Express的节点js无法加载mongodb数据库内容

Question

Trying to learn MongoDB for Node.js

I've my app.js :

 var express = require('express'), app = express(), engines = require('consolidate'), MongoClient = require('mongodb').MongoClient, assert = require('assert'); app.engine('html', engines.nunjucks); app.set('view engine', 'html'); app.set('views', __dirname + '/views'); MongoClient.connect('mongodb://localhost:27017/startup', function(err, db) { assert.equal(null, err); console.log("Successfully connected to MongoDB."); app.get('/', function(req, res) { db.collection('startup').find({}).toArray(function(err, docs) { res.render('startup', { 'name': docs }); console.log(docs); }); }); app.use(function(req, res) { res.sendStatus(404); }); var server = app.listen(3000, function() { var port = server.address().port; console.log('Express server listening on port %s.', port); }); }); 

There're documents in the startup collection as well:

And the template file is:

 <h1>startups</h1> {% for s in startup %} <li><a href="https://www.google.com/search?q={{ s.name }}">{{ s.name }}, {{ s.Founded }}</a> </li> {% else %} <li>No startups found.</li> {% endfor %} 

However, the result says:

Can someone point me, where am I wrong?

Answer 1

You're passing the startups collection as a name property, but in a template you try to access it with startup identifier for some reason.

Change either and you're good.
