Python Django/Cassandra:无法创建超级用户

我正在用Django和Cassandra运行Debian服务器。我无法通过以下命令创建管理员用户：

python manage.py createsuperuser

运行该命令会导致错误：

cassandra.protocol.SyntaxException: <Error from server: code=2000 [Syntax error in CQL query] message="line 1:260 no viable           alternative at input '.' (...auth_user.date_joined FROM auth_user WHERE [auth_user]....)">

完全回溯

Not checking migrations as it is not possible to access/create the django_migrations table.

不检查迁移，因为无法访问/创建django_迁移表。

自我提升。\最终\例外
cassandra.protocol.SyntaxException：

Django Cassandra Engine v1.0.2不支持存储在Cassandra中的用户模型（身份验证模块）

解决方法是为用户模型建立第二个数据库。

我们不能使用：

python manage.py createsuperuser using cassandra

它不适用于默认的django模型

您需要使用外部库来进行相同的操作
