sql-server - 使用 odbc 将 django 连接到 MS SQL Server

问题描述

尝试执行 manage.py runserver 时出现错误。我已经为 sql server 安装了 django-pyodbc 和 odbc 驱动程序 17。我需要在项目的某处导入 pyodbc 吗？一般来说，我对 django 和 python 很陌生，但我想使用 ms sql server 而不是 sqlite。这是 manage.py 中的代码：

DATABASES = {
    'default': {
        'ENGINE': 'sql_server.pyodbc',
        'NAME': 'database',
        'HOST': 'localhost',
        'USER': 'user',
        'PASSWORD': 'password',

        'OPTIONS': {'ODBC Driver 17 for SQL Server',
                    }
    }
}

这是错误：

解决方案

将您的选项更改为关注。错误可能是由 pyodbc 库的字符串解析功能引起的。

'OPTIONS': {
'driver': 'ODBC Driver 17 for SQL Server',
}

或者

‘OPTIONS’: {“ODBC Driver 17 for SQL Server”, }
