Question

我是一名努力使我的mongodb对象显示在浏览器中的开发人员。我认为我的查询运行正常，但是由于某些原因，网页上的forEach循环未显示我的数据。

这是我的app.js代码：

const   express = require('express'),
        methodOverride = require('method-override'),
        bodyParser = require('body-parser'),
        mongoose  = require('mongoose'),
        expressSanitizer = require('express-sanitizer'),
        app = express();

mongoose.connect('mongodb://localhost:27017/sale', {useNewUrlParser: true});
app.set('view engine', 'ejs');
app.use(express.static('public'));
app.use(bodyParser.urlencoded({extended: true}));
app.use(expressSanitizer());
app.use(methodOverride('_method'));

//mongoose model config
var saleSchema = new mongoose.Schema({
    name: String,
    addrLine1 : String,
    addrLine2 : String,
    City: String,
    State: String,
    Date: {type: Date},
    saleCategories: {type: String}
});

var Sale = mongoose.model('Sale', saleSchema);

var categorySchema = new mongoose.Schema({
   type: {type: String} 
});

var Category = mongoose.model('Category', categorySchema);

//RESTful Routes
app.get('/', (req, res) => {
   res.redirect('/sales');
});

//Index
app.get('/sales', (req, res) => {
    Sale.find({}, (err, sales) => {
        if(err){
            console.log("ERROR ON INDEX!");
        } else {
            res.render('index', {sales: sales});
        }
    });
});

这是我的ejs文件：

<% include partials/header %>

<h1>Sales Index page</h1>
<% sales.forEach((sale) => { %>
<p><%= sale.name %></p>
<% }); %>

<% include partials/footer %>

这是我的mongodb的销售合集：

> db.sale.find({}, {name: 1, _id: 0})
{ "name" : "Craig Test Sale" }
{ "name" : "McCauley Test Sale" }

我希望我的ejs文件列出销售集合中每个项目的名称字段，但是除了页眉，页脚和<h1>外，我什么也没得到。

如何在页面上显示mongodb查询结果？
