What could be the reason for the reset event of my Backbone Collection not being triggered?

After completing the Railscast tutorial successfully, I decided to work on a quick prototype to test the viability of Backbone. Unfortunately, I seem to have made a mistake somewhere as things are not working as expected. I am using Backbone 1.

View

class Shsh.Views.AssetsIndex extends Backbone.View

template: JST['assets/index']

initialize: ->
  @collection.on('reset', @render, this)

render: ->
  $(@el).html(@template(assets: @collection))
  console.log('rendered')
  this

Router

class Shsh.Routers.Assets extends Backbone.Router
  routes: 
    '': 'index'

  initialize: ->
    @collection = new Shsh.Collections.Assets()
    @collection.fetch({reset: true})

  index: ->
    view = new Shsh.Views.AssetsIndex(collection: @collection)
    $('#container').html(view.render().el)

Although the view is rendered correctly, the length of @assets is returning as 0. Strangely, when I repeat the steps in the console and re-render the view, it shows the correct length. Any ideas on what could be causing this issue?

EDIT:

I do have a collection and model in place. The code included here is all boilerplate generated by Backbone On Rails.

Answer №1

It appears that you are calling fetch() too soon, specifically during router creation. It would be more appropriate to call it within the specific route code instead. The current implementation may result in fetch and reset completing before the route is triggered, causing you to start listening to the reset event after it has already been fired.

Answer №2

Oops, I made a mistake. The word "Initialize" is misspelled in the Shsh.Views.AssetIndex file.
