[json] howto

[brikou]

mandango is great (I really mean it ;)) as it only query what is needed but I want to return a json representation of my collection

<?php
    // ...

    $labels = $app['mandango']
        ->getRepository('Model\Label')
        ->createQuery()
        ->all()
    ;

    return new Response(
        json_encode($labels),
        200,
        array('Content-Type' => 'application/json')
    );

$labels only contains ids of my labels, how should i do to hydrate this with all the data... do you have a clue? I havn't found anything in the doc

thx

<?php
    //...

    $labels = $app['mandango']
        ->getRepository('Model\Label')
        ->createQuery()
        ->all()
    ;

    array_walk($labels, function(\Model\Label &$label) {
        $label = $label->toArray();
    });

Is this code correct ?
