Hi everybody

I have a Application where I try to include Firebase. I got it work so far but the way I included the get request in my controller my script just continue without waiting for the data. I would like to convert my request into a request with a promise.

something similar as I used before with normal $http requests:

$http(http_req).then(function mySucces(data) {
// Success
}, function myError(data) {
//something was wrong
});

My current controller looks like this:

.controller('NoticiasCtrl', function(FURL, $scope, $state, $http, $ionicLoading, $rootScope, $firebaseObject, $firebaseArray) {
    $scope.newslist = [];
    $scope.doRefresh = function() {
        //Show loading comment
    	$ionicLoading.show({
        template: '<p>Carregando notícias...</p><ion-spinner></ion-spinner>'
    	});
        var ref = firebase.database().ref('news');
    $scope.newslist = $firebaseArray(ref);

    $ionicLoading.hide();
    $scope.$broadcast('scroll.refreshComplete');

	};

$scope.doRefresh();
})

Basically I want to have the line "var ref = firebase...." with a promise. And if the data is received continue with $scope....

Thank you in advance
