將項目部署到bitnami后，django postgresql數據庫中的Relational DatabaseError

Question

我正在使用amazon ec2和bitnami-djangostack ami部署我的django項目。

當我在本地開發應用程序時，我使用了mysql。 但在部署項目后，我使用了bitnami postgresql的默認值。

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...
                           ^

我不知道數據庫為什么兩次命名數據庫（appName_appName）。

這是完整的終端：

You just installed Django's auth system, which means you don't have any superusers defined.
Would you like to create one now? (yes/no): yesa

我剛剛將appname_appname添加到我的數據庫，它現在工作正常。

抱歉誤導 - 我的錯誤。 我仍然不明白為什么這段代碼沒有被添加到syncdb上的數據庫開始。

但現在一切都很好
