Question

我正在尝试为Heroku构建Django应用，并通过了民意调查教程和Heroku documentation

在使用heroku local或python3 manage.py runserver服务基本的Django-heroku应用程序时，我可以看到一些静态文件已经很好地加载了（特别是/static/lang-logo.png）。但是，当我添加main.css并运行python3 manage.py collectstatic时，css文件将不会显示，并且index.html中的导入也将不会加载。

我已经准备好白噪声最适合在Django应用程序中提供静态文件，因此我正在使用它，并根据对此处类似问题的许多回答设置了settings.py。

Collectstatic似乎正在运行（请参阅下文）。在过去的几天里，我一直在努力解决这个问题，并且在这里经历了数十个相关问题，似乎没有任何事情可以解决。我已经到了互联网的尽头，现在你是我唯一的希望。我的代码在下面，如果我意识到我错过了一些相关的内容，我将更新问题。

将STATIC_URL更改为/static/，出于测试目的，只需设置STATICFILES_DIR = ['hello/static/hello']。白噪声不一定需要排第二。我在最下面运行我的游戏，它与Heroku上的Django多租户应用程序配合使用效果很好。我相信，当您现在推送至Heroku时，您可能不得不再次执行collectstatic。如果第一次创建后它抱怨您的静态文件，请像Heroku所说的here一样将其禁用。

编辑：Heroku不支持SQLite，因此您需要迁移到postgres。这是我做过的事，从未回头。您所要做的就是更改数据库信息和引擎，一切顺利。

当源中有其他静态文件时，为什么不能在django项目中添加静态文件？
