我想要的是我创建的管理面板，只有在UserLevel模型中权限设置为“admin”的用户才能编辑网站的某些方面。然而，虽然我认为我已经正确编码了所有内容但它无法正常工作。我试图实现这个的方式已经在我的网站的主要内容部分工作。我最好的猜测是，因为我试图在应用程序之间交叉使用某些东西混淆了，尽管这可能是错误的。另外请记住，虽然我确实开始使用干净的代码来模拟来自网站工作部分的代码，但这些代码可能不那么干净，因为我一直在玩它，以至于我只是感到很困惑。所以任何帮助都会非常感激。
要清楚，网站没有错误，这就是我认为代码写得正确的原因。但是，我制作了一个测试小部件，它根本没有显示在主页上（它应该是），也不会显示在我设置的管理面板页面上（它应该显示可能存在的任何小部件），我可以没有添加新窗口小部件的表单显示在管理面板页面上（它给了我一个按钮，转到另一个页面上有表格）。
项目urls.py:
"""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'))
