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'
