python - 在Django-mssql中运行syncdb时SQL插入编译器错误

Question

这是在 Microsoft SQL Server 2005 上。 Python 2.7。 Django 1.4

Django-MSSQL 已安装并连接到数据库。

我可以读取表格，但不能插入或更新它们。通过 django 在空数据库上的教程，我得到了这一点:

# Save the object into the database. You have to call save() explicitly.
>>> p.save()

调用 save() 后我得到这个 error message (也有报道):

Creating tables ...

更新:我回滚到 Django 1.3，这个错误就消失了。我怀疑 Django 在 1.4 中处理用户和身份验证的方式发生了变化。当我有机会时，我会查看源代码并尝试修补。

django-mssql v1.1 添加了对 Django 1.4 的支持

pip install django-mssql>=1.1
