Restservice factory that works with Apigility and Restangular

RestService.js

angular.module('appName').factory('RestService', ['Restangular', '$q', function(Restangular, $q){
    var service;

    return {
        setService: function($serviceName){

            }, function(error){
                serviceDeferred.reject(error);
            });
            return serviceDeferred.promise;
        },

Added missing functions to make a complete RestfulService

Hi, are you sure this works? cause I think that apigility gives lots of issues with restangular, I have added myself this to the configuration in order to make my apigility service work (fetchAll)
RestangularProvider.setBaseUrl('http://' + serverAddress + '/api/');

// will Restangularize Apigility responses
// @see https://github.com/mgonto/restangular#my-response-is-actually-wrapped-with-some-metadata-how-do-i-get-the-data-in-that-case
RestangularProvider.addResponseInterceptor(
        function (data, operation, what)
        {
            var extractedData = [];
            if (operation == 'getList')
            {
                for (var property in data) 
                {
                    if (data.hasOwnProperty(property)) 
                    {
                        extractedData.push(data[property]);
                    }
                }

                extractedData.meta = {
                    _links : data._links || {},
                    page_count : data.page_count || 0,
                    page_size : data.page_size || 0,
                    total_items : data.total_items || 0
                };

            }

            return extractedData;
        }
);

// Restangular will send a body on remove.  Apigility does'nt like that so remove the body
RestangularProvider.addRequestInterceptor(
        function (element, operation)
        {
            if (operation === 'remove')
            {
                return null;
            }

            return element;
        }
);

// this casts the self link back to restangular so it knows how to reference itself
RestangularProvider.setRestangularFields({
    selfLink : '_links.self.href',
    cache : true // this will cache most GET requests locally
});

still don't get to work the "PUT" counterpart, any ideas??
