Django 4.0.3 和 mssql-django 1.1.2 將無法連接到 SQL Server Express 2019

Question

我一直在學習 mssql-django 的本教程https://docs.microsoft.com/en-us/samples/azure-samples/mssql-django-samples/mssql-django-samples/

我的設置是 Django 4.0.3，mssql-django 1.1.2 將無法連接到 Windows 10 上的 SQL Server Express 2019，而 SQL Server Express 2019 在本地運行。

我已經在 GitHub 和 Stack Overflow 上搜索了 mssql-django 配置的示例，但發現的並不多。

我不確定我做錯了什么。

我一直在嘗試的主要事情是押注 NAME、USER 或 HOST 參數不正確，因為其他參數似乎是正確的。

• NAME應該是： avxdb或mxlaptop\\avxdb還是其他？
• USER應該是： pyadmin@mxlaptop還是只是pyadmin ？
• HOST應該是： mxlaptop\SQLEXPRESS 、 mxlaptop\ss2019 、 mxlaptop還是127.0.0.1 ？

DATABASES = {
    'default': {
        "ENGINE": "mssql",
        "NAME": "avxdb",
        "USER": "pyadmin@mxlaptop",
        "PASSWORD": "Python",
        "HOST": "mxlaptop\SQLEXPRESS",
        "PORT": "1433",
        "OPTIONS": {"driver": "ODBC Driver 17 for SQL Server", 
        },
    }
}

編輯：對不起，我沒有發布錯誤：

The above exception was the direct cause of the following exception:

我有一個普通的 Python 腳本，可以通過pyodbc連接到數據庫：

connection = pyodbc.connect('DRIVER={ODBC Driver 17 for SQL Server};'
                                'SERVER=mxlaptop;'
                                'DATABASE=avxdb;'
                                'UID=pyadmin;'
                                'PWD=Python;')

Answer 1

所以事實證明，必須通過 SQL Server 配置啟用 TCP/IP。

此外，這是我發現的正確連接設置：

DATABASES = {
    'default': {
        "ENGINE": "mssql",
        "NAME": "avxdb",
        "USER": "pyadmin",
        "PASSWORD": "Python",
        "HOST": "mxlaptop",
        "PORT": "1433",
        "OPTIONS": {"driver": "ODBC Driver 17 for SQL Server", 
        },
    }
}

所以我有錯誤的USER和錯誤的HOST 。

TCP/IP 必須通過 SQL Server 配置啟用
