Troubleshooting a potential JSON problem when linking Angular JS with Firebase

My current challenge is figuring out how to properly format firebase data to work seamlessly with Angular. I have a functional view that works with ng as a static display, and within the $scope it is defined like this:

$scope.standardItems = [{
    name: "The Name",
    sizeX: 2,
    sizeY: 1,
    row: 0,
    col: 0
}, {......etc

However, when attempting to supply data from firebase, it doesn't seem to work correctly, presumably because the output isn't formatted in the right way. The connection seems fine and data can be added, but firebase automatically inserts its own ID into the data. Here's an example of how the data looks when exported from the firebase console:

{
    "-KdJVcYUXMfeym3jPy04" : {
    "att" : "grid",
    "col" : 0,
    "id" : 1487476528646,
    "name" : "This is a test grid",
    "row" : 0,
    "sizeX" : 2,
    "sizeY" : 1
},

The additional parameters aren't crucial, but the structure is probably important. When I log the output of the firebase array using:

var todosRef = new Firebase('https://xxxxxxxxxx.firebaseio.com/');
$scope.todos = $firebaseArray(todosRef);
console.log($scope.todos);

I see the following in the Chrome debug console:

Array[0]
    0:Object
        $id: "-KjhbuvgtVvFUnbfbmj04"
        $priority:null
        att:"grid"
        col:0
        id:1487476528646
        name:"This is a test grid"
        row:0
        sizeX:2
        sizeY:1
    __proto__

Essentially, my question boils down to how can I ensure that Angular receives exactly what is being passed in the static example above from the controller? How can I accurately replicate what is being passed to Angular from the array - considering the discrepancies between the export from firebase console and the Chrome log console. It's challenging especially because all parent nodes have unique non-sequential IDs like -KdJVcYUXMfeym3jPy04, making it unclear how to extract or utilize them. Do I need a wildcard in the path? If so, what would it look like? The code functions perfectly with a static local array, so the issue lies in reading JSON from firebase.

Answer №1

Great news! The code provided here is error-free and Angular JS can successfully retrieve data from Firebase without any modifications. Both the Chrome console and the Firebase console will display the expected outputs, even with the addition of the "-adgadhfe445ggh45" index. In my own experience, a syntax error caused the ng-repeat to be excluded from the controller due to its placement outside of the closing div tag.

Fortunately, we have confirmed that there is no need to alter the structure of Firebase data in order for it to be accessible.
