我的django应用程序存在一个大问题：在我停止处理我的应用程序一个月后，我得到了错误＆＃34;在reverse（）的/ argument处的TypeError必须是一个序列＆＃34; 当我加载页面。
完全错误：

The `urlpatterns` list routes URLs to views. For more information please see:

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'))
