Utilizing AngularJS's ng-repeat directive to iterate over an array stored in a $

My controller successfully retrieves and pushes an object onto an array using Parse:

var mySite = angular.module('mySite', []);

mySite.controller('listConnectors', ['$scope',
    function ($scope) {
        //Parse.initialize here;
        $scope.array = [];
        var TestObject = Parse.Object.extend("TestObject");
        var query = new Parse.Query(TestObject);
        query.find({
            success: function (results) {
                alert("Successfully retrieved " + results.length + " rows.");
                // Do something with the returned Parse.Object values
                for (var i = 0; i < results.length; i++) {
                    var object = results[i];
                    alert(object.id + ' - ' + object.get('foo') + " " + object.get('num'));

                    /***** Pushing onto array here *******/
                    $scope.array.push(object);

                }

                console.log($scope.array[0].attributes.foo); //Grabbed what was needed

            },
            error: function (error) {
                alert("Error: " + error.code + " " + error.message);
            }
        });
}]);

I'm having trouble looping and listing the "foo" value of every object in the array, as shown by the console.log above. Nothing is being outputted. It seems like the ng-repeat might not be executing or entering:

<li ng-repeat="eachElement in array">
    <a > {{eachElement.attributes.foo}}</a>
</li>

If you have any suggestions, I would appreciate it. Thanks!

Answer №1

After some troubleshooting, I managed to resolve the issue with the help of Jonathan Lonowski's insightful comment and provided link.

To successfully add an object to an array, I had to utilize $apply like so:

$scope.$apply(function(){
  $scope.array.push(object);
});

Answer №2

The code in your alert statement and inside the ng-repeat directive are not consistent. The alert is referencing "x.id" while the DOM binding uses "x.attributes.id".

If the alert is displaying the desired output, you need to update the HTML like so:

<li ng-repeat="eachElement in array">
<a > {{eachElement.id}}</a>
</li>
