inspectdb模型創建Django時出錯

Question

我在Django中使用mssql。 我已經有一個現有的數據庫，並且想要為該數據庫中的表創建Django模型。

我遵循了這本針對inspectdb的django書籍說明。

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

當我輸入命令

python manage.py inspectdb > interface/models.py

我收到以下錯誤

Traceback (most recent call last):
  File "C:\Users\Suman Nepal\Anaconda3\lib\site-packages\sqlserver_ado\dbapi.py", line 547, i

lient 11.0', "Invalid object name 'Attribute'.", None, 0, -2147217865), None)

During handling of the above exception, another exception occurred:

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

Parameters:

我無法弄清楚如何調試此問題。 似乎在最后幾行錯誤中有一些提示

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

但我不知道該改變什么。 有什么建議嗎？

顯然，這是django ms-sql軟件包中存在的未解決問題之一。
