Question

当我尝试使用Mongoose向Mongo DB保存/创建新文档（用户）时，尽管为所有值提供了正确的DataType，但我得到以下验证错误：

ValidationError：用户验证失败：用户名：路径username是必需的。

我是Node JS和Mongo DB的初学者。因此，我无法理解出了什么问题。

我还添加了以下模块：

猫鼬
Body Parser

请参阅下文了解更多详情：

详细错误：

{
"errors": {
    "username": {
        "message": "Path `username` is required.",
        "name": "ValidatorError",
        "properties": {
            "type": "required",
            "message": "Path `{PATH}` is required.",
            "path": "username"
        },
        "kind": "required",
        "path": "username",
        "$isValidatorError": true
    }
},
"_message": "User validation failed",
"message": "User validation failed: username: Path `username` is required.",
"name": "ValidationError"
}

用户架构/型号：

var mongoose = require("mongoose");

var userSchema = new mongoose.Schema({
firstName: {
    type: String,
    required: true
},
lastName: {
    type: String,
    required: true
},
username: {
    type: String,
    unique: true,
    required: true
},
password: {
    type: String,
    required: true
}
});

mongoose.model("User", userSchema, "users");

用户控制器：

var register = function (req, res) {

console.log("Registering User.");

var firstName = req.body.firstname;
var lastName = req.body.lastname;
var userName = req.body.username;
var password = req.body.password;

User
    .create({
        firstName: firstName,
        lastName: lastName,
        userName: userName,
        password: password
    }, function (err, user) {
        if (err) {
            console.log("Error creating User: ", err);
            res
                .status(400)
                .json(err)
        } else {
            console.log("User Created: ", user);
            res
                .status(201)
                .json(user)
        }
    })
};

我只是不明白，为什么我收到此验证错误。任何人都可以指导我完成这件事。谢谢你的帮助。

你写了一个错字：

User
    .create({
        firstName: firstName,
        lastName: lastName,
        username: userName, // the property is "username" in model
        password: password
    }, function (err, user) {
        if (err) {
            console.log("Error creating User: ", err);
            res
                .status(400)
                .json(err)
        } else {
            console.log("User Created: ", user);
            res
            .status(201)
            .json(user)
        }
    })
};

Node JS + Mongo DB：ValidationError：用户验证失败：用户名：Path`username`是必需的
