    backbone-deep-model

    Improved support for models with nested attributes.

    Allows you to get and set nested attributes with path syntax, e.g. user.type.

    Triggers change events for changes on nested attributes.

    Dependencies

    Backbone >= 0.9.10

    Installation

    1. Include Backbone and it's dependencies in your page/app.
    2. Include distribution/deep-model.min.js

    Usage

    Then just have your models extend from Backbone.DeepModel instead of Backbone.Model.

    Example code:

    //Create models with nested attributes
    var model = new Backbone.DeepModel({
        id: 123,
        user: {
            type: 'Spy',
            name: {
                first: 'Sterling',
                last: 'Archer'
            }
        },
        otherSpies: [
            { name: 'Lana' },
            { name: 'Cyrril' }
        ]
    });
    
    //You can bind to change events on nested attributes
    model.bind('change:user.name.first', function(model, val) {
        console.log(val);
    });
    
    //Wildcards are supported
    model.bind('change:user.*', function() {});
    
    //Use set with a path name for nested attributes
    //NOTE you must you quotation marks around the key name when using a path
    model.set({
        'user.name.first': 'Lana',
        'user.name.last':  'Kang'
    });
    
    //Use get() with path names so you can create getters later
    console.log(model.get('user.type'));    // 'Spy'
    
    //You can use index notation to fetch from arrays
    console.log(model.get('otherSpies.0.name')) //'Lana'
