Question

我知道这已经被问过了，但是我已经完成了其他帖子中建议的所有操作，但是我仍然遇到问题。

我添加了必要的允许主机设置postgres，这样我就不会在生产中使用sqlite 白噪声设置而且以前我运行heroku日志时我的静态文件没有问题-因为我使用的是sqlite，所以它显示了可变错误，但是我通过设置postgres并运行migration解决了这一问题，因此现在一切似乎都很好，所以我被卡住了

Answer 1

由于您没有提供有关requirements.txt和procfile的信息，所以我确定您可以检查这些文件，并再次检查是否已写出所有必要信息。

Answer 2

我认为使用数据库URI将是一个更明智的选择。在heroku上获取您的应用程序并获取数据库URI。 https://simpleisbetterthancomplex.com/tutorial/2016/08/09/how-to-deploy-django-applications-on-heroku.html

在已部署的django应用程序上将500错误设置为False
