Python Django页面未找到（404）轮询：详细url问题

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index.html上点击我的问题“What's up”，但这会导致页面未找到错误。代码如下：

py（用于轮询）

当我单击index.html上的链接“What's up？”时，会导致以下错误：

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.

未找到页面（404） 请求方法：获取 请求URL:http://127.0.0.1:8000/polls/%7B%25%20url%20'轮询：详细信息'%20问题。id%20%25 Django使用mysite.URL中定义的URLconf，按以下顺序尝试了这些URL模式： 轮询/[name='index'] 轮询//[name='detail'] 民意测验//results/[name='results'] 投票//vote/[name='vote'] 管理员/ 当前路径polls/{%url'polls:detail'question.id%与这些路径中的任何一个都不匹配。 看到此错误是因为Django设置文件中的DEBUG=True。将其更改为False，Django将显示标准404页面。 我来自一个酒瓶背景，学习Django，发现它组织得很好，除了这个打嗝

我尝试过将question.id改为question.pk。此外，我还尝试过在“polls:detail”周围改引号，但也没有用。

您错过了

{%url%}

标记末尾的

。应该是：

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