TemplateDoesNotExist在/

HeJ小鼠！这里的许多线程都有相同的标题，但没有一个解决了我的问题。我有一个Django网站可以访问/管理员（但它看起来很难看）。但在/上会出现以下错误页面（DEBUG = True中的settings.py）：

Template-loader postmortem

Django tried loading these templates, in this order:

    Using loader django.template.loaders.filesystem.Loader:  
        /home/django/django/templates/iecl_dev/index.html (File does not exist)  
    Using loader django.template.loaders.app_directories.Loader:  
        /usr/lib/python2.7/dist-packages/django/contrib/auth/templates/index.html (File does not exist)  
        /usr/lib/python2.7/dist-packages/django/contrib/admin/templates/index.html (File does not exist)

事实上，文件/home/django/django/templates/iecl_dev/index.html确实存在，我也尝试chmod o+r index.html但没有成功。

python iecl_dev/manage.py runserver 0.0.0.0:0的输出是

Validating models...

0 errors found  
Django version 1.4.5, using settings 'iecl_dev.settings'  
Development server is running at http://0.0.0.0:0/  
Quit the server with CONTROL-C.

所以这里的一切似乎都很好。

令我困惑的是：运行* .py文件时会自动创建* .pyc文件，对吧？在python iecl_dev/manage.py runserver 0.0.0.0:0之后创建了一个文件/home/django/django/iecl_dev/settings.pyc。但是当我在Web浏览器中加载页面时，它不会被创建。这是否意味着，settings.py永远不会被加载？ Django怎么说，存在的文件不存在？

Edit¹：
我的settings.py看起来如下：

Edit³：
好。这个问题现在已经解决了。解决方案是不同事物的集合体。其中一个问题是缺少权利。执行Django的用户无法列出templates /目录的内容。 chmod o+x templates/完成了这项工作。然后在settings.py中有一些设置，它们改变了从templates / iecl_dev /到iecl_dev / templates /寻找模板的位置。我在Web浏览器的错误消息中看到了这个错误的路径。但仅仅将settings.py恢复为旧版本是不够的。某些服务需要重新启动。我只是重新启动机器，一切都很好。奇迹般地，/ admin /页面现在看起来也不错。

非常感谢您的所有提示。

根据您的展示，我认为您的项目布局可能存在问题。

通常，设置如下：

├── manage.py
├── yourproject
│   ├── __init__.py
│   ├── settings.py
│   ├── templates
│   ├── urls.py
│   ├── wsgi.py
│   └── wsgi.pyc
├── yourfirstapp
│   ├── __init__.py
│   ├── admin.py
│   ├── models.py
│   ├── templates
│   ├── tests.py
│   ├── urls.py
│   └── views.py
├── yoursecondapp
    ├── __init__.py
    ├── admin.py
    ├── models.py
    ├── templates
    ├── tests.py
    ├── urls.py
    └── views.py

正如您所看到的，项目中的每个应用都可以拥有自己的templates目录。yourproject有点特别，因为它还存储了唯一的文件，例如settings.py和{ {1}}。但是，您可以考虑将其用作应用程序。

现在，如果您想使用wsgi.py中存储的模板，则必须在yourproject/templates设置中添加yourproject。

有帮助吗？如果没有，您可以使用项目布局编辑原始帖子吗？

答案 1 :(得分：5)

原因可能是django正在尝试使用您的setting.py文件在目录中查找您的模板目录 实际上，templates目录位于父目录中。 尝试在settings.py中执行类似的操作

SETTINGS_PATH = os.path.dirname(__file__)
PROJECT PATH = os.path.join(SETTINGS_PATH, os.pardir)
PROJECT_PATH = os.path.abspath(PROJECT_PATH)
TEMPLATES_PATH = os.path.join(PROJECT_PATH, "templates")

TEMPLATE_DIRS = (
    TEMPLATES_PATH,
)

错误通常是由于模板目录

配置错误造成的

答案 2 :(得分：2)

我浪费了很多时间试图弄清楚我的'templates'目录出了什么问题，然后弄清楚了：

您可能已经忘记在TEMPLATE_DIR的以下段中添加settings.py了：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        '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',
            ],
        },
    },
]

因此它应该有'DIRS': [TEMPLATE_DIR,],而不是'DIRS': [],

答案 3 :(得分：0)

我知道这已经晚了，但是这里提到的解决方案对我不起作用。所以这里是有效的：

  1. 在 settings.py 文件中，将您的 appConfig 添加到已安装的应用中。
INSTALLED_APPS = [ '...', 'AppName.apps.AppNameConfig', ]

  1. 创建模板目录 appName/templates/appName。 （其中 appName 是您应用的名称）。

  2. 当你调用你的渲染函数时，你可以传递它templates.name.html。像这样：

return render(request, 'templates/blog.html')
