Injecting service variable to Directives

Question

So I am having a bit of trouble. I have looked through all of the previous solutions from Injecting service to Directive, but I really have no idea what I'm doing wrong. I have an authServices shown below.

app.factory('authService', ['$http', function ($http) {

var authServiceFactory = {};

var _authentication = {
    isAuth: false,
    userName: ""
};
var _login = function (loginData) {
_authentication.isAuth = true;
_authentication.userName = loginData.userName;
}
appFactory.login = _login;
return appFactory;
}]);

I am injecting it via the method they had proposed.

    app.directive('headerNotification', ['authService', function (authService) {
    return {
        templateUrl: 'app/scripts/directives/header/header-notification/header-notification.html',
    restrict: 'E',
    replace: true,
    link: function (scope) {
        scope.authService = authService;
    }
    }
}]);

My html is as

    <li data-ng-hide="authentication.isAuth">

I really feel I am just doing this wrong. Any help would be greatly appreciated.

Answer 1

what is authentication.isAuth in your view.

I think you miss spelled your object.

<li data-ng-hide="authService.isAuth">

Your scope object is authService not authentication, right?

Update - Pass veraible to directive

I am assuming that you have your auth variable in your controller.

$scope.myAuthService = authservice;

Noe you can pass this variable to your directive as an attribute.

<header-notification my-auth="myAuthService"> </header-notification>

Here myAuthService is a scope variable.

Change your directive to accept this variable,

app.directive('headerNotification', function () {
    return {
                templateUrl: 'app/scripts/directives/header/header-notification/header-notification.html',
                restrict: 'E',
                scope : {
                            myAuth : '=' // here you specify that you need to convert your attribute variable 'my-auth' to your directive's scope variable 'myAuth'
                        },
                replace: true,
                link: function (scope, element, attr, controller) {
                      // here you will get your auth variable
                      scope.myAuth; // this contains your auth details
                }
            }
});
