Utiliser ng-if comme commutateur dans ng-repeat?

Je travaille sur Angular app. J'ai essayé d'utiliser ng-if et de passer à l'intérieur ng-repeat mais je n'ai pas réussi. J'ai des données comme:

   **[{"_id":"52fb84fac6b93c152d8b4569",
       "post_id":"52fb84fac6b93c152d8b4567",
       "user_id":"52df9ab5c6b93c8e2a8b4567",
       "type":"hoot",},  
      {"_id":"52fb798cc6b93c74298b4568",
       "post_id":"52fb798cc6b93c74298b4567",
       "user_id":"52df9ab5c6b93c8e2a8b4567",
       "type":"story",},        
      {"_id":"52fb7977c6b93c5c2c8b456b",
       "post_id":"52fb7977c6b93c5c2c8b456a",
       "user_id":"52df9ab5c6b93c8e2a8b4567",
       "type":"article",},**

$ scope.comments = données mentionnées ci-dessus
et mon HTML comme:

   <div ng-repeat = "data in comments">
      <div ng-if="hoot == data.type">
          //differnt template with hoot data
       </div>
      <div ng-if="story == data.type">
          //differnt template with story data
       </div>
       <div ng-if="article == data.type">
          //differnt template with article data
       </div> 
   </div>

Comment puis-je réaliser cette chose en angulaire?

Essayez d'encadrer strings (hoot, story, article) avec des guillemets ':

<div ng-repeat = "data in comments">
    <div ng-if="data.type == 'hoot' ">
        //different template with hoot data
    </div>
    <div ng-if="data.type == 'story' ">
        //different template with story data
    </div>
    <div ng-if="data.type == 'article' ">
        //different template with article data
    </div> 
</div>

Celui-ci est remarquable aussi

<div ng-repeat="post in posts" ng-if="post.type=='article'">
  <h1>{{post.title}}</h1>
</div>

Je vais suggérer de déplacer tous les modèles dans des fichiers séparés, et de ne pas faire de spagetti dans la répétition

jetez un oeil ici:

html:

<div ng-repeat = "data in comments">
    <div ng-include src="buildUrl(data.type)"></div>
 </div>

js:

var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {

  $scope.comments = [
    {"_id":"52fb84fac6b93c152d8b4569",
       "post_id":"52fb84fac6b93c152d8b4567",
       "user_id":"52df9ab5c6b93c8e2a8b4567",
       "type":"hoot"},  
    {"_id":"52fb798cc6b93c74298b4568",
       "post_id":"52fb798cc6b93c74298b4567",
       "user_id":"52df9ab5c6b93c8e2a8b4567",
       "type":"story"},        
    {"_id":"52fb7977c6b93c5c2c8b456b",
       "post_id":"52fb7977c6b93c5c2c8b456a",
       "user_id":"52df9ab5c6b93c8e2a8b4567",
       "type":"article"}
  ];

  $scope.buildUrl = function(type) {
    return type + '.html';
  }
});
