我正在尝试使用django 1.9和python 3.5在虚拟环境中创建我的域中的博客。所以在pythonanywhere上部署时。我能够渲染html。这是追溯。

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

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

                     response = `self.process_exception_by_middleware(e, request)
File "/home/pdlsaroj22/.virtualenvs/venv/lib/python3.5/site-packages/django/core/handlers/base.py" in get_response
                     response = response.render()
File "/home/pdlsaroj22/.virtualenvs/venv/lib/python3.5/site-packages/django/template/response.py" in render
             self.content = self.rendered_content
File "/home/pdlsaroj22/.virtualenvs/venv/lib/python3.5/site-packages/django/template/response.py" in rendered_content
             template = self._resolve_template(self.template_name)
File "/home/pdlsaroj22/.virtualenvs/venv/lib/python3.5/site-packages/django/template/response.py" in _resolve_template
             new_template = self.resolve_template(template)
File "/home/pdlsaroj22/.virtualenvs/venv/lib/python3.5/site-packages/django/template/response.py" in resolve_template
             return select_template(template, using=self.using)
File "/home/pdlsaroj22/.virtualenvs/venv/lib/python3.5/site-packages/django/template/loader.py" in select_template
             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settings.py中已注册），并且您在settings.py中的模板目录下将APP_DIR设置为true，则很可能您的博客应用中有一个名为templates的目录，另一个名为blog的模板目录。

如果是这种情况，那么blog/templates/blog/post/list.html实际上应该写为：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

您必须将名为"templates"的文件夹放在settingd.py中，并将.html文件放在此模板文件夹中。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',
            ],
        },
    },
]

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'

希望这个答案可以帮到你。
