Question

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

当我在本地开发应用程序时，我使用了mysql。但在部署项目后，我使用了bitnami postgresql的默认值。

现在我收到以下错误：

django.db.utils.DatabaseError: relation "appName_appName" does not exist
LINE 1: SELECT (1) AS "a" FROM "appName_appName" WHERE "appName_a...
                           ^

我不知道数据库为什么两次命名数据库（appName_appName）。

这是完整的终端：

bitnami@dom:/opt/bitnami/projects/Project$ sudo python manage.py syncdb

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

我刚刚将appname_appname添加到我的数据库中，现在工作正常。

抱歉误导 - 我的错误。我仍然不明白为什么这段代码没有被添加到syncdb上的数据库中开始。

但现在一切都很顺利

将项目部署到bitnami后，django postgresql数据库中的Relational DatabaseError
