backbone.nest

Backbone plugin that enables infinitely nested Collections within Models, and advanced data structure.

Basic Concept

Simply use Backbone.Nest instead of Backbone.Model, and use { parse: true } when creating model. The rest is taken care of, set the nest attribute to be the collection you want created, and the nests attribute as a space seperated list of the attributes to be turned into collections.

How to use

var LevelOneModel = Backbone.Nest.extend({
    //stuff
})

var LevelOneModels = Backbone.Collection.extend({
    
    model: LevelOneModel

})

var LevelTwoModel = Backbone.Nest.extend({
    
    nest: LevelOneModels,
    nests: "levelOne"
    //stuff

})

var LevelTwoModels = Backbone.Collection.extend({
    
    model: LevelTwoModel

})

var LevelThreeModel = Backbone.Nest.extend({

    nest: LevelTwoModels,
    nests: "levelTwo"
    //stuff

})

var data = {

    id:0,
    levelTwo:[
        {
            id: 1,
            levelOne:[
                {
                    id:1.1
                },
                {
                    id:1.2
                }
            ]
        },
        {
            id: 2,
            levelOne:[
                {
                    id:2.1
                }
            ]
        },
        {
            id: 3,
            levelOne:[
                {
                    id:3.1
                },
                {
                    id:3.2
                },
                {
                    id:3.3
                }
            ]
        }
    ]

}

var myModel = new LevelThreeModel(data, {parse:true});

myModel.get("levelTwo").get(3).get("levelOne").each(function(mod){
    console.log(mod.get("id")) // 3.1, 3.2, 3.3
})
