angularjs - Factory that serves multiple resource in angular -

i intend return few resource factory, unfortunately failed in case. shows error message entry not function scope.$scope.create.

this working code 1 resource:

     angular.module('entry').factory('entry', function($resource) {           return $resource('/api/entries/:id', { id: '@_id' }, {             update: {               method: 'put'             }           });         });          $scope.create = function() {                      var entry = new entry({                      });                  entry.$save(function() {});        } 

this not working code after adding multiple resource:

 angular.module('entry').factory('entry', function($resource) {       return {             'entrya': $resource('/api/entries/:id', { id: '@_id' }, {                         update: {                           method: 'put'                         }                       }),              'entryb': $resource('/api/entries/:id', { id: '@_id' }, {                         update: {                           method: 'put'                         }                       }),          };     });        $scope.create = function() {                      var entry = new entry({                      });                  entry.entrya.$save(function() {});        }
