Attempting to incorporate my Resolve into the controller so that it can then be injected into the HTML

Here is the content of my index.js file:

'use strict';

angular.module('wildenglish', ['ngAnimate', 'ngTouch', 'restangular', 'ngRoute',     'ui.bootstrap'])
  .config(function ($routeProvider, RestangularProvider) {

RestangularProvider.setBaseUrl('https://www.googleapis.com/calendar/v3/calendars/googleCalendarID');

$routeProvider
  .when('/', {
    templateUrl: 'app/main/main.html',
    controller: 'MainCtrl',
    resolve: {
            calendarEvents: function(Restangular){
                return Restangular.one('eventsAUTHKEY').get();
            }
        }
  })
  .otherwise({
    redirectTo: '/'
  });


 })

Now, in my main controller.js:

'use strict';

angular.module('wildenglish')

   .controller('MainCtrl', function(Restangular, calendarEvents) {
      var self = this,
      events = calendarEvents,
      items = events.items;

});

After implementing this code, I encountered the following error when trying to use it in the HTML:

Error: [$injector:unpr] Unknown provider: calendarEventsProvider <- calendarEvents <- MainCtrl

I am now looking for solutions on how to make the data from the Promise accessible to the HTML via the controller. Do I need a service or factory? And where should I implement it?

Thank you for your assistance.

Answer №1

Transfer the events retrieved from the resolved promise to your controller's scope. Adjust the dependencies you are injecting into your controller by excluding Restangular since the promise is being resolved in your route, but make sure to include $scope:

angular.module('wildenglish').controller('MainCtrl', function($scope, calendarEvents) {

    // Assuming that this code logs your events to the console
    // If not, there may be an issue with your Restangular request
    console.log(calendarEvents);

    // Assign calendarEvents to $scope
    $scope.events = calendarEvents;

});

You can now utilize the events in your HTML template (assuming each event has a 'name' property):

<ul>
    <li ng-repeat="event in events">{{event.name}}</li>
</ul>

Apologies for missing the previously provided correct answer.

I encountered a similar issue before, which can be found in this link:

AngularJS, resolve and unknown provider

In essence, if you are utilizing routeProvider to assign your controller in the script file, avoid using ng-controller in your template.
