Jade/Node 数据库数据未显示

Question

我正在尝试创建一个应用程序来使用 Node 进行限制性预订，但目前我在数据库中的数据没有显示在页面上。这是显示数据的页面的 jade 文件：

extends layout

block content
h1.
    Reservations
ul
    each reservation in reservations
        li= reservation.lastName
        li= reservation.numberOfPeople

这是我的 index.js 文件：

var express = require('express');
var router = express.Router();

/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'Express' });
});

router.get('/reservations', function(req, res) {
    var db = req.db;
    var collection = db.get('freshStart');
    collection.find({},{},function(e,docs){
        res.render('reservations', {
            "reservations" : docs
        });
    });
});

router.get('/makeReservation', function(req, res){
    res.render('makeReservation', { title: 'Make a reservation'});
});

router.post('/makeReservation', function(req, res){
    var db = req.db;

    var lastName = req.body.lastName;
    var numberOfPeople = req.body.numberOfPeople;
    var time = req.body.myTime;
    var date = req.body.myDate;

    var collection = db.get('freshStart');

    collection.insert({
        "lastName" : lastName,
        "numberOfPeople" : numberOfPeople,
        "time" : time,
        "date" : date
    }, function(err, doc) {
        if(err) {
            res.send("There was a problem adding the information to the database", err.toString());
        } else {
            res.redirect("reservations");
        }
    });
});

module.exports = router;

但是当我加载页面时，它只显示标题而没有数据库信息。我在 cmd 中查询了数据，它有两个条目。我做错了什么？

Answer 1

错误是我引用了错误的数据库部分。这是我的代码：

router.get('/reservations', function(req, res) {
    var db = req.db;
    var collection = db.get('freshStart');
    collection.find({},{},function(e,docs){
        res.render('reservations', {
            "reservations" : docs
        });
    });
});

我应该做的是：

router.get('/reservations', function(req, res) {
    var db = req.db;
    var collection = db.get('reservations');
    collection.find({},{},function(e,docs){
        res.render('reservations', {
            "reservations" : docs
        });
    });
});
