Mongoose: ValidatorError:路径为必填项

Question

我尝试在MongoDB中使用Mongoose进行注册，我得到了这个错误，这可能与我保存在集合中的数据类型有关，这会产生这种冲突。

错误

Error: User validation failed: name: Cast to string failed for value "{...}" at path "name", surname: Path `surname` is required., email: Path `email` is required., birth: Path `birth` is required., password: Path `password` is required.

和我的方案

const mongoose = require('mongoose');
const { Schema, model } = mongoose;
const AutoIncrement = require('mongoose-sequence')(mongoose);
const userSchema = new Schema(
    {
        name: {
            type: String,
            required: 'Please enter your name',
            unique: true,
            trim: true
        },
        surname:{
            type:String,
            required: true,
            trim: true
        },
        email:{
            type:String,
            required: true,
        },
        birth:{
            type:Date,
            required: true  
        },
        password:{
            type:String,
            required: true,
        }
    }, {
        timestamps: true
    }
);
userSchema.plugin(AutoIncrement, {id:'order_seq',inc_field: 'order'});
module.exports = model('User', userSchema);

这就是我执行查询的地方，该错误使我了解到集合并不接受所有字段

const userCtrl = {};

const User = require('../models/User');

userCtrl.createUser = async (req, res) => {
    console.log(req.body);
    try {
        const { username } = req.body;
        console.log(username);
        const newUser = new User({
            name:req.body.name,
            surname:req.body.surname,
            email:req.body.email,
            birth:req.body.birth,
            password:req.body.password,
        });
        await newUser.save();
        res.json('User created');
    } catch (e) {
        console.log(e)
        res.json(e.errmsg);
    }
};

正如错误所说，您没有发布任何数据，这就是为什么这意味着您的req.body对象很可能没有姓氏、电子邮件、出生和密码。

并且您已经将它们指定为Schema中的“必填”字段。这意味着如果字段为空，mongoose将不会创建用户。除非您指定了默认值。

surname: Path `surname` is required., email: Path `email` is required., birth: Path `birth` is required., password: Path `password` is required.
