如何将microsoft azure SQL server连接到Django webapp

Question

我正在开发一个Django webapp，对于这个应用，我想有一个在线数据库。碰巧我的教职员工允许使用一些微软Azure服务，包括SQL数据库。现在，我想连接一个azuresql数据库到我的Django项目，但是我不能让它工作。我可以通过PyCharm的数据源视图连接到数据库，但是在中使用相同的参数设置.py产生此错误：

根据我的经验，如果您想从Django webapp连接azuresql数据库，最佳实践的简单方法是按照^{}自述安装python包pyodbc&；django-pyodbc-azure并正确配置Django的settings.py文件，如下所示。在

DATABASES = {
    'default': {
        'ENGINE': 'sql_server.pyodbc',
        'NAME': 'mydb',
        'USER': 'user@myserver',
        'PASSWORD': 'password',
        'HOST': 'myserver.database.windows.net',
        'PORT': '',
        'OPTIONS': {
            'driver': 'ODBC Driver 13 for SQL Server',
        },
    },
}
