Django：TemplateDoesNotExist at /login/（源不存在）

Django：TemplateDoesNotExist at /login/（源不存在）

K s*_*str 4 python authentication django templates

我正在尝试进入 Django，我正在这里和那里学习教程。我正在尝试从官方 Django 教程中向投票应用程序添加登录页面，但即使我按照这个简单的教程进行操作，我还是收到了TemplateDoesNotExist error. 不过，据我所知，Django 正在寻找login.html正确的目录，并给出消息 Source 不存在。

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

Using engine django:

django.template.loaders.filesystem.Loader: /home/kostis/PycharmProjects/secvot/templates/registration/login.html (Source does not exist)

据我所知，Django 尝试加载正确的模板，查看正确的文件夹，但即使模板在那里，也显示错误“源不存在”。

关于我可能做错了什么的任何想法？

'DIRS': [os.path.join(BASE_DIR, 'templates')],

这告诉 Djangotemplates在您的项目目录中查找一个目录（包含manage.py. 的目录。但是您的模板目录在您的内部项目目录中（包含settings.py.

您可以通过执行以下操作之一来修复它：

移动模板目录
更改DIRS设置以指向模板目录的当前位置。
```
'DIRS': [os.path.join(BASE_DIR, 'secvot', 'templates')],
```

添加secvot到您的，INSTALLED_APPS以便app_directories加载程序找到模板目录。如果您这样做，您可以更改DIRS为[]。
