如何解决无法将Django上传到带有Digital Ocean Apps的生产环境，“收集静态无输入”错误
我正在尝试使用Digital Oceans Apps将django应用程序上传到生产服务器。但是，我一直收到此错误，并且我已经尝试了一切。我在下面的日志中看到有一个$ heroku config:set DISABLE_COLLECTSTATIC=1，我之前将此应用程序注册为heroku git，但从未将其投入生产，而现在已删除了Heroku的所有痕迹。我对为什么会收到此错误感到困惑。
下面是settings.py和我的数字海洋日志

我看到其他人提到了确切的问题here，但是答案涉及到使用Docker（愚蠢的问题），这不是多余的，因为我正在使用Digital Ocean的新PaaS服务吗？非常感谢您如何克服此错误，如果您需要我的更多文档，请告诉我。
解决方法
您的DATABASES设置似乎已配置用于本地开发，即指向您的localhost。您需要为计划在Digital Ocean中使用的数据库指定HOST / PORT / PASSWORD。
