python之Django 模板不加载

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!

类似问题:Django Template not loading

请您参考如下方法:

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")
