  <pre><code>.controller('newPresentacionController', function ($scope, Presentacion, Categoria) {
               $scope.categorias ={};
               var vm = this;
               var presentacionData = {};

                       categorias_id: $scope.categorias_id,
                       longitude: self.myMarker.position.lng(),
                       latitud: self.myMarker.position.lat(),
                       zoom: 13
                   };
                   Presentacion.crearPresentacion(presentacionData).success(function (datos) {
  
                   });
               };
  }

  <pre><code>(function () {
      angular.module('presentacionService', [])
          .factory('Presentacion', function ($http) {
              var presentacionFactory = {};
              presentacionFactory.crearPresentacion = function(presenData) {
                  console.log(presenData);
                  return $http.post('/api/presentaciones/' + presenData);
              };
              return presentacionFactory;
          });
  })();
