node.js - 在猫鼬中投射到嵌入式失败错误

问题描述

我一直在寻找许多来源解决我的问题，但不幸的是我找不到答案。你能帮我吗。

其中有带有架构的文件。

const mongoose = require('mongoose');
const config = require('../config/database');

const analogueNumberSchema = new mongoose.Schema({
    analogueName: String,
    analogueNum: String
});

const detailSchema = new mongoose.Schema({
    detailName: String,
    originalNumber: [String],
    analogueNumber: [analogueNumberSchema],
    note: String,
    picture: String
});

const modelModificationsSchema = new mongoose.Schema({
    modelModificationName: String,
    modelDetails: {
        engine: [detailSchema],
        transmission: [detailSchema],
        frontAxle: [detailSchema],
        rearAxle: [detailSchema],
        breakes: [detailSchema],
        electrics: [detailSchema]
    }
});

const markModelsSchema = new mongoose.Schema({
    markModelName: String,
    modelModifications: [modelModificationsSchema]
});

const carsSchema = new mongoose.Schema({
    markName: String,
    markModels: [markModelsSchema]
});

const Car = module.exports = new mongoose.model('Car', carsSchema);

module.exports.addCar = function (newCar, callback) {
    newCar.save(callback);
};

这是路由器代码：

router.post('/post', (req, res, next) => {
let newCar = new Car({
    markName: req.body.markName,
    markModels: [{
        markModelName: req.body.markModelName,
        modelModifications: [{
            modelModificationName: req.body.modelModificationName,
            modelDetails: [{
                engine: [{
                    detailName: req.body.detailName,
                    originalNumber: req.body.originalNumber.split(","),
                    analogueNumber: [{
                        analogueName: req.body.analogueName,
                        analogueNum: req.body.analogueNumber
                    }],
                    note: req.body.note,
                    picture: req.body.picture
                }],
                transmission: [{
                    detailName: req.body.detailName,
                    originalNumber: req.body.originalNumber.split(","),
                    analogueNumber: [{
                        analogueName: req.body.analogueName,
                        analogueNum: req.body.analogueNumber
                    }],
                    note: req.body.note,
                    picture: req.body.picture
                }],
                frontAxle: [{
                    detailName: req.body.detailName,
                    originalNumber: req.body.originalNumber.split(","),
                    analogueNumber: [{
                        analogueName: req.body.analogueName,
                        analogueNum: req.body.analogueNumber
                    }],
                    note: req.body.note,
                    picture: req.body.picture
                }],
                rearAxle: [{
                    detailName: req.body.detailName,
                    originalNumber: req.body.originalNumber.split(","),
                    analogueNumber: [{
                        analogueName: req.body.analogueName,
                        analogueNum: req.body.analogueNumber
                    }],
                    note: req.body.note,
                    picture: req.body.picture
                }],
                breakes: [{
                    detailName: req.body.detailName,
                    originalNumber: req.body.originalNumber.split(","),
                    analogueNumber: [{
                        analogueName: req.body.analogueName,
                        analogueNum: req.body.analogueNumber
                    }],
                    note: req.body.note,
                    picture: req.body.picture
                }],
                electrics: [{
                    detailName: req.body.detailName,
                    originalNumber: req.body.originalNumber.split(","),
                    analogueNumber: [{
                        analogueName: req.body.analogueName,
                        analogueNum: req.body.analogueNumber
                    }],
                    note: req.body.note,
                    picture: req.body.picture
                }]
            }]
        }]
    }]
});

Car.addCar(newCar, (err, car) => {
    if (err) {
        res.json({success: false, msg: 'failed to add new car'});
        console.log(err);
    } else {
        res.json({success: true, msg: 'new car added'});
    }
});
});

这是“邮递员”中的后查询代码

        }]
    }]
}]
 }

并且有错误消息：

'值“[ { engine: [ [Object] ],\n
传输: [ [Object] ],\n frontAxle: [ [Object] ],\n后轴: [ [Object] ], 'Cast to Embedded 失败
,\n中断：[ [Object] ]，\n 电气：[ [Object] ] } ]" 在路径 "modelDetails"'，名称：'CastError'，stringValue：'"[ { engine: [ [Object] ]，\n 传输: [ [Object] ],\n 前轴: [ [Object] ],\n 后轴: [ [Object] ],\n 刹车: [ [Object] ],\n 电气: [ [Object] ] } ]"' , kind: 'Embedded', value: [Array], path: 'modelDetails', reason: [Object] } }, _message: '汽车验证失败', name: 'ValidationError' }

我非常感谢您的帮助。谢谢！

解决方案

最后我有我的问题的答案。roter 代码有错误。您只需要定义属性而不定义结构。这是代码

router.post('/post', (req, res, next) => {
let newCar = new Car({
    markName: req.body.markName,
    markModels: req.body.markModels,
    modelModificationName: req.body.modelModificationName,
    modelDetails: req.body.modelDetails,
    engine: req.body.engine,
    transmission: req.body.transmission,
    frontAxle: req.body.frontAxle,
    rearAxle: req.body.rearAxle,
    breakes: req.body.breakes,
    electrics: req.body.electrics,
    detailName: req.body.detailName,
    originalNumber: req.body.originalNumber,
    analogueNumber: req.body.analogueNumber,
    note: req.body.note,
    picture: req.body.picture,
    analogueName: req.body.analogueName,
    analogueNum: req.body.analogueNum
});

Car.addCar(newCar, (err, car) => {
    if (err) {
        res.json({ success: false, msg: 'failed to add new car' });
        console.log(err);

    } else {
        res.json({ success: true, msg: 'new car added' });
    }
});

}); 如果有人感兴趣，谢谢。抱歉文字错误））
