Tips for retrieving refreshed ($scope) data following a change in location using $window.location

In my AngularJS application, I have implemented an update form that allows users to post updates. After submitting the form, the JSON file is immediately updated as expected. To return to the main page upon pressing the save-update button, I utilize $window.location.href.

However, upon returning to the main page, the data displayed is not automatically refreshed. Although refreshing the page manually (by pressing F5) works, I am seeking a way to have the data updated automatically upon returning to the main page.

Based on the information I have researched regarding $window.location.href reloading the page, I had anticipated that this would also refresh the data when changing the location in my application. Unfortunately, this does not seem to be the case currently.

Is there a method to have the data on the main page updated without requiring manual page refresh?

Form Controller:

myDash.controller("dbNewUpdateCtrl", function($scope, $window, dbDataService){

    //Save + Cancel
    $scope.updateSave = function (item) {
        dbDataService.saveUpdate(item);
        $window.location.href = "#/dashboard";
    }

    $scope.updateCancel = function () {
        $window.location.href = "#/dashboard";
    }
});

Main Page Controller

myDash.controller("dbOverviewCtrl", function($scope, $routeParams, dbDataService){

    $scope.items = dbDataService.getData();

});

Answer №1

If you're utilizing the ngRoute Module, utilize the $location.path() Method to automatically update the $scope.

In cases where it is not being used, make sure to manually implement changes by invoking the $scope.$apply() Method on the scope prior to modifying the location.

Answer №2

It's crucial to utilize $location.path() over $window.location.href. Make sure to redirect your page after saving data in the service, specifically on the callback of the save function.

To verify the data retrieved after a page redirect, set breakpoints in the Main Page Controller. Confirm that the data is correctly obtained from the service and that it is assigned to $scope.items.

If the data is not updating, use $scope.apply() to save the information. If there are any errors related to $digest(), employ the following code snippet:

$timeout(function(){
   $scope.items = dbTestService.getData();
},0);

This script will refresh the value of $scope.items.

I trust this advice proves helpful. Warm regards

Answer №3

Avoid using window.location.href as it can disrupt the single page application flow. Data is likely stored in dbDataService - make sure to re-fetch it after sending data to the database.
