angularjs - How to manipulate data from ngResource query() before returning it? -

i'm trying comprehend how can modify data $resource.query() returns - turned out - not promise $q empty object/array filled when async call done.

i defined service i'd modify data came $resource (filter precise), nothing gets filtered. whole array back.

i'm sure there trivial thing i'm missing here. in advance.

here's service (employee $resource):

  factory('report', ['employee',         function(employee) {              var query = function(id, cb) {                 return employee.query({}, function(data) {                     return cb(data, id);                 });             };              var findbymanager = function(employees, employeeid) {                 return employees.filter(function(element) {                     console.log(element);                     return employeeid === element.managerid;                 });              };              return {                 query: function(employee) {                     return query(employee.employeeid, findbymanager);                 }             };          }   ]); 

edit

by ippi suggestion tried accessing underlying promise:

var query = function(id) {             return employee.query().$promise                 .then(function(data) {                     return findbymanager(data, id);                 });         };  return {     query: query, } 

in controller:

$scope.employees = report.query(id); 

but returns object instead of array.

i'm not sure if complete answer looking for, should help:

employee.query({...}) not promise can access raw $http promise this:

employee.query({...}).$promise.then(function(result){     console.log(result); }); 

($resource wrapper around $http.)

and if don't mind me saying so, idea of filtering resources on client-side second retrieve them sound if works against idea api-resources begin with. requesting subset of "employees" sure sounds api-feature , should implemented on server-side. i'd you'd want call resource like:

employee.query({ managerid: employee.employeeid });

edit:

alright, scrapped report-factory (sorry!) , ended with:

// controller $scope.id = 1; // or something... $scope.employees = employee.query();  // html <tr ng-repeat="employee in employees | filter: {employeeid: id} : true | orderby:id"> 

it seems acceptable answer well: https://stackoverflow.com/a/28907040/1497533
