“How” to save an entire collection in Backbone.js - Backbone.sync or jQuery.ajax?

Question

I am well aware it can be done and I\'ve looked at quite a few places (including: Best practice for saving an entire collection?). But I\'m still not clear \"exactly how\"

Answer 1

I would try something like:

var CollectionSync = function(method, model, [options]) {
    // do similar things to Backbone.sync
}

var MyCollection = Backbone.Collection.extend({
    sync: CollectionSync,
    model: MyModel,
    getChanged: function() {
        // return a list of models that have changed by checking hasChanged()
    },
    save: function(attributes, options) {
        // do similar things as Model.save
    }
});
