ValidationError：产品验证失败：年龄：需要路径“年龄”。名字：需要路径“名字”

Question

我是 Node.js 的新手，我知道这是一个非常常见的问题，很多人都问过同样的问题。但是您知道在我的情况下没有任何解决方案有效。

请看一下代码，如果我遗漏了什么，请告诉我

谢谢！！

这是与 Mongo db 交互的 node.js 应用程序。

Product.controllers.js

const Products = require("../models/Product.models");

exports.Product_create = function(req, res, next){
    console.log(req.body.Name); //For test only - Here I am getting the values
    console.log(req.body.Age);  //For test only - Here I am getting the values
    let newProduct = new Products()
    {
        first_name = req.body.Name,
        age = req.body.Age
    };
    newProduct.save(function (err) {
        if (err) {
            return next(err);
        }
        res.send('Product Created successfully')
    })
};

exports.test = function(req, res){
    console.log("test controller reached successfully!");
};

Product.models.js

var mongoose = require("mongoose");
var schema = mongoose.Schema;

let ProductSchema = new schema({
    first_name : {type: String, required: true, max: 100},
    age: {type:Number, required: true}
});

//export model
module.exports = mongoose.model("Product", ProductSchema);

这是我发送的请求。

我在console.log(req.body.Name); 和console.log(req.body.Age); 中收到正确的输出。但它仍然没有保存数据。

错误在于您的产品初始化

const Products = require("../models/Product.models");

exports.Product_create = function(req, res, next){
    console.log(req.body.Name); //For test only - Here I am getting the values
    console.log(req.body.Age);  //For test only - Here I am getting the values
    let newProduct = new Products(
    {
        first_name:req.body.Name,
        age:req.body.Age
    });
    newProduct.save(function (err) {
        if (err) {
            return next(err);
        }
        res.send('Product Created successfully')
    })
};

exports.test = function(req, res){
    console.log("test controller reached successfully!");
};

您需要提供first_name and age 作为键值对
