Authentication with facebook in Angularfire - facebook

Question

This is my app.js and i am looking to diplay the user id in the URL but it doesnt work.
$scope.auth = $firebaseSimpleLogin(new Firebase(FBURL));
var userID= $scope.auth.user.id;
$scope.comments = $firebase(new Firebase(FBURL+"//users"+userID+"//Cards"));
$scope.addComment = function(e) {
if (e.keyCode != 13) {
return;
}
if ($scope.auth.user === null) {
alert("You must be logged in to leave a comment");
} else {
$scope.comments.$add({
body: $scope.newComment,
name: $scope.auth.user.name, id: $scope.auth.user.id
});
$scope.newComment = "";
e.preventDefault();
}
}
}
]);
Anyone can help me in figuring it out , what i am doing wrong there?
Thank you.

And from where do you take id ? I don`t see somehow facebook login function.
[Edit] I am playing with that just now as i am new to that too. I think you are missing
$scope.auth.$login('facebook')
This is what is working for me, where from user i am grabbing id, name and so on.
//*** FB login
$scope.fbLogin=function(){
var fbaseRef=new Firebase(FBASE)
var loginObj=$firebaseSimpleLogin(fbaseRef);
console.log("Going fbLogin")
loginObj.$login('facebook').then(function(user){
console.log("FB Login ok",user)
},function(rejection){
console.log("FB Login failes",rejection)
})
}
