Question

我是python和djanog的新手。

我使用。安装django。

Pip install django

比我安装了Mssql连接器。

pip install django-mssql

使用此命令运行syncdb。

python manage.py syncdb

它显示所有表都已创建，但我没有在sql server management studio中看到任何表。

之后我尝试使用http：// 127.0.0.1:8000/admin打开Admin panal 它给出了错误。

Answer 1

对我来说，我用pip安装了django和django-mssql。 django是版本1.6，django-mssql版本是1.4。

来自文档：

当前版本的django-mssql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或用mercurial克隆它。然后运行以下命令安装

> python setup.py install

现在检查django-mssql的版本

> python
>>> import 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，它也是实例名称。因此，引擎应为sqlserver_ado\instance，实际主机名为[computer name]/IP(172.16.26.51)。

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