Backbone.js Model different url for create and update?

Question

lets say I have a Backbone Model and I create an instance of a model like this:

var User = Backbone.Model.extend({ ... });
var John = new User({ name : \'Joh

To abstract dzejkej's solution one level further, you might wrap the Backbone.sync function to query the model for method-specific URLs.

function setDefaultUrlOptionByMethod(syncFunc)
    return function sync (method, model, options) {
        options = options  || {};
        if (!options.url)
            options.url = _.result(model, method + 'Url'); // Let Backbone.sync handle model.url fallback value
        return syncFunc.call(this, method, model, options);
    }
}

Then you could define the model with:

var User = Backbone.Model.extend({
    sync: setDefaultUrlOptionByMethod(Backbone.sync),
    readUrl: '/user/get',
    createUrl: '/user/create',
    updateUrl: '/user/update',
    deleteUrl: '/user/delete'
});
