Php JMS组序列化和PagerFantaBundle

我正在使用Symfony和FOSRESTBundle开发一个RESTFull API。我使用带有组的JMS序列化程序根据上下文显示不同的字段

为了列出我的资源，我需要实现PagerFantaBundle。除了PagerFanta不考虑序列化组之外，所有这些都可以正常工作

下面是我的代码：

分页功能：

 protected function paginate(QueryBuilder $qb, $limit = 20, $offset = 0) {
    if($limit == 0 || $offset < 0) {
        throw new \LogicException("$limit & $offset must be greater than 0");
    }

    $pager = new Pagerfanta(new DoctrineORMAdapter($qb));
    $currentPage = ceil($offset + 1 / $limit);
    $pager->setCurrentPage($currentPage);
    $pager->setMaxPerPage((int) $limit);

    return $pager;
}

public function listApartments(Location $location, $order = 'asc', $limit = 20, $offset = 0) {
    $qb = $this->createQueryBuilder('a')
        ->select('a')
        ->orderBy('a.title', $order);

    return $this->paginate($qb, $limit, $offset);
}

控制器：

/**
 * @Rest\Get(
 *     path = "/apartments",
 *     name = "apartments_get_all"
 * )
 * @Rest\QueryParam(
 *     name="order",
 *     requirements="asc|desc",
 *     nullable=true,
 *     description="Sort order (asc or desc)"
 * )
 * @Rest\QueryParam(
 *     name="limit",
 *     requirements="\d+",
 *     default="20",
 *     description="Max number of apartments per page"
 * )
 * @Rest\QueryParam(
 *     name="offset",
 *     requirements="\d+",
 *     default="0",
 *     description="Pagination offset"
 * )
 * @Rest\View(statusCode=200, serializerGroups={"listApartment"})
 */
public function getApartmentsAction(ParamFetcherInterface $paramFetcher)
{
    $pager = $this->getDoctrine()->getRepository("HGBCoreBundle:Apartment")->listApartments(
        new Location(),
        $paramFetcher->get('order'),
        $paramFetcher->get('limit'),
        $paramFetcher->get('offset')
    );

    return new Apartments($pager);
}

公寓代表：

class Apartments
{
/**
 * @Type("array<HGB\CoreBundle\Entity\Apartment>")
 */
public $data;

public $meta;

public function __construct(Pagerfanta $data)
{
    $this->data = $data->getCurrentPageResults();

    $this->addMeta('limit', $data->getMaxPerPage());
    $this->addMeta('current_items', count($data->getCurrentPageResults()));
    $this->addMeta('total_items', $data->getNbResults());
    $this->addMeta('offset', $data->getCurrentPageOffsetStart());
}

public function addMeta($name, $value)
{
    if (isset($this->meta[$name])) {
        throw new \LogicException(sprintf('This meta already exists. You are trying to override this meta, use the setMeta method instead for the %s meta.', $name));
    }

    $this->setMeta($name, $value);
}

public function setMeta($name, $value)
{
    $this->meta[$name] = $value;
}
}

那么，如何在PagerFanta中使用组序列化，或者在组序列化中使用什么分页系统

谢谢，我找到了解决办法。只需按如下方式配置公寓表示的序列化组：

<?php


namespace HGB\CoreBundle\Representation;


use JMS\Serializer\Annotation as Serializer;
use Pagerfanta\Pagerfanta;

/**
 * Class Apartments
 * @package HGB\CoreBundle\Representation
 * @Serializer\ExclusionPolicy("all")
 */
class Apartments
{
/**
 * @Serializer\Type("array<HGB\CoreBundle\Entity\Apartment>")
 * @Serializer\Groups("listApartment")
 * @Serializer\Expose()
 */
public $data;

/**
 * @Serializer\Groups("listApartment")
 * @Serializer\Expose()
 */
public $meta;

public function __construct(Pagerfanta $data)
{
    $this->data = $data;

    $this->addMeta('limit', $data->getMaxPerPage());
    $this->addMeta('current_items', count($data->getCurrentPageResults()));
    $this->addMeta('total_items', $data->getNbResults());
    $this->addMeta('offset', $data->getCurrentPageOffsetStart());
}

public function addMeta($name, $value)
{
    if (isset($this->meta[$name])) {
        throw new \LogicException(sprintf('This meta already exists. You are trying to override this meta, use the setMeta method instead for the %s meta.', $name));
    }

    $this->setMeta($name, $value);
}

public function setMeta($name, $value)
{
    $this->meta[$name] = $value;
}
}

<?php


namespace HGB\CoreBundle\Representation;


use JMS\Serializer\Annotation as Serializer;
use Pagerfanta\Pagerfanta;

/**
 * Class Apartments
 * @package HGB\CoreBundle\Representation
 * @Serializer\ExclusionPolicy("all")
 */
class Apartments
{
/**
 * @Serializer\Type("array<HGB\CoreBundle\Entity\Apartment>")
 * @Serializer\Groups("listApartment")
 * @Serializer\Expose()
 */
public $data;

/**
 * @Serializer\Groups("listApartment")
 * @Serializer\Expose()
 */
public $meta;

public function __construct(Pagerfanta $data)
{
    $this->data = $data;

    $this->addMeta('limit', $data->getMaxPerPage());
    $this->addMeta('current_items', count($data->getCurrentPageResults()));
    $this->addMeta('total_items', $data->getNbResults());
    $this->addMeta('offset', $data->getCurrentPageOffsetStart());
}

public function addMeta($name, $value)
{
    if (isset($this->meta[$name])) {
        throw new \LogicException(sprintf('This meta already exists. You are trying to override this meta, use the setMeta method instead for the %s meta.', $name));
    }

    $this->setMeta($name, $value);
}

public function setMeta($name, $value)
{
    $this->meta[$name] = $value;
}
}
