I study django with the help of documentation, like I did everything correctly. But when I go to http://127.0.0.1:8000/polls/ gives an error. Previously, there were no such problems. here polls \ urls.py

from django.conf.urls import url from . import views app_name = 'polls' urlpatterns = [ # ex: /polls/ url(r'^$', views.index, name='index'), # ex: /polls/5/ url(r'^(?P<question_id>[0-9]+)/$', views.detail, name = 'detail'), # ex: /polls/5/results/ url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'), # ex: /polls/5/vote/ url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'), ]

polls / views.py

 from django.shortcuts import render, get_object_or_404 from .models import Choice, Question from django.core.urlresolvers import reverse # Create your views here. from django.http import HttpResponse, HttpResponseRedirect from django.template import RequestContext, loader def index(request): latest_question_list = Question.objects.order_by('-pub_date')[:5] template = loader.get_template("polls/index.html") context = {"latest_question_list": latest_question_list} return render(request, 'polls/index.html', context) def detail(request, question_id): question = get_object_or_404(Question, pk=question_id) return render(Request, 'polls/detail.html', {'question': question}) def results(request, question_id): question = get_object_or_404(Question, pk=question_id) return render(Request, 'polls/detail.html', {'question': question}) 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 += 1 selected_choice.save() return HttpResponseRedirect(reverse('polls:results', args= (question.id,)))

mysite \ urls.py

 from django.conf.urls import include, url from django.contrib import admin urlpatterns = [ url(r'^polls/', include('polls.urls')), url(r'^admin/', admin.site.urls), ]
  • Surely the error message will greatly help in its solution. Give also the root urls.py code - Pavel1114
  • @ Pavel1114 added - pythonbek
  • And where is the error message? - Boris Vlasenko

Try this:

 urlpatterns = [ # ex: /polls/5/ url(r'^(?P<question_id>[0-9]+)/$', views.detail, name = 'detail'), # ex: /polls/5/results/ url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'), # ex: /polls/5/vote/ url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'), # ex: /polls/ url(r'^$', views.index, name='index'), ]

    In the urls.py file try to remove this line: app_name = 'polls'
