The controller is unable to recognize the injected service

var login_app = angular.module('login_app',[]);


login_app.factory('login_service', function($http) {
   return {
        loginUser: function() {
             //return the promise directly.
             return $http.get('/service/login')
                       .then(function(result) {
                            //resolve the promise as the data
                            return result.data;
                        });
        }
   }
});  

login_app.controller('login_controller',
                    ['$scope','login_service'
                     function($scope, login_service){

                      $scope.login_username = "";
                      $scope.login_password = "";
                      $scope.remember_login = false;
                      $scope.login_button_action = function(){
                                                     login_service.loginUser();
                                                 }

                    }]);

I have a login form integrated with this controller and everything seems to be functioning properly. Whenever I click on the login button, it triggers the login_button_action through ng-click directive.

I'm encountering an issue where my JavaScript console keeps showing this error message.

ReferenceError: login_service is not defined

Do you see any issues with how my controller is utilizing the service?

javascriptangularjs

Answer №1

Make sure to include the login_service in your definitions like this:

login_app.controller('login_controller', ['$scope','login_service',
    function($scope,login_service){
        // Implement your code that utilizes the service here.
}]);

Additionally, don't forget to link the service script file in your document.

If you're not concerned about minification or similar issues, then you can simply do:

login_app.controller('login_controller', function($scope, login_service){
      // Implement your code that utilizes the service here.
 }]);
