Question

如何在Symfony 3.2中制作MongoId数组？Doctrine ODM正确序列化/反序列化？

文档

namespace Acme\StoreBundle\Document;
use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;

/**
 * @MongoDB\Document(collection="Voter")
 */

class Voter
{

/**
 * @MongoDB\Id
 */
protected $id;


/**
 * @MongoDB\Collection
 */

protected $inlist;


/**
 * Get id
 *
 * @return id $id
 */
public function getId()
{
    return $this->id;
}

public function setId($id)
{
    $this->id = $id;
    return $this;
}


/**
 * Set inlist
 *
 * @param collection $inlist
 * @return $this
 */
public function setInlist($inlist)
{
    $this->inlist = $inlist;
    return $this;
}

/**
 * Get inlist
 *
 * @return collection $inlist
 */
public function getInlist()
{
    return $this->inlist;
}

}

控制器：

/**
 * @Route("/voter/{id}")
 * @Method({"GET"})
 */

public function getAction($id)
{
    $product = $this->get('doctrine_mongodb')
        ->getRepository('AcmeStoreBundle:Voter')
        ->find($id);

    if (!$product) {
        throw $this->createNotFoundException('No product found for id ' . $id);
    }

    $serializer = $this->get('serializer');

    $data = $serializer->serialize(
        $product,
        'json'
    );

    $response = new JsonResponse();
    $response->setContent($data);
    return $response;
}

序列化Json：

{
"id": "593e99a8de6c84f5ecec3094",
"inlist": [
    {
        "timestamp": 1417718686,
        "pID": 3335,
        "inc": 9127278,
        "$id": "5480ab9e282e26070d8b456e"
    },
    {
        "timestamp": 1417718686,
        "pID": 3335,
        "inc": 9127273,
        "$id": "5480ab9e282e26070d8b4569"
    },
    {
        "timestamp": 1417718686,
        "pID": 3335,
        "inc": 9127272,
        "$id": "5480ab9e282e26070d8b4568"
    },
    {
        "timestamp": 1417718686,
        "pID": 3335,
        "inc": 9127275,
        "$id": "5480ab9e282e26070d8b456b"
    },
    {
        "timestamp": 1417718686,
        "pID": 3335,
        "inc": 9127274,
        "$id": "5480ab9e282e26070d8b456a"
    },
    {
        "timestamp": 1411754988,
        "pID": 2674,
        "inc": 9127271,
        "$id": "5425abec8f3723720a8b4567"
    }
]
}

我希望将它序列化为（字符串）id的数组，然后将其反序列化为MongoId的数组：

{
"id": "593e99a8de6c84f5ecec3094", 
"inlist": ['5425abec8f3723720a8b4567', '5480ab9e282e26070d8b456b' ...]
}

Answer 1

由于你在评论中提到了“正确的方法”，我将如何做到这一点：

class VoterAPIRepresentation
{
    public $id;

    public $inlist = [];

    public function __construct(Voter $voter)
    {
        $this->id = (string) $voter->id;
        foreach ($voter->inlist as $i) {
            $this->inlist[] = (string) $i['$id'];
        }
    }
}

上面的类负责API中的数据表示，因为实体本身不应该关注它。然后在控制器中：

public function getAction($id)
{
    $product = $this->get('doctrine_mongodb')
        ->getRepository('AcmeStoreBundle:Voter')
        ->find($id);

    if (!$product) {
        throw $this->createNotFoundException('No product found for id ' . $id);
    }

    $serializer = $this->get('serializer');

    $data = $serializer->serialize(
        new VoterAPIRepresentation($product),
        'json'
    );

    $response = new JsonResponse();
    $response->setContent($data);
    return $response;
}

这种方法的专业是，如果你改变实体，你不需要关心他们返回的任何端点和数据，因为这两个生命没有连接。另一方面，编写这样的类非常无聊，但它为复杂的对象和表示带来了回报。

Answer 2

setter / getter方式对我来说即使使用序列化器/解串器

也是如此

/**
 * Set actions
 *
 * @param collection $actions
 * @return $this
 */
public function setActions($actions)
{
    $re = [];
    foreach ($actions as $action) {
        $action['cid'] = new \MongoId($action['cid']);
        $re[] = $action;
    }

    $this->actions = $re;
    return $this;
}

/**
 * Get actions
 *
 * @return collection $actions
 */
public function getActions()
{
    $re = [];
    foreach ($this->actions as $action) {
        $action['cid'] = (string)$action['cid'];
        $re[] = $action;
    }

    return $re;
}
