Question

我正在使用django和mssql。我已经有了一个现有的数据库，并希望为该数据库中的表创建django模型。

我遵循了这个关于inspectdb的django book指令。

http://django-book.readthedocs.io/en/latest/chapter18.html

当我输入命令

时

python manage.py inspectdb > interface/models.py

我收到以下错误

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

Parameters:

我无法弄清楚如何调试此问题。似乎在最后一行错误上有一些提示

Command:
SELECT * FROM [Attribute] where 1=0
Parameters:
[]

但我不知道该改变什么。有什么建议吗？

显然它是django ms-sql包中存在的一个未解决的问题。

如果有人遇到同样的问题，请制作自己的模型或look at the workaround recommended at the end of this issue
