找不到 Django 页面 (404) 民意调查:详细信息 URL 问题

Question

在 Django 教程中，它要求我们将视图调整为通用视图。发布后，我可以在索引处单击我的问题"怎么了".html但它会导致页面未找到错误。下面是代码：

urls.py(用于投票(

from django.urls import path
from . import views
app_name='polls'
urlpatterns= [ 
    #ex: /polls/
    path('',views.IndexView.as_view(),name='index'),
    #ex: /polls/5/
    path('<int:pk>/',views.DetailView.as_view(),name='detail'),
    #ex: /polls/5/results/
    path('<int:pk>/results/',views.ResultsView.as_view(),name='results'),
    #ex: /polls/5/vote/
    path('<int:question_id>/vote/',views.vote,name='vote'),
]

索引.html

{% load static %}
<link rel="stylesheet" type="text/css" href="{% static 'polls/style.css' %}">
{% if latest_question_list %}
    <ul>
    {% for question in latest_question_list %}
        <li><a href="{% url 'polls:detail' question.id %">{{ question.question_text }}</a></li>
    {% endfor %}
    </ul>
{% else %}
    <p>No polls are available.</p>
{% endif %}

views.py

from django.shortcuts import render,get_object_or_404
from django.http import Http404,HttpResponseRedirect
from django.urls import reverse
from django.views import generic

# Create your views here.
#from django.http import HttpResponse
from django.template import loader
from .models import Question, Choice
class IndexView(generic.ListView):
    template_name = 'polls/index.html'
    context_object_name = 'latest_question_list'
    def get_queryset(self):
        """Return the last five published questions."""
        return Question.objects.order_by('-pub_date')[:5]
class DetailView(generic.DetailView):
    model = Question
    template_name = 'polls/detail.html'
class ResultsView(generic.DetailView):
    model = Question
    template_name = 'polls/results.html'

当我在index.html单击链接"怎么了？"时，它会导致我出现以下错误：

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/polls/%7B%25%20url%20'polls:detail'%20question.id%20%25
Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
polls/ [name='index']
polls/ <int:pk>/ [name='detail']
polls/ <int:pk>/results/ [name='results']
polls/ <int:question_id>/vote/ [name='vote']
admin/
The current path, polls/{% url 'polls:detail' question.id %, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

我来自瓶子背景并学习 Django，发现它组织得很好，除了这个打嗝。

我尝试将 question.id 更改为 question.pk。另外，我尝试更改"polls：detail"周围的引号，但也没有帮助。

您错过了 index.html 中 {% url %} 标记末尾的尾随}。它应该是：

 <li><a href="{% url 'polls:detail' question.id %}">{{ question.question_text }}</a></li>
