Angular fails to refresh the display

For a while now, I have been working with Angular without encountering many difficulties. I have a controller that triggers a function on an ng-change event. This particular controller is responsible for generating different reports based on select filters defined in the main PrincipalController.

While most controllers function as expected, I am currently facing some challenges with the AnalisisEvaluacionController. The initial view loads correctly, and I can display the name, but when I call the method from an ng-change event, the name does not update. Additionally, I have an ng-repeat over $scope.notas that is not functioning properly. This is where my primary issue lies. Despite trying to resolve it by using $scope.$apply() and $scope.$digest(), I keep encountering the following error:

angular.js:14800 Error: [$rootScope:inprog] $apply already in progress

I have included a code snippet at for reference.

The crux of the problem lies in having an ng-repeat over evaluacion.notas, which should be refreshed when the generarInforme function is called. This function calls a factory that retrieves JSON data assigned to $scope.evaluacion within the controller. However, I am unable to iterate through or display the required data.

Answer №1

It is not necessary to manually call $scope.$apply (or $digest) within the ng-change handler, as it is already encapsulated in a $scope.$apply block. However, if there are specific scenarios where you do need to trigger $scope.$apply (or $digest) after an asynchronous operation within the ng-change handler, you can prevent errors by following this approach: 

(scope.$$phase || scope.$root.$$phase) ? fn() : scope.$apply(fn);

Another option is to wrap your fn function inside a $timeout block.

$timeout(fn)

This method safely triggers $scope.$apply.

Answer №2

To address the issue at hand, I decided to establish a new function called init within the AnalisisEvaluacionController. This function would then proceed to execute the generarInforme method and update all necessary variables accordingly.
