Go back and not to refresh the service


#1

I have a problem with the service to come back from a singular view again ajax and refreshes the view I tested with “promises” but I get nothing

.factory('AleatoryPhotos', function($http, $q, $ionicLoading, $state, $ionicPopup) {

var photos = null;
var tags = null;

var retrieve = function() {

	var deferred = $q.defer();


	$http({

		method: 'POST',
		url: restServer,
		data: "funcion=" + "__getRandomImages&token=" + localStorage.getItem("token") + "&userId=" + localStorage.getItem("userId")  ,
		headers: {
			'Content-Type': 'application/x-www-form-urlencoded'
				 }
	}).success(function(data, status, headers, config) {

			if (data.resp == 'denied'){

				deferred.reject();

				localStorage.removeItem("token");

				localStorage.removeItem("userId");

				$state.go('login');

				$ionicPopup.alert({
          template: '<div class="popcontent"><div class="popcolor"><span class="icon-stack"><img width="80" src="img/phone.png"/></span></div><div id="poptitle">logged into another device<div><p>this device has no internet connection, connect it and try it later</p></div>'
        }).then(function(res) {
          
        });



			}else{


				deferred.resolve(data);
				photos = data;
				tags = data;
				
				

			}



	}).error(function(data, status, headers, config) {

		

	});

	return deferred.promise;

}


return {

all: retrieve,

get: function(idPost) {

  return photos[idPost];

},
gettags: function(idPost) {

  return tags[idPost];

}

}

})
