尝试单击“新颜色集”按钮时出现此错误：
NoReverseMatch at /colorsets/new/
Reverse for 'user_logout' not found. 'user_logout' is not a valid view function or pattern name.
我已经通过 StackOverflow 和其他网站上的其他地方进行了广泛的查看，但似乎无法找到问题所在。到目前为止，我可以说我的所有代码都是正确的，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'))
"""
from django.conf.urls import url

urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^$',views.index,name='index'),
url(r'^accounts/',include('accounts.urls',namespace='accounts')),
url(r'^colorsets/',include('colorsets.urls',namespace='colorsets')),
]
如果您需要查看其他内容，请告诉我。
new_color问题出在您的命名空间中指定的 url 下的模板中colorsets。你肯定用它作为{% url 'user_logout' %}，而你应该用它像{% url 'accounts:user_logout' %}。只需添加命名空间即可。
