刘老师，我按照您的方法设置了polls/view.py和polls/urls.py但是访问不了polls/34/是为什么呀 from django.urls import path from . import views urlpatterns = [ # ex: /polls/ path('', views.index, name='index'), # ex: /polls/5/ path('<int:question_id>/', views.detail, name='detail'), # 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'), ] from django.shortcuts import render from django.http import HttpResponse # Create your views here. def index(request): return HttpResponse("Hello, world. You're at the polls index.") def detail(request, question_id): return HttpResponse("You're looking at question %s." % question_id) def results(request, question_id): response = "You're looking at the results of question %s." return HttpResponse(response % question_id) def vote(request, question_id): return HttpResponse("You're voting on question %s." % question_id)
