AngularJS $scope changes not reflecting in the view

Struggling with a persistent issue in my angularJS $scope. I've been working on updating an array within a controller function, and even though the values are changing based on console logs, the view isn't reflecting those changes. Here's what I have:

//array initialization

    $scope.fieldSuggestions = []

//modification function

  $scope.changeCurrentInput = function(fieldName, eye) {
    for(var field in $scope.test){
      console.log($scope.test[field].name)
      if($scope.test[field].name === fieldName){
        console.log($scope.test[field].values)
        console.log("before update")
        console.log($scope.fieldSuggestions)
        $scope.fieldSuggestions = $scope.test[field].values;
        console.log("after update")
        console.log($scope.fieldSuggestions)
      }
    }
  };

//view

 <div ng-repeat="choice in fieldSuggestions">       
    <button class="button button-positive">{{choice}}</button>
</div>

ADDITIONAL INFORMATION...

A potential clue to this problem is that I'm dealing with a parent view along with multiple child views. All of these routes share the same controller. Specifically, the property controller in routes.js remains constant across all routes. The button triggering the modification function is located in the child views, while the ng-repeat that fails to update is in the parent view.

Answer №1

When making changes to nested properties, Angular may not trigger digests. To solve this issue, you can add a link or controller function in your code:

$scope.$watchCollection('fieldSuggestions', function(newFieldSuggestions, oldFieldSuggestions) {
  $scope.fieldSuggestions= newFieldSuggestions;
}); 

It's important to note that this approach may not be the most efficient for large collections and complicated objects.

Answer №2

After some investigation, I realized that my issue stemmed from shadowing the parent fieldSuggestions variable by mistakenly declaring my child controllers as identical to the parent. The key was to avoid redeclaring the controller on the child routes, allowing it to inherit automatically from the parent.

Grateful for all the assistance provided by everyone.

Answer №3

It seems that due to the nesting change, the value cannot be updated at that moment. To get the latest updated value, you can utilize $scope.$apply(). For example: $scope.$apply($scope.fieldSuggestions = $scope.test[field].values);
