Answer 1

You can use the Criteria API to filter the collection:

<?php

use Doctrine\Common\Collections\Criteria;

class Article
{

    /**
     * @ORM\OneToMany(targetEntity="Comment", mappedBy="article")
     */
    protected $comments;

    public function getComments($showPending = false)
    {
        $criteria = Criteria::create();
        if ($showPending !== true) {
            $criteria->where(Criteria::expr()->eq('approved', true));
        }
        return $this->comments->matching($criteria);
    }

}

This is especially nice, because Doctrine is smart enough to only go to the database if the collection hasn't already been loaded.
