Doctrine : Pagination with left Joins

Question

I would like to paginate a complex request with at least 2 left joins, but the pagination bundle I\'m using (KnpPaginationBundle) can\'t tell Doctrine how to count the resul

Answer 1

For anyone looking for an answer about this, there is a good solution at: https://github.com/KnpLabs/KnpPaginatorBundle/blob/master/Resources/doc/manual_counting.md

$paginator = new Paginator;

// determine the count of the entire result set
$count = $entityManager
    ->createQuery('SELECT COUNT(c) FROM Entity\CompositeKey c')
    ->getSingleScalarResult();

// create a query to be used with the paginator, and specify a hint
$query = $entityManager
     ->createQuery('SELECT c FROM Entity\CompositeKey c')
     ->setHint(
        'knp_paginator.count', 
        $count
    );

// paginate, and set "disctinct" option to false
$pagination = $paginator->paginate(
    $query, 
    1, 
    10, 
    array(
        'distinct' => false,
    )
);

Basically, what you are doing, is you are creating your own 'count' query and instruct knp paginator to use this.
