Question

我正在构建一个webapp，用户可以登录并展示他们的产品（工作室监视器）并向其他用户的产品添加评论。每个用户都有一个带有导航标签的仪表板，他们可以访问他们添加的产品以及他们所做的评论。第一个标签是＆＃39;用户监控＆＃39;标签和第二个标签是用户评论＆＃39;标签。

问题在于，当我制作Monitor.find（{user：req.params.userId}）时，它会在第一个标签中展示用户添加的所有显示器，但在评论标签中，您只会看到仅针对您添加的监视器。我希望审核标签显示用户进行审核的所有显示器（如果显示器是由其他用户添加的，则无关紧要）。

问题简化：

应针对一条路线进行2次查询。第一个是检索用户添加的所有监视器。第二是检索用户进行的所有监视器评论，它还应包括其他用户添加的监视器。
以上数据应显示在仪表板页面的选项卡中。它不必是标签，但数据应该在一个地方。

Mongo模特：

Monitors.js

＆＃13;

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

//Create Monitors Schema
const MonitorSchema = new Schema({
  model: {
    type: String,
    required: true
  },
  company: {
    type: String,
    required: true
  },
  description: {
    type: String,
    required: true
  },
  imgurl: {
    type: String,
  },
  user: {
    type: Schema.Types.ObjectId,
    ref: 'users'
  },
  reviews: [{
    reviewBody: {
      type: String,
      required: true
    },
    reviewDate: {
      type: Date,
      default: Date.now
    },
    reviewUser: {
      type: Schema.Types.ObjectId,
      ref: 'users'
    }
  }],
  date: {
    type: Date,
    default: Date.now
  }
});

mongoose.model('monitors', MonitorSchema)

＆＃13;

user.js的

＆＃13;

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const UserSchema = new Schema({
  username: String,
  password: String,
  email: String
})

mongoose.model('users', UserSchema)

＆＃13;

路线： dashboard.js

＆＃13;

const express = require('express');
const router = express.Router();
const mongoose = require('mongoose');
const async = require('async');

//Load Monitor model
require('../models/Monitors');
const Monitor = mongoose.model('monitors');

//Get Dashboard my monitors tab
router.get('/', function(req, res, next) {
  //Check if user is logged in
  if(req.isAuthenticated()) {
    return next();
  }
  res.redirect('/')
}, (req, res) => {
    Monitor.find({
      user:req.user.id
    })
      .populate('user')
      .populate('reviews.reviewUser')
      .then(monitors => {
        res.render('./dashboard/dashboard', {
          monitors: monitors
        });
      });

})
