I'm starting to get my head around node.js, and I'm trying to figure out how I would do normal MVC stuff. For example, here's a Django view that pulls two sets of records from the database, and sends them to be rendered in a template.
def view(request):
things1 = ThingsOne.objects.all()
things2 = ThingsTwo.objects.all()
render_to_response('template.html, {'things1': things1, 'things2': things2})
What might a similar node.js function look like?
http://boldr.net/mvc-stack-node-js-ejsgi-scylla-mustache is a great little article with a full github example of a MVC pattern using dirfferent Node modules. It also lists alternate modules currently available. It answered this question for me better than http://howtonode.org/ which has some good tuts but I couldn't find anything on MVC there.
The easiest way to do this is with expressjs, which is an MVC framework for Node. Node is just what it says, evented I/O for the web.
The example on the http://expressjs.com should help with the basics but to answer your question directly.
var express = require('express');
var app = express.createServer();
app.get('/whatever', function(req, res) {
Things1.objects.getAll(function(things1) {
Things2.objects.getAll(function(things2) {
var options = { locals: { things1: things1, things2: things2 }};
res.render('thingstemplate.ejs', options); // or thingstemplate.jade or whatever
});
});
});
app.listen('80', ''); // port and optional hostname to bind
