What could be causing my directive to not display my scope?

I am currently developing a directive that includes a custom controller, and I am testing the scope functionality. However, I am facing an issue where the ng-show directive is not functioning as expected when trying to test if the directive has a scope from my index page.

html

<div class="main">
<div ng-controller="rl">

<book-genres></book-genres>
<review-form ng-show="reviewFormCtrl.rating == 1"></review-form>
<input ng-click="reviewFormCtrl.rating = 3" type="button" value="Test" /> 

</div>

</div>

partial:

<div>
    Review Forms : {{ rating }}

</div>

controller:

myApp.controller('rl', function(){

});

myApp.directive('reviewForm',  function(){
    return {
        restrict: 'E',
        templateUrl: 'partials/review-form.html',
        replace: true,
        scope: true,
        controller: function($scope){
                $scope.rating = 1;
        },
        controllerAs: 'reviewFormCtrl'
    };
});

Answer №1

Since you are utilizing the controller as syntax (for example, controllerAs: 'reviewFormCtrl'), it's recommended to attach the rating to the controller rather than the scope.

Here is the modified code:

myApp.directive('reviewForm',  function(){
  return {
    restrict: 'E',
    templateUrl: 'partials/review-form.html',
    replace: true,
    scope: true,
    controller: function(){
      this.rating = 1;  //change here
    },
    controllerAs: 'reviewFormCtrl'
  };
});

Answer №2

Following @Dustin Hodges' advice, here is a more organized approach:

Directive:

angular
 .module('myApp')
 .directive('reviewForm',  function(){

  var directive = {
      restrict    : 'E',
      templateUrl : 'partials/review-form.html',
      replace     : true,
      scope       : true,
      controller  : 'ReviewFormController'
      controllerAs: 'reviewformCtrl'
  };

 return directive;

});

Controller:

angular
  .module('myApp')
  .controller('ReviewFormController', ReviewFormController);

  ReviewFormController.$inject = [];//your dependencies

  function ReviewFormController(){

    var vm = this;

    vm.rating = 1;

  }

Template:

<div class="main">
 <book-genres></book-genres>
  <review-form ng-show="reviewformCtrl.rating == 1"></review-form>
</div>

I hope you find this cleaner format helpful.
