Firebase logout show Permission denied error.

Question

So whenever I logout from Firebase, I got coupled

Error: permission_denied: Client doesn't have permission to access the desired data.

I understand it is because login session is terminated, some of my objects cannot access firebase data any more. But how can I disconnect this objects before logout?

For logout button in one of my Ionic View, it just call a firebase service:

function logout() {
      auth.$unauth();
      getCurrentUser();
};
function getCurrentUser() {
        var authData = auth.$getAuth();
        if (authData) {
            $rootScope.userId = authData.uid;
            $rootScope.currentUser = $firebaseObject(authRef.child("users").child(authData.uid));
            return $rootScope.currentUser;
        } else {
          console.log("User is not login!");
          $rootScope.userId = null;
          $location.path("/auth/signin");
          if ($rootScope.currentUser) {
            $rootScope.currentUser.$destroy();
          } 
        }
    };

So I destroy the $rootScope.currentUser there. I use the same getCurrentUser for profile page. So the Error did not show up this way. But when in other views, which I have another $firebaseArray, and also another Ref.on("child_added", function(snap) with the same $firebaseObject. When I view the profile page, then this page with at least 3 firebase connection, I got 3 permission_denied Errors when I logout (logout button is on user profile page).

My question is, how do I disconnect this firebase connection before I logout? Is there a way disconnect ALL the firebase connection - no matter AngularFire or regular Firebase? So I can logout without worry about which firebase connection I have no close yet? Also, since the Logout button is in Profile scope and the others connection is in a different scope, I have no idea how to close the connection which is not even in the profile scope...

You need to destroy all the firebase references on logout. Something like this.

In logout function.

function logout() {
       auth.$unauth();
       $rootScope.$broadcast('logout');
};

In controller

vm.profile = authService.profile(user.uid); // FirebaseObject Reference
vm.parties = partyService.getPartiesByUser(user.uid); // FirebaseArray Reference

$rootScope.$on('logout', function () {
  vm.parties.$destroy();
  vm.profile.$destroy();
});
