在 Mongodb 中对单个集合使用多个模式不起作用

Question

我想在 mongodb 中为单个集合使用多个模式，但除了单个模式之外它不存储。其他模式只存储 _id & _v 我的代码有什么问题？ 我试图跟随 http://mongoosejs.com/docs/api.html#index_Mongoose-model

我的模式模型

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

// Reading content Schema 
const contentArticle = new Schema({
  contentCategory: { type: String },  
  contentTitle: { type: String }, 
  body: { type: String }, 
});    

// Quiz Content 
const quizAllArticle =  new Schema({
  quizCategory: { type: String },
  question: { type: String },
  ans: { type: String }
});    

// Article Schema
const topicSchema =  new Schema({
  artId: { type: String },
  postURL: { type: String },
  date: { type: Date, default: Date.now },
  author: { type: String },
  published: {type: String },
  category: { type: String },   
  QuesPapType :{ type: String },  
});

const Content = module.exports = mongoose.model('Contents', contentArticle, 'articles');
const Quiz = module.exports = mongoose.model('Quizs', quizAllArticle, 'articles');
const Topic = module.exports = mongoose.model('TopicContent', topicSchema, 'articles');

其他代码是：

const express = require('express');
const router = express.Router();
const passport = require('passport');
const config = require('../config/database');
const Content = require('../models/art');
const Quiz = require('../models/art');
const Topic = require('../models/art');


router.post('/register',(req, res, next) => { 

    let topic= new Topic({    
        artId : req.body.artId,
        author : req.body.author,
        date : req.body.date,
        published : req.body.published,
        postURL : req.body.postURL,  
        category : req.body.pscCategory,
        QuesPapType : req.body.QuesPapType,       
   });
   console.log(topic);
    topic.save(function(err) {
        if (err) {
            res.json({
                success: false,
                msg: 'failed to register'
            })
        } else {
            res.json({
                success: true,
                msg: 'success to reg article'
            })
        } 
    })
 });

router.post('/reg-content', (req,res,next) => {
    let content= new Content({    
        contentCategory : req.body.contentCategory,
        contentTitle : req.body.contentTitle,
        body : req.body.body,       
    });
    console.log(content);    
    content(function(err) {
        if (err) {
            res.json({success: false, msg: 'failed to register Content'})
        } else {
            res.json({success: true,msg: 'success to reg article'})
        } 
    })
})

router.post('/reg-quiz', (req,res,next) => {
    let quiz= new Quiz({    
        quizCategory : req.body.quizCategory,
        question : req.body.question,
        ans : req.body.ans,       
    });
    console.log(quiz);
    quiz.save(function(err) {
        if (err) {
            res.json({success: false,msg: 'failed to register Content'})
        } else {
            res.json({ success: true, msg: 'success to reg article'})
        } 
    })
})    

 module.exports = router;

主要问题是它只从一个模式保存到数据库，而其他两个模式只保存_id、日期和_v

Answer 2

const Content = mongoose.model('Contents', contentArticle);
const Quiz = mongoose.model('Quizs', quizAllArticle);
const Topic = mongoose.model('TopicContent', topicSchema);
module.exports = {Content, Quiz, Topic};


//import 
const {Content, Quiz, Topic} = require('your schema file');
