Django 应该连接到 MSSQL

Question

我正在使用 PyCharm、Django 和 MSSQL-Backend-Project。

我正在使用我的 iMac，在本地网络中有一个我想连接的 Microsoft SQL 服务器。

我不确定要使用什么凭据（IP，或者下面指定的主机）。但是，第一次尝试时，我遇到了很多错误。对我来说哪个接缝不是凭据问题，而是安装错误或其他问题。

我已经安装了一个 ne 虚拟环境（我在 google 上找到的建议）。但是还是不行。

任何人都可以帮助我，从哪里开始？

settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    },

    'bnt': {
        'ENGINE': 'sql_server.pyodbc',
        'NAME': 'POS',
        'USER': 'l.bamberg',
        'PASSWORD': '****************',
        'HOST': 'BNTS20005\SQL17STD',

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

错误信息:

Answer 1

按照@EgorWexler 所说继续并安装 libodbc 驱动程序如下：

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
brew tap microsoft/mssql-release https://github.com/Microsoft/homebrew-mssql-release
brew update
HOMEBREW_NO_ENV_FILTERING=1 ACCEPT_EULA=Y brew install msodbcsql17 mssql-tools

到目前为止一切正常。

Django 应该连接到 MSSQL
