Follow @neutralthoughtsBackbone collections are simply an ordered set of models. Such that it can be used in situations such as;
Typically your collection will only use one type of model but models themselves are not limited to a type of collection;
Here is a generic Model/Collection example.
var Song = Backbone.Model.extend({
initialize: function(){
console.log("Music is the answer");
}
});
var Album = Backbone.Collection.extend({
model: Song
});
Now we are going to populate a creation with some useful data.
var Song = Backbone.Model.extend({
defaults: {
name: "Not specified",
artist: "Not specified"
},
initialize: function(){
console.log("Music is the answer");
}
});
var Album = Backbone.Collection.extend({
model: Song
});
var song1 = new Song({ name: "How Bizarre", artist: "OMC" });
var song2 = new Song({ name: "Sexual Healing", artist: "Marvin Gaye" });
var song3 = new Song({ name: "Talk It Over In Bed", artist: "OMC" });
var myAlbum = new Album([ song1, song2, song3]);
console.log( myAlbum.models ); // [song1, song2, song3]
