注销时找不到页面，知道为什么注销不起作用吗？
Page not found when I log out, any idea why the logging out doesn't work?
使用 django 开发社交应用程序并单击注销不再有效，出于某种原因我得到：找不到页面 (404)
找不到与查询匹配的配置文件
请求方式：GET
请求 URL：http://127.0.0.1:8000/logout
提出者：network.views.
使用 project4.urls 中定义的 URLconf，Django 按以下顺序尝试了这些 URL 模式：
行政/
[姓名='all-profiles-view']
[姓名='profile-view']
当前路径，注销，匹配上一个。
还有一种简单的方法可以使用户的名字可以从指向他们的个人资料（ProfileDetailView）的任何页面上点击吗？

看着你的urlpatterns。在 logout.
之前你有 profile-view
path("<slug>", ProfileDetailView.as_view(), name="profile-view")
.
.
.
path("logout", views.logout_view, name="logout")
并且当您的注销 URL 与 slug 匹配并且您的 ProfileDetailView 被调用时，因为您的 ProfileDetailView 在 logout_view 之前被评估。因此，请更改网址的顺序，因为 http://127.0.0.1:8000/ 之后的每个 value 都匹配该模式并将被调用。因此，请重新订购您的 urls.py 并检查。
所以通过查看 urls.py 不会影响将此 ProfileDetailView 放在 urls 的底部。
对于第二部分，点击 username 调用 ProfileDetailView 将您的 html 更改为
<li class="nav-item">
<a class="nav-link" href="{% url 'profile-view' user.username %}"><strong>{{ user.username }}</strong>.
</a>
</li>

看着你的urlpatterns。在 logout.
profile-view
path("<slug>", ProfileDetailView.as_view(), name="profile-view")
.
.
.
path("logout", views.logout_view, name="logout")
并且当您的注销 URL 与 slug 匹配并且您的 ProfileDetailView 被调用时，因为您的 ProfileDetailView 在 logout_view 之前被评估。因此，请更改网址的顺序，因为 http://127.0.0.1:8000/ 之后的每个 value 都匹配该模式并将被调用。因此，请重新订购您的 urls.py 并检查。
所以通过查看 urls.py 不会影响将此 ProfileDetailView 放在 urls 的底部。
对于第二部分，点击 username 调用 ProfileDetailView 将您的 html 更改为
<li class="nav-item">
<a class="nav-link" href="{% url 'profile-view' user.username %}"><strong>{{ user.username }}</strong>.
</a>
</li>
