AngularJS is throwing a ReferenceError due to a reference to an undefined property

I'm really struggling with my AngularJS controller (and I think my controller is just as confused by my code). My issue is that I have groups and users, where the user can select a group. However, I'm having trouble accessing the SelectedClass in the user object. The console keeps telling me it's undefined, even though I've already defined it at the top of the controller like this: $scope.SelectedClass = {}; Here's an excerpt from my controller:

$scope.SelectedClass = {};
$http.get('/groups').then(function(result){
    console.log(result);
    $scope.groups = result.data;
    $scope.SelectedClass = $scope.groups[0];
    $scope.changed = function() {
        console.log($scope.SelectedClass);
    }
});

$http.get('/users').then(function(result){
    console.log(result);
    $scope.allusers = {};
    $scope.allusers = result.data;
    
    console.log($scope.SelectedClass.group_id);
});

Can anyone offer guidance on what might be going wrong here? Any help would be greatly appreciated!

Answer №1

Aha, I finally cracked it! Turns out, the issue was a ridiculously silly error on my part.

It turns out that there is no data in my test database for $scope.groups[0], which explains why it was showing as undefined.

Note to self: remember to thoroughly verify my database next time around.
