I think I am doing this wrong in backbone, So I have a collection, model and route as such:

Route AisisWriter.Collections.Posts = Backbone.Collection.extend({ model: AisisWriter.Models.Post, // Build the url based on blog id. url: function() { url = '/api/v1/blogs/' + AisisWriter.blog_id + '/posts/' return url; } }); Collection AisisWriter.Routers.Posts = Backbone.Router.extend({ posts: null, routes : { '': 'index' }, initialize: function() { var writer_posts = new AisisWriter.Collections.Posts(); this.posts = writer_posts.fetch(); }, index: function() { console.log(AisisWriter.blog_id, this.posts); } }); Model AisisWriter.Models.Post = Backbone.Model.extend({ initialize: function() {}, getTitle: function() { return this.get('title'); }, getContent: function() { return this.get('content'); }, getTags: function() { return this.get('tag_names'); }, getCategories: function() { return this.get('category_names'); }, getComments: function() { return this.get('comments'); }, });

When the collections index route executes, I get the following back:

Object {readyState: 1, getResponseHeader: function, getAllResponseHeaders: function, setRequestHeader: function, overrideMimeType: function…}

Note: The above is a console output of a non expanded object.

This ... I guess what I would or should expect, accept I assumed I would be getting back my posts object because doing this.posts.getTitle() doesn't work.

So what am I doing wrong in terms of getting my posts object back? Inside this giant object I see a ResponseJSON object that contains my json object - I want that so I can do this.posts.getTitle() ;

I think this is doublicate: Why can I not use this.posts out side the success function?

So as I adviced to you. If you want to get access to this.posts you should just add the observer to your collection in the initialize function:

this.listenTo(this.writer_posts, 'reset', this.test);

Thats I call the Backbone way.

On the other hand it's dificult to understand what you wanna do. For example you're trying to get title from the Collection...

var writer_posts = new AisisWriter.Collections.Posts(); this.posts = writer_posts.fetch();

and then

this.posts.getTitle()

It doesn't work, because it is Collection. And you don't need to create separate methods for getting title, tag and so on from your Model. You can get access to the title directly:

this.model.get('title');

or

this.model.toJSON().title;
