当DEBUG=False时出现服务器错误500

pythondjangoherokudeployment
5
我正在尝试使用Django将Web应用程序部署到Heroku。我可以在本地正常运行该应用，但是当我尝试使用DEBUG = False将其实时加载时，会出现服务器500错误。如果我将设置更改为DEBUG = True，它可以正常工作。我会感激任何帮助。
编辑：我找到了一个帖子，帮助我获得了错误的电子邮件版本，即Missing staticfiles manifest entry for 'home/css/bootswatch.css'。所以现在我的担心是静态文件未正确配置，但我不知道如何修复它们。我正在使用此默认django/heroku模板，并禁用了collectstatic - 我必须这样做才能使应用程序部署。这可能是问题吗？我记不清我必须运行的确切命令，但基本上heroku告诉我在禁用collectstatic之前无法部署该应用程序。
*新编辑： 由于这个帖子，我意识到我需要移除已禁用的collectstatic配置变量，然后尝试重新构建。但是没有成功。错误提示让我意识到，在起始模板中附带的默认静态文件必须在设置模块内部。于是我做了这件事，推送了代码-仍然不行。Traceback向我展示我的font-awesome css文件出了问题。我删除了这个文件，添加了CDN，再次推送，终于成功了。希望这对将来的某些人有所帮助。

当DEBUG = False时，我知道的唯一问题是ALLOWED_HOSTS设置。当Django关闭调试模式时，它将检查您的主机名是否在允许列表中，并且如果主机不在允许列表中，则会拒绝请求。这通常会导致400错误，但如果遇到其他问题，则可能会出现500错误：Django allowed hosts with port number

通过这个帖子，我意识到我需要移除我的禁用collectstatic配置变量，然后再尝试构建。但是没有成功。错误提示让我意识到，起始模板附带的默认静态文件必须在设置模块内部。我做了这个更改，推送了代码 - 仍然不行。回溯显示我的font-awesome css文件有问题。删除该文件，添加CDN，推送代码，然后一切正常运行。我希望这对未来的某个人有所帮助。
