TemplateDoesNotExist at /
提问by user3506025
Hej! Many threads here had the same caption, but none of them solved my problem. I have a Django site an can access /admin (but it looks ugly). But on / there appears the following error page (DEBUG = Truein settings.py):
嘿！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。我有一个可以访问 /admin 的 Django 站点（但它看起来很难看）。但是在 / 出现以下错误页面（DEBUG = Truein 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)
In fact, the file /home/django/django/templates/iecl_dev/index.html does exist and I also tried chmod o+r index.htmlwithout success.
事实上，文件/home/django/django/templates/iecl_dev/index.html 确实存在，我也尝试过chmod o+r index.html没有成功。
The output of python iecl_dev/manage.py runserver 0.0.0.0:0is
的输出python iecl_dev/manage.py runserver 0.0.0.0:0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.
so everything seems fine here.
所以这里一切都很好。
What perplexes me: The *.pyc files are created automatically when *.py files are run, right? After python iecl_dev/manage.py runserver 0.0.0.0:0there is a file /home/django/django/iecl_dev/settings.pyccreated. But it is not created, when I load the page in my web browser. Does that mean, the settings.py is never loaded? And how can Django say, a file, which exists, would not exist?
令我困惑的是：*.pyc 文件是在运行 *.py 文件时自动创建的，对吗？之后python iecl_dev/manage.py runserver 0.0.0.0:0有一个文件/home/django/django/iecl_dev/settings.pyc创建。但是当我在我的网络浏览器中加载页面时，它没有被创建。这是否意味着 settings.py 永远不会加载？Django 怎么能说一个存在的文件就不存在呢？

Edit3:
Ok. This is solved for me now. The solution was a conglomerate of different things. One of the problems was the missing rights. The user that executes Django, could not list the contents of the templates/ directory. chmod o+x templates/did the job. Then there were some settings in the settings.py, that changed the place to look for the templates from templates/iecl_dev/ to iecl_dev/templates/. I saw this wrong path in the error message in my web browser. But simply reverting the settings.py to the old version, was not enough. Some service(s) needed to be restarted. I simply rebooted the machine and everything was fine. Miraculously, the /admin/ page now looks nice as well.
编辑3：
好的。这已经为我解决了。解决方案是将不同事物组合在一起。问题之一是缺少权利。执行 Django 的用户无法列出模板/目录的内容。chmod o+x templates/完成了工作。然后在settings.py中有一些设置，将查找模板的位置从templates/iecl_dev/改为iecl_dev/templates/。我在 Web 浏览器的错误消息中看到了这个错误的路径。但是仅仅将 settings.py 恢复到旧版本是不够的。某些服务需要重新启动。我只是重新启动了机器，一切都很好。奇迹般地，/admin/ 页面现在看起来也不错。
Many thanks for all your tips.
非常感谢您提供的所有提示。

From what you've shown, I think you may have a problem with your project layout.
从您所展示的情况来看，我认为您的项目布局可能有问题。
Usually, it is set as follows :
通常，它设置如下：
├── 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
As you can see, each app inside your project can have it's own templatesdirectory.yourprojectis a bit particuliar, because it also stores unique files, such as settings.pyand wsgi.py. However, you can consider and use it as an app.
如您所见，项目中的每个应用程序都可以拥有自己的templates目录。yourproject有点特殊，因为它还存储了独特的文件，例如settings.py和wsgi.py。但是，您可以考虑将其用作应用程序。
Now, if you want to use a template stored in yourproject/templates, you'll have to add yourprojectto your INSTALLED_APPS?settings.
现在，如果您想使用存储在 中的模板yourproject/templates，您必须添加yourproject到您的INSTALLED_APPS?settings 中。
Does it helps ? If not, can you edit your original post with your project layout ?
它有帮助吗？如果没有，你能用你的项目布局编辑你的原始帖子吗？

The reason might be that django is trying to look for your templates directory in the directory with your setting.py file Whereas actually the templates directory is in the parent directory. Try doing something like this in your settings.py
原因可能是 django 试图在包含 setting.py 文件的目录中查找模板目录，而实际上模板目录位于父目录中。尝试在你的 settings.py 中做这样的事情
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,
)
The error usually is due to incorrectly configured templates directory
错误通常是由于模板目录配置不正确

I wasted a lot of time trying to figure out what was wrong with my 'templates'directory and figured out :
我浪费了很多时间试图找出我的'templates'目录出了什么问题并想出了：
You may have forgotten to add TEMPLATE_DIRin the following segment of settings.py:
您可能忘记添加TEMPLATE_DIR以下部分settings.py：
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',
],
},
},
]
So it should have 'DIRS': [TEMPLATE_DIR,],instead of 'DIRS': [],
所以它应该有'DIRS': [TEMPLATE_DIR,],而不是'DIRS': [],
