在Django中处理多个数据库

I am developing a web-application in Django using MySQL database. Now, I need to connect to an internal SQL Server Database and update only 1 table ClientDetails

这是我的数据库配置:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'database_name',
        'USER': 'root',
        'PASSWORD': '',
        'HOST': '127.0.0.1',
        'PORT': '3306',
        'OPTIONS': {
            'init_command': "SET sql_mode='STRICT_TRANS_TABLES'"
        }
    },
    'internal': {        
        'ENGINE': 'sql_server.pyodbc',
        'NAME': 'client_database',
        'USER': 'client',
        'PASSWORD': 'password',
        'HOST': 'Database_Internal'        
    }
}

How do I write to the table ClientDetails in the 2nd Database?
