Question

我正在尝试使用django-pyodbc版本连接到外部SQL Server Express数据库：this github link但是当我运行manage.py shell检查我是否可以执行时，我一直收到此错误ORM命令

Traceback (most recent call last):
File "manage.py", line 10, in <module>
  execute_from_command_line(sys.argv)
File "/usr/local/lib/python2.7/site-packages/django/core/management/__init__.py", line   443, in execute_from_command_line

  backend = load_backend(connection.settings_dict['ENGINE'])

  self.ops = DatabaseOperations(self)

  super(DatabaseOperations, self).__init__()
  TypeError: __init__() takes exactly 2 arguments (1 given)

我的settings.py有：

DATABASES = {
    'default': {
       'ENGINE': 'sql_server.pyodbc',
       'NAME': 'DBName',
       'HOST': '192.168.29.1',
       'USER': 'user',
       'PASSWORD': 'pswd',
       'PORT': 1433,
    }
}

DATABASE_OPTIONS = {
    'driver': '/usr/local/lib/libtdsodbc.so',
    'dsn': 'FreeTDS',
    'extra_params': "TDS_VERSION=8.0"
}

我完全不知道我应该做什么，所以欢迎所有的想法。基本上我想要的是能够使用我用来与SQL Server数据库连接的小应用程序，同时能够使用普通的DJango ORM命令代替pyodbc连接字符串（和BTW使用pyodbc，我可以连接到没有问题的SQL Server数据库）

在我看来，你在http://code.google.com/p/django-pyodbc/

使用django-pyodbc的旧回购

确保干净地卸载旧版本，然后重新安装

pip uninstall sql-server.pyodbc
pip install git+https://github.com/avidal/django-pyodbc.git

使用带有Django的SQL Server后端
