python - 没有CSS的Django Admin加载

Question

我创建了一个新的 Django 应用程序，我注意到它的管理页面加载时没有使用 CSS。我根据 this 在 settings.py 中设置了 STATIC_URL 和 STATIC_ROOT解决方案，但它仍然不起作用。

经过一番挖掘，我在管理页面打开 Chrome 开发工具时发现了这个错误

[my_web_page] Refused to apply style from 'http://[my_web_page]/static/admin/css/base.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

[my_web_page] Refused to apply style from 'http://[my_web_page]/static/admin/css/responsive.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

[my_web_page] Refused to apply style from 'http://[my_web_page]/static/admin/css/login.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

[my_web_page] Refused to apply style from 'http://[my_web_page]/static/admin/css/responsive.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

[my_web_page]/:1 Refused to apply style from 'http://[my_web_page]/static/admin/css/login.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

[my_web_page]/:1 Refused to apply style from 'http://[my_web_page]/static/admin/css/base.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. 

我想该应用正在查找我的管理 css，但它拒绝应用该样式。

我尝试添加

import mimetypes

mimetypes.add_type("text/css", ".css", True)

到我的 settings.py，因为我在某处看到了这个解决方案，但无济于事。

感谢您的宝贵时间。

编辑:这是我的 settings.py

编辑 2:我正在使用 pythonanywhere，也许这有什么关系？

Answer 1

如果 Django 管理页面呈现时没有样式，您可能在 settings.py 中设置了 DEBUG=False。

使用DEBUG=False Django 将不再处理静态文件。选中提供文件框。 here

不建议在生产环境中使用 debug=True。

一种处理静态文件的神奇方法是 whitenoise
