使用 Digital Ocean Apps 将 Django 上传到生产环境时出现问题，“collectstatic no input”错误

Question

我正在尝试使用 Digital Oceans Apps 将我的 django 应用程序上传到生产服务器。但是我不断收到这个错误，我已经尝试了一切。我看到在下面的日志中，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，现在已经删除了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，但答案涉及使用 Docker，（传入的愚蠢问题）这不会是多余的，因为我正在使用 Digital Ocean 的新 PaaS 服务？非常感谢我如何克服此错误，如果您需要我的更多文档，请告诉我。

Answer 1

如果您的应用没有静态文件，您可以添加以下环境变量：DISABLE_COLLECTSTATIC = 1

Answer 2

您的 DATABASES 设置似乎是为本地开发配置的，即它指向您的 localhost。您需要为您计划在 Digital Ocean 中使用的数据库指定 HOST/PORT/PASSWORD。
