Better solution for nested Backbone.js collections

Question

Many of my Backbone models often deal with nested models and collections, so far I\'m using a combination of defaults, parse and toJSON ma

Answer 1

I'v found out that with this approach Supplier's toJSON function will get outdated, so it might be a good idea to do reassemble back it's JSON state from it's, and it's children's data.

ACME.Supplier = Backbone.Model.extend({
    initialize: function(options) {
        this.tags = new ACME.Tags(options.tags);
    },

    parse: function(res) {
        res.tags && this.tags.reset(res.tags);

        return res;
    },

    toJSON: function({
        return _.extend(
            _.pick(this.attributes, 'id', 'attr1', 'attr2'), {
            tags: this.tags.toJSON(),
        });
    })

});
