javascript - 添加记录时出现 ValidatorError

Question

我正在尝试向我的 mongodb 数据库添加一条记录。我确信我提供了正确的值，尽管 mongoose 认为它们丢失了。这是我的架构 -

var mongoose = require('mongoose');

    var SocketUserSchema = new mongoose.Schema({
        name: String,
        username: {
            type: String,
            unique: true,
            required: true
        },
        password: {
            type: String,
            required: true
        },
        devices: [{
            name: String,
            platform: String
        }],
        first_ip: {
            type: String,
            default: "0.0.0.0"
        },
        last_login_ip: {
            type: String,
            default: "0.0.0.0"
        },
        added_at: {
            type: Date,
            default: Date.now
        },
    });

    module.exports = mongoose.model('SocketUser', SocketUserSchema);

这是我的创建代码片段 -

console.log('registered triggered ' + data);
/*var jsonData = data;
jsonData.first_ip = clientIpAddress;
jsonData.last_login_ip = clientIpAddress;*/
var user = new SocketUser({
username: data.username,
     password: data.password,
     devices: data.devices,
     first_ip: clientIpAddress,
     last_login_ip: clientIpAddress
});

SocketUser.create(user, function(err, post) {
    if (err) {
        console.log('error',err);
    } else {
        console.log('success');
    }
});

这是我发送的示例用户数据 -

{
  "username": "nexus",
  "password": "noob",
  "devices": [
    {
      "name": "Nexus",
      "platform": "android"
    }
  ]
}

这是我得到的错误 -

{
  "message": "SocketUser validation failed",
  "name": "ValidationError",
  "errors": {
    "username": {
      "properties": {
        "type": "required",
        "message": "Path `{PATH}` is required.",
        "path": "username"
      },
      "message": "Path `username` is required.",
      "name": "ValidatorError",
      "kind": "required",
      "path": "username"
    },
    "password": {
      "properties": {
        "type": "required",
        "message": "Path `{PATH}` is required.",
        "path": "password"
      },
      "message": "Path `password` is required.",
      "name": "ValidatorError",
      "kind": "required",
      "path": "password"
    }
  }
}

如您所见，用户名和密码这两个字段都在数据中，但它仍然给出错误。我试过将数据 json 直接发送到 Create 方法，也尝试过保存方法。两者都给出相同的错误。我在这里遗漏了什么吗？

更新:
在将记录添加到数据库之前，我尝试验证记录，但它给出了同样的错误 -

user.validate(function(err) {
    if (err) {
        console.log("error "+err.message+"\nFull error: "+JSON.stringify(err));
    }
    else {
    }
});

registered triggered {"username":"nexus","password":"noob","devices":[{"name":"N
exus","platform":"android"}]}
error SocketUser validation failed
Full error: {"message":"SocketUser validation failed","name":"ValidationError","
errors":{"password":{"properties":{"type":"required","message":"Path `{PATH}` is
 required.","path":"password"},"message":"Path `password` is required.","name":"
ValidatorError","kind":"required","path":"password"},"username":{"properties":{"
type":"required","message":"Path `{PATH}` is required.","path":"username"},"mess
age":"Path `username` is required.","name":"ValidatorError","kind":"required","p
ath":"username"}}}

我找不到用户名和密码的问题。出于显而易见的原因，我希望将这些字段作为必填字段。

我发现了问题，我检查了我是否正确获取了 data.username 和 data.password。它们导致 undefined。然后我意识到数据实际上是一个字符串，而不是一个对象。所以我把它解析成 json 然后让它工作。这是执行此操作的代码，以防有人遇到同样的问题 -

data = JSON.parse(data);
