如何使用nodejs加入mongoose中的2个集合

How to join 2 collections in mongoose using nodejs

我想使用 mongoose nodejs 加入两个集合,但我被卡住了,

collection1

collection2

const mongoose = require('mongoose');
const gameSchema = new mongoose.Schema({

    providerName:{
        type: String
    },
    gamesSettings :[{
        type: mongoose.Schema.Types.ObjectId,
        ref: 'games_setting'
    }]
});

module.exports = mongoose.model('gamesDetails', gameSchema);

This is the route : 

router.get('/', async (req, res)=>{


    try {
        const gamesDetails1 = await joinCollection.find();
        res.json(gamesDetails1);
        //res.render('./games/gamesetting', { data: gamesDetails1 });
    } catch (e) {
        res.json({ message: e });
    }

});

我的回复为空。

我不确定我是否正确理解了您的问题,但我认为您需要的是在填充 gameeSetting 的位置执行查询。答案是:

const details = await gamesDetails.find().populate('gamesSettings');
