我正在使用amazon ec2和bitnami-djangostack ami部署我的django項目。將項目部署到bitnami後，django postgresql數據庫中的Relational DatabaseError
當我在本地開發應用程序時，我使用了mysql。但是在部署項目之後，我使用了默認的bitnami postgresql。
現在，我收到以下錯誤：
django.db.utils.DatabaseError: relation "appName_appName" does not exist
LINE 1: SELECT (1) AS "a" FROM "appName_appName" WHERE "appName_a...
^
我不知道爲什麼數據庫命名數據庫兩次（appName_appName）。
這裏是全終端：

「數據庫命名數據庫兩次」 - >「django重複表名兩次」？另外，Django版本？ –
代碼中的函數create_cookbook_for_user有什麼作用？它看起來像是一個信號，這就是失敗發生的地方。 –
當您加入該網站時，您（用戶）會獲得一本食譜。以便該函數創建與該用戶相關的cookbook實例 –
