doctrine 2 and zend paginator

Question

i want to use doctrine with zend_paginator

here some example query :

$allArticleObj = $this->_em->getRepository(\'Articles\'); $qb

Answer 1

I was very surprised how hard it was to find an adapter example that doesn't cause performance issues with large collections for Doctrine 2 and ZF1.

My soultion does use the the Doctrine\ORM\Tools\Pagination\Paginator from Doctrine 2.2 just like @Kurt's answer; however the difference that this will return the doctrine paginator (Which is it's self an \Iterator) from getItems without the entire query results being hydrated.

use Doctrine\ORM\Tools\Pagination\Paginator as DoctrinePaginator;
use Doctrine\ORM\Query;

class DoctrinePaginatorAdapter implements \Zend_Paginator_Adapter_Interface
{
    protected $query;

    public function __construct(Query $query)
    {
        $this->query = $query;
    }

    public function count()
    {
        return $this->createDoctrinePaginator($this->query)->count();
    }

    public function getItems($offset, $itemCountPerPage)
    {
        $this->query->setFirstResult($offset)
                    ->setMaxResults($itemCountPerPage);

        return $this->createDoctrinePaginator($this->query);
    }

    protected function createDoctrinePaginator(Query $query, $isFetchJoinQuery = true)
    {
        return new DoctrinePaginator($query, $isFetchJoinQuery);
    }

}
