我有包含 2 个唯一字段(电子邮件和用户名)的用户架构，当我尝试使用重复字段创建新用户时，出现该错误
{
"error": {
"code": 11000,
"index": 0,
"errmsg": "E11000 duplicate key error collection: InstaClone.users index: email_1 dup key: { : \"<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="f496959d9095869d9bda8195b49399959d98da979b99" rel="noreferrer noopener nofollow">[email protected]</a>\" }",

}
}
}
如何获得重复的归档名称？我看到的唯一方法是解析 errmsg 字段。也许有人知道更好的方法？
最佳答案
要自定义从 mongoose 唯一验证返回的错误，您可以使用名为:mongoose-beautiful-unique-validation
https://www.npmjs.com/package/mongoose-beautiful-unique-validation
关于javascript - Mongoose - 检测重复字段，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42974375/
