我在尝试点击＆＃34;新颜色集＆＃34;时遇到此错误按钮：
NoReverseMatch at /colorsets/new/
Reverse for 'user_logout' not found. 'user_logout' is not a valid view function or pattern name.
我通过StackOverflow和其他网站上的其他地方进行了广泛的搜索，但似乎无法找到问题所在。到目前为止，我可以告诉我所有的代码是正确的，但显然存在问题。

"""colors URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/1.11/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: url(r'^$', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: url(r'^$', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.conf.urls import url, include
2. Add a URL to urlpatterns: url(r'^blog/', include('blog.urls'))

问题出在new_color命名空间中名为colorsets的网址下的模板中。您肯定将其用作{% url 'user_logout' %}，而您应该像{% url 'accounts:user_logout' %}一样使用它。只需添加名称空间。

-在设置文件中，您应该具有这两个代码
LOGIN_REDIRECT_URL = 'home'
LOGOUT_REDIRECT_URL = 'home'
-项目的urls.py文件中必须具有路径（如下所示）
path('users/', include('django.contrib.auth.urls')),
