MeteorJS: Routing with Backbone.js

MeteorJS: Routing with Backbone.js

Problem

I'm trying to implement a Router with BackboneJS in my MeteorJS app. When you call the url 'localhost:3000/1' my router stores the id '1' in the session. After that I want to take the id from the session and use it in my query to select an object from my collection. But whenever I try to use a session attribute in my query it fails. So I want to know if there is a better way for routing with MeteorJS and why my query fails.

test.js

Meteor.subscribe("test");

Test = new Meteor.Collection("test");

Session.set("id", null);

Template.hello.test = function () {
  var avg = 0, total = 0, cursor = Test.find(), count = cursor.count();
  cursor.forEach(function(e)
  {
    total += e.number;
  });
  avg = total / count;

  var session_id = Session.get("id");

  var test = Test.findOne({id: session_id}); //doesn't work
  if (test) {
    test.avg = avg;
  }

  return test;
}

//ROUTER
var TestRouter = Backbone.Router.extend({
  routes: {
    ":get_id":    "get_id" 
  },
  get_id: function (get_id) {
    Session.set("id", get_id);
    console.log(get_id);
  }
});

Router = new TestRouter;

Meteor.startup(function () {
  Backbone.history.start({pushState: true});
});

test.html


  test
  {{> hello}}


model.js

Test = new Meteor.Collection("test");

Test.remove({});

if (Test.find().count()

Solution

I debug the code and find out that 'id' in collection is an integer, while session_id is a string. You need parseInt to convert session_id.

I use page.js for routing, which is "Micro client-side router inspired by the Express router", an excellent work from "TJ Holowaychuk".

I strongly suggest it, since Meteor and backbone have some feature collisions in Model/Collection & View/Template.
