Compare objects in angularjs - angularjs

Question

What I'm trying to achieve is that if a Post contains comments, it should display the comments. I tried the angular.equals, which either doesn't work or I am not familiar on how to use it right?
Here's the Controller for both Post and Comment.
var PostController = function ($scope, $location, Post, Comment) {
$scope.search = function () {
Post.query({
offset: $scope.offset,
limit: $scope.limit
},
function (data) {
$scope.more = data.length === 20;
$scope.posts = $scope.posts.concat(data);
});
};
$scope.searchComments = function () {
Comment.query({
},
function (data) {
$scope.comments = data;
});
};
$scope.showComment = function () {
angular.equals(Post, Comment);
}
}
And here's from the view:
<ul class="posts">
<li ng-repeat="post in posts">
<div class="post-info">
<h1>{{post.title}}</h1>
<div class="right-section">
<div class="edit-post-button right">Edit</div>
<span class="reputation right">{{post.reputation}}</span>
</div>
</div>
<br />
<div class="post-box">
<p>
{{post.content}}
</p>
</div>
<br />
<ul>
<li ng-repeat="comment in comments" ng-show="showComment()">
{{comment.content}}
</li>
</ul>
</li>
</ul>
Maybe this could be done in the back-end? I am not sure?

Answer 1

It seems like you want to filter the comments to a particaular post. As you have said in comments, the Comment resource has a pid that ties it to a particular post.
The best way to accomplish the filtering is with an angular filter.
In this way, you don't need to compare anything with equals, you can just filter the comments in the markup:
<ul>
<li ng-repeat="comment in comments | filter:{ pid: post.id }">
{{comment.content}}
</li>
</ul>
