Python 模板呈现期间出现Django错误，因为URL标记

错误：

URL.py：

from django.shortcuts import get_object_or_404, render
from .models import College

# Create your views here.
def index(request):
    latest_college_list = College.objects.order_by('college_name')
    context = {'latest_college_list': latest_college_list}
    return render(request, 'app/index.html', context)

def detail(request, college_id):
    college = get_object_or_404(College, pk=college_id)
    return render(request, 'app/detail.html', {'college':college})

有人知道问题是什么吗？

问题是：

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^$', include('app.urls')),
    url(r'^login/$', include('login.urls')),
    url(r'^admin/', admin.site.urls),
]

应该是

url(r'^$', include('app.urls')),

注意，

$

应该被删除，因为它表示正则表达式模式的结束，并且它不会发现包含的url模式

其次，您需要在

include

中明确指定

名称空间。更多关于这方面的信息，请参阅

同样，在
登录/
URL模式匹配后删除
$
 你的错误是什么？另外，您的根url配置是什么样子的？非常感谢！
