错误（错误页面）

conn = Database.connect(connstr, unicode_results=unicode_results)
django.db.utils.Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnect)')

这是我的数据库连接，我将附加 odbc 连接。请帮助我纠正错误并连接到工作。提前致谢

-1（如果可以的话，还有更多）用于发布代码截图。这是文本，看在上帝的份上：这就是我们剪切和粘贴的原因。
我解决了这个错误。现在它工作正常。谢谢

【解决方案1】：

您需要在 settings.py 文件中的数据库设置下定义您的数据源名称。

DATABASES={
   'default': {
      'OPTIONS':{
         'DRIVER':'FreeTDS',
         'DSN': 'YOUR DSN NAME'
      },
    },
}

错误 20012（严重性 2）：在配置文件中找不到服务器名称。语言环境为“en_US.UTF-8” 语言环境字符集为“UTF-8”，使用默认字符集“UTF-8” 错误 20013（严重性 2）：未知主机名。连接到服务器时出现问题，我收到此错误。请帮我纠正错误。提前致谢。
