django - 使用 Django pyodbc SQLSERVER 问题

Question

我正在尝试将 django 与 sqlserver 连接。我已经安装了 python odbc 和 django-odbc。

我的数据库配置 (settings.py)

DATABASES = {
    'default': {
        'ENGINE': 'sql_server.pyodbc', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'EDAS',                      # Or path to database file if using sqlite3.
        'USER': 'sa',                      # Not used with sqlite3.
        'PASSWORD': '1324',                  # Not used with sqlite3.
        'HOST': 'DBIO01-HP',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '1433'                      # Set to empty string for default. Not used with sqlite3.
    }
}

但是，当我尝试运行服务器时出现此错误:

C:\edas>python manage.py runserver

Validating models...

    elif 'collation' in settings.DATABASE_OPTIONS:
  File "C:\Python27\lib\site-packages\django\utils\functional.py", line 185, in inner
    return func(self._wrapped, *args)
AttributeError: 'Settings' object has no attribute 'DATABASE_OPTIONS'

有人可以帮我弄清楚如何解决它吗？

通过切换到 Michael Baltaks 提到的分支，我更进一步。我使用以下命令卸载旧的不兼容版本:

$ pip uninstall sql-server.pyodbc

然后安装 git-hub 版本:

$ pip install https://github.com/avidal/django-pyodbc/archive/django-1.4.zip

然而，这并没有让我一路工作。我现在收到以下错误:

pyodbc.Error: ('00000', '[00000] [iODBC][Driver Manager]dlopen({FreeTDS}, 6): image not found (0) (SQLDriverConnect)')
