調試設置為 False 的已部署 django 應用程序上出現 500 錯誤

Question

我知道以前有人問過這個問題，但我已經完成了其他帖子中推薦的所有內容，但我仍然遇到了這個問題。

我添加了必要的允許主機設置 postgres，這樣我就不會在生產白噪聲設置中使用 sqlite 並且我之前運行 heroku 日志時的靜態文件沒有問題 --tail 它顯示變量錯誤，因為我使用的是 sqlite 但是我通過設置 postgres 並運行 migrate 解決了這個問題，所以現在一切看起來都很好，所以我被卡住了

Answer 1

由於您沒有提供有關您的 requirements.txt 和 procfile 的信息，我相信您可以檢查這些文件並仔細檢查您是否寫出了所有必要的信息。

Answer 2

我認為使用數據庫 URI 將是一個更明智的選擇。 在 heroku 上訪問您的應用程序並獲取數據庫 URI。 https://simpleisbetterthancomplex.com/tutorial/2016/08/09/how-to-deploy-django-applications-on-heroku.html
