django heroku中的静态文件问题

Problem with static files in django heroku

我对 django 中的这个静态文件有 sam 问题。我成功地将 django 应用程序部署到 heroku,并且该站点在 https://timon-webchat.herokuapp.com/ 中正常工作,但是您如何在没有任何样式或图像的情况下看到它。但是如果在本地运行 python manage.py runserver 一切正常,我可以看到样式、js 代码和图像 请告诉我这里有什么问题是我的 setings.py 文件:

在目录 statifiles 中,我有目录:css、js、admin、app_chat 在thare我有我的样式js代码和图像。那我做错了什么?

为了让 Django 处理您的静态文件,您应该 运行 python manage.py collectstatic。不过,Heroku 应该已经为你做了这件事。 Heroku 不会自动提供您的静态文件,这就是为什么我建议您使用 whitenoise 包。它允许您的 Django 应用程序无需额外配置即可自动提供静态文件。

在此处查看 Django 文档:http://whitenoise.evans.io/en/stable/django.html

同时将 whitenoise 添加到您的 requirements.txt
