Easily add some logic to filter out specific entities from an ArrayCollection in Symfony2. In this simple example, I wrote an app that had Node, and Comment entities separately, as well as an explicitly defined NodeComment entity. In my Node entity, I want to serialize all of the associated comments. But rather than call ->getNodeComments() and then filter in AngularJS (or Twig, or whatever else for that matter), I just want to know that my object node.comments are the actual comments I care about.
The Entity property
|
1 2 3 4 5 |
/** * @Expose * @AccessType("getComments") */ protected $node_comments; |
The Accessor
|
1 2 3 4 5 6 7 8 9 10 11 |
/** * @return array */ public function getComments() { $comments = new \Doctrine\Common\Collections\ArrayCollection(); foreach($this->node_comments as $nodeComment) { $comments->add($nodeComment->getComment()); } return $comments; } |
Now, my serialized object.comments are the actual comments, instead of the ManyToMany Entity.

Why don’t you use array_map (or ArrayCollection::map())?
return $this->node_comments->map(function ($nodeComment) {
return $nodeComment->getComment();
});
