Is there a bug hiding in the Angular code for the Codecademy Calendar App waiting to be found?

Currently, I am working on the Codecademy task - CalendarApp utilizing AngularJS which involves services and routing. Unfortunately, it seems to have some issues as the data is not displaying correctly and the expression: {{ day.date | date }} appears as is without any processing.

Is there anyone who can identify where the mistake might be? I have reviewed examples from others but haven't been able to pinpoint the error.

Here are the snippets of code that might help in identifying the issue:

<html>
  <head>
    <link href="https://s3.amazonaws.com/codecademy-content/projects/bootstrap.min.css" rel="stylesheet" />
    <link href="css/main.css" rel="stylesheet" />
    <script src="js/vendor/angular.min.js"></script>
    <script src="https://code.angularjs.org/1.2.28/angular-route.min.js"></script>
  </head>
  <body ng-app="CalendarApp">
    <div class="header">
      <div class="container">
        <img src= "img/logo.svg" width="51" height="54">
      </div>
    </div>

    <div class="main">
       <div ng-view></div>

      <div class="container">


      </div>
    </div>

    <!-- Modules -->
    <script src="js/app.js"></script>

    <!-- Controllers -->
    <script src="js/controllers/DayController.js"></script>
    <script src="js/controllers/EventController.js"></script>

    <!-- Services -->
    <script src="js/services/events.js"></script>

  </body>
</html>

app.js:

var app = angular.module('CalendarApp', ['ngRoute']);
app.config(function ($routeProvider) {
 $routeProvider
 .when("/", {
    controller: 'DayController',
   templateUrl: 'views/day.html'
 })
 .when("/:id", {
        controller: 'EventController',
   templateUrl: 'views/event.html'
 })
 .otherwise({
 redirectTo: "/"
 });
});

events.js

  app.factory('events', ['$http', function($http) {
  return
  $http.get('https://s3.amazonaws.com/codecademy-content/courses/ltp4/events-api/events.json')
  .success(function(data) {
    return data;
  })
  .error(function(err) {
    return err;
  });
}]);

DayController.js

app.controller('DayController', ['$scope', 'events', function($scope, events) {
     events.success(function(data) {
      $scope.day = data;
     });
    }]);

EventController.js

   app.controller('EventController', ['$scope', 'events', '$routeParams', function($scope, events, $routeParams) {
  events.success(function(data) {
    $scope.event = data.events[$routeParams.id];
  });
}]);

day.html:

<h2 class="date"> {{ day.date | date }} </h2>
<div class="event" ng-repeat="event in day.events">
  <a href="#/{{$index}}">
    <h3 class="name">{{ event.name }} </h3>
    <p><span class="from">{{ event.from }}  </span> - <span class="to">{{ event.to }}  </span></p>
  </a>
</div>

event.html:

<div class="event-detail">
  <h2 class="event-name">{{ event.name }}</h2>
  <p class="time"><span class="from">{{ event.from }}  </span> - <span class="to">{{ event.to }}  </span></p>
  <p class="where">{{ event.where }}  </p>
</div>

Answer №1

An issue has arisen in your Angular application where it is displaying {{}} indicating that something may be broken within the code structure. Upon inspection, it appears the problem lies within the implementation of your factory and controller.

The error stems from returning a promise within the factory, while also utilizing the $http with both the .success and .error callbacks. This method creates an issue as attempting to return data from these callbacks interrupts the promise chain flow. A better approach would be to return the promise from the service, allowing the controller to attach necessary callbacks to handle the response.

Factory

app.factory('events', ['$http', function($http) {
   return $http.get('https://s3.amazonaws.com/codecademy-content/courses/ltp4/events-api/events.json');
}]);

By making this adjustment to your code structure, the encountered problem should be resolved.
