我正在尝试按日期降序查询结果。我的应用程序中的日期变量称为approvaldate。
myroute.js
'use strict';
var express = require('express');
var Ad = require('../models/ad.model.js');
var moment = require('moment');
var router = express.Router();
/* GET home page. */
router.get('/', function (req, res) {
Ad.find({ adstatus: 'approved' }).sort({ approvaldate: -1 }).exec(function (err, approvedads) {
if (err) {
console.log(err);
}
else {
approvedads.adsince = moment(approvedads.creationdate).fromNow();
console.log(approvedads);
res.render('index', { approvedads: approvedads});
}
});
});
module.exports = router;
下面是我在console.log(approvedads);被执行后得到的结果。请注意，返回的结果是如何在ad上加上heading的{{1}}和approvaldate并在[ { adstatus: 'approved',
imgdest: [ 'img1.jpg', 'img2.jpg', 'img1.jpg', 'img2.jpg' ],
