Template loader postmortem
Django tried loading these templates, in this order:

Using engine django:
* django.template.loaders.app_directories.Loader:       
/home/pdlsaroj22/.virtualenvs/venv/lib/python3.5/site-packages/django/contrib/admin/templates/blog/templates/blog/post/list.html(Source does not exist)

                     response = `self.process_exception_by_middleware(e, request)

             raise TemplateDoesNotExist(', '.join(template_name_list), chain=chain)
Exception Type: TemplateDoesNotExist at /
Exception Value: blog/templates/blog/post/list.html, blog/post_list.html

我的 views.py 看起来像这样：

class PostListView(ListView):    
   queryset = Post.published.all()    
   context_object_name = 'posts'    
      paginate_by = 3    
      template_name = 'blog/templates/blog/post/list.html'    

Answer 1

如果您有一个名为 blog 的应用程序（在您的 settings.py 中注册），并且您在 settings.py 的模板目录下将 APP_DIR 设置为 true，那么您的博客应用程序中可能有一个名为 templates 的目录，并且模板中另一个名为 blog 的目录。

如果是这种情况，那么 blog/templates/blog/post/list.html 实际上应该写成：post/list.html，前提是您在博客应用的博客目录中有一个帖子目录。

Answer 2

你必须在settingd.py 所在的位置创建一个名为"templates" 的文件夹，并将你的.html 文件放在这个模板文件夹中。并在以下settings.py 文件中进行更改：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates'), ],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

并且在您的代码中进行如下更改：

class PostListView(ListView):
    queryset = Post.published.all()
    context_object_name = 'posts'
    paginate_by = 3
    template_name = 'list.html'

希望这个答案对你有所帮助。
