python - Django 模板不加载

Question

正在关注 Django 网站的教程，目前在 Pt3( https://docs.djangoproject.com/en/1.11/intro/tutorial03/ )

教程指出:“此代码应创建一个项目符号列表，其中包含教程 2 中的“发生了什么”问题。该链接指向问题的详细信息页面。”添加模板并运行服务器后，我仍然只看到这个 previous page and no updated template，这里有什么问题吗？感谢您的帮助!

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

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

from django.conf.urls import url
from . import views

urlpatterns = [
    #ex: /polls/
    url(r'^$', views.index, name='index'),

    # ex: /polls/5/
    url(r'^(?P<question_id>[0-9]+)/$', views.detail, name='detail'),

    # ex: /polls/5/results/
    url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'),

在 views.py 中删除这个，因为你已经定义了它 2 次。

def index(request):
    return HttpResponse("At Polls Index")
