Exclude model properties when syncing (Backbone.js)

Question

Is there a way to exclude certain property from my model when I sync?

For example, I keep in my model information about some view state. Let\'s say I have a picker m

In Underscore 1.3.3 they added pick and in 1.4.0 they added omit which can be used very simply to override your model's toJSON function to whitelist attributes with _.pick or blacklist attributes with _.omit.

And since toJSON is used by the sync command for passing the data to the server I think this is a good solution as long as you do not want these fields wherever else you use toJSON.

Backbone.Model.extend({
    blacklist: ['selected',],
    toJSON: function(options) {
        return _.omit(this.attributes, this.blacklist);
    },
});
