealing
        # with POST data. This prevents data from being posted twice if a
        # user hits the Back button.
        return HttpResponseRedirect(reverse("polls:results", args=(question.id,)))

 

polls/urls.py 파일 수정

    path("<int:pk>/results/", views.ResultsView.as_view(), name="results"),
    path("<int:question_id>/vote/", views.vote, name="vote"),
]

 

mysite/settings.py 파일 수정

ALLOWED_HOSTS 다음과 같이 수정

ALLOWED_HOSTS = ['.localhost', '127.0.0.1', '[::1]']

테이블에 row 추가

DBeaver 접속해서 polls_question에 row 추가하기

 

마찬가지로 polls_choice에도 row 추가


결과 확인

서버 실행하고, localhost:8000/pulls에 접속

$ python manage.py runserver
