带有 MSSQL 的 Django 给出错误：'DatabaseWrapper' 对象没有属性'Database'

Question

我是 python 和 djanog 的新手。

我使用 django 安装。

Pip install django

比我安装 Mssql 连接器。

pip install django-mssql

比我使用这个命令运行syncdb。

python manage.py syncdb

它显示所有表都已创建，但我在 sql server management studio 中没有看到任何表。

之后我尝试使用 http://127.0.0.1:8000/admin 打开管理面板 它给出了错误。

错误

Answer 1

对我来说，我使用 pip 安装了 django 和 django-mssql。 django 是 1.6 版，django-mssql 是 1.4 版。

来自文档：

django-mssql 当前版本支持 Django 1.6。

django-mssql 1.4 支持 Django 1.4 和 1.5。

我解决了从源代码安装 django-mssql 的问题。从 bitbucket 下载源代码。 https://bitbucket.org/Manfre/django-mssql/get/default.zip 或使用 mercurial 克隆它。 然后运行以下命令进行安装

> python setup.py install

现在检查 django-mssql 的版本

> 蟒蛇 >>> 导入 sqlserver_ado >>> sqlserver_ado.__version__ u'1.5a'

Answer 2

我不太了解 Django，但是，我知道 SQL Server。从下面的连接文件：

'default': {
'NAME': 'dbexp',
'ENGINE': 'sqlserver_ado',
'HOST': '172.16.26.51\instance',
'USER': '****',
'PASSWORD': '******',
}

我假设dbexp 是数据库名称，sqlserver_ado 是数据库引擎名称，也是实例名称。所以，引擎应该是sqlserver_ado\instance，而实际的主机名是[computer name]/IP(172.16.26.51)。
