Question

我尝试使用说明here使用django设置cassandra。

一切正常。迁移时，表格即被创建。但是当我使用python manage.py runserver运行服务器时，它会给我以下错误：

System check identified no issues (0 silenced).

Plz帮助！

Answer 1

这是django-cassandra-engine（1.2.1）的错误。

现在它已在django-cassandra-engine（1.2.2）中修复。

你可以升级你的django-cassandra-engine：

pip install --upgrage django-cassandra-engine

Django与cassandra - cassandra数据库没有架构
