Python 调试=False时出现服务器错误500

我正在尝试使用Django将web应用程序部署到Heroku。我可以在本地运行该应用程序，但当我尝试使用

DEBUG=False

实时加载它时，会出现服务器500错误。如果我将设置更改为

DEBUG=True

，它会工作。我将感谢任何帮助

编辑： 这帮助我获得了错误的电子邮件版本，即缺少“home/css/bootswatch.css”的staticfiles清单条目。。所以现在我担心的是静态文件没有正确配置，但我不知道如何修复它们。我在禁用

collectstatic

的情况下使用它-我必须这样做才能让应用部署。这可能是问题所在吗？我记不起我必须运行的确切命令，但基本上heroku告诉我，在我禁用

collectstatic

之前，它无法部署应用程序。

*新编辑： ，我意识到我必须删除禁用的collectstatic配置变量，然后再次尝试构建。没用。这个错误使我意识到，初学者模板附带的默认静态文件必须位于设置模块内。做了那件事，推了推——还是不起作用。回溯显示我的字体css文件有问题。删除了文件，添加了CDN，然后按下并弹出。现场工程。我希望这对将来的其他人有所帮助

据我所知，当

DEBUG=False

时，唯一的问题是

ALLOWED\u HOSTS

设置。关闭调试后，Django将对照列表检查主机名，如果主机不在允许列表中，则拒绝请求

它通常会得到400分，但如果遇到进一步的问题，则可以得到500分： ，我意识到我必须删除禁用的collectstatic配置变量，然后再次尝试构建。没用。这个错误使我意识到，初学者模板附带的默认静态文件必须位于设置模块内。做了那件事，推了推——还是不起作用。回溯显示我的字体css文件有问题。删除了文件，添加了CDN，然后按下并弹出。现场工程。我希望这对将来的其他人有所帮助
