为什么我在添加到urls.py后收到NameError：Not Defined？

Question

我收到此错误：

NameError at /storefront/
name 'storefront' is not defined

My Urls.Py看起来像这样：

from django.conf import settings
from django.conf.urls import patterns, include, url
from django.conf.urls.static import static
from django.views.generic import TemplateView
from accounts.views import home
from django.contrib import admin   

urlpatterns = patterns('',
url(r"^$", home),
url(r"^storefront/", storefront, name="storefront")

My Views.Py看起来像这样：

def storefront(request):
    latest_entries = Entry.objects.filter()
    context = {'latest_entries': latest_entries}
    return render(request, 'storefront.html', context)

网址或视图中的错误是什么？
