Question

I’m using Doctrine 2 Paginator and i’m experiencing a bug (maybe) with Twig. Consider a simple Paginator initialization:

    $current = 1;
    $limit   = 5;
    $offset  = ($current - 1) * $limit;

    $qb->setFirstResult($offset)->setMaxResults($this->limit);

    // No fetch joins
    $items = new \Doctrine\ORM\Tools\Pagination\Paginator($qb->getQuery, false);

    // Total count
    var_dump($items->count()); // Prints 8

    // Number of items displayed
    var_dump(count($items)); // Prints 5

    // Items
    foreach($items as $item) :
        var_dump($items->getId()); // Prints 1, 2, 3, 4, 5
    endif;

Counts are just fine to me. But after assigning it to Twig with array('items' => $items):

{% for item in items %}
    {{ loop.index }}/{{ loop.length }}
{% endfo %}

Output is wrong, in particular loop.length refers to the entire collection (not the current set of items). So, for example, you can’t use loop.last:

1/8
2/8
3/8
4/8
5/8

Self answer. This code from Doctrine documentation has led me astray:

$paginator = new Paginator($query, $fetchJoinCollection = true);

$c = count($paginator);
foreach ($paginator as $post) {
    echo $post->getHeadline() . "\n";
}

Wrong. You have to assign the iterator to Twig, not the paginator instance itself:

return array('items' => $paginator->getIterator());

EDIT: sorry i found that count($paginator) == $paginator->count(), so current items count is $paginator->getIterator()->count().
