Node.js Mongoskin集合迭代> Jade(Node.js Mongoskin collection iteration > Jade)

 我试图通过一个集合来迭代创建一个目录并通过jade向用户显示它，但tableContent每次运行时都是'No Orders'，即使很难，我认为我已正确设置了db。 
 
 “listing.js”用于迭代db集合并将其发送给jade 
 
var express = require('express');
var router = express.Router();

var mongo = require('mongoskin'); 
var db = mongo.db("mongodb://localhost:27017/db", {native_parser:true});

var iterateOrders = function() {
  var tableContent = ''; //TableContent Array
  db.collection('orders').find({}, function(err, result) {
    result.each(function(err, order) {
      tableContent += '<tr>';
      tableContent += '<td>' + this.orderID + '</td>';
      tableContent += '<td>' + this.receiverName + '</td>';
      tableContent += '<td>' + this.receiverAddress + '</td>';
      tableContent += '<td>' + this.receiverEmail + '</td>';
      tableContent += '<td>' + this.order + '</td>';
      tableContent += '</tr>';
      });
    });
    if (tableContent === '') {tableContent = 'No Orders';}
    return tableContent;
  }

router.get('/', function(req, res) {
  res.render('listing', { 
    title: 'Orderlist:', 
    table: iterateOrders() });
});

module.exports = router;
 
 我已经使用“mongo”手动写入数据库 
 
 
 
 db.orders.insert（{ '的orderID' ......恩'}） 
 
 
 我的玉器实现是 
 
block content
  table
    thead
      th #
      th Name
      th Addr
      th Email
      th Order
    tbody= table

I'm trying to iterate trough a collection to create a table of contents and show it to user trough jade, yet tableContent is 'No Orders' every time I run, even tough I think I have set the db correctly.
 
"listing.js" for iterating the db collection and sending it off to jade
 
var express = require('express');
var router = express.Router();

var mongo = require('mongoskin'); 
var db = mongo.db("mongodb://localhost:27017/db", {native_parser:true});

var iterateOrders = function() {
  var tableContent = ''; //TableContent Array
  db.collection('orders').find({}, function(err, result) {
    result.each(function(err, order) {
      tableContent += '<tr>';
      tableContent += '<td>' + this.orderID + '</td>';
      tableContent += '<td>' + this.receiverName + '</td>';
      tableContent += '<td>' + this.receiverAddress + '</td>';
      tableContent += '<td>' + this.receiverEmail + '</td>';
      tableContent += '<td>' + this.order + '</td>';
      tableContent += '</tr>';
      });
    });
    if (tableContent === '') {tableContent = 'No Orders';}
    return tableContent;
  }

router.get('/', function(req, res) {
  res.render('listing', { 
    title: 'Orderlist:', 
    table: iterateOrders() });
});

module.exports = router;
 
I have written to the database manually using "mongo"
 
 
 
db.orders.insert({'orderID'...en'})
 
 
My jade implementation is
 
block content
  table
    thead
      th #
      th Name
      th Addr
      th Email
      th Order
    tbody= table
