TemplateDoesNotExist位于/​​ home_page.html

Question

运行python manage.py runserver时出现错误“ /home_page.html处的TemplateDoesNotExist”。我的文件夹结构包含在下面的屏幕截图中。运行服务器时如何显示模板？

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',
        ],
    },
},
]


This is the Traceback:

Answer 1

在模板文件夹中，创建一个具有您应用名称的文件夹，并将home_page.html放在其中。

所以结构看起来像这样：

Project_dir
    app_dir
        templates
            app_dir
                home_page.html

Answer 2

您是否尝试过显式设置模板加载器？

'loaders': [
     'django.template.loaders.filesystem.Loader',
     'django.template.loaders.app_directories.Loader'
]

对我有用
