覆盖DoctrineExtensions Taggable的序列化程序元数据

Question

我可以覆盖标记对象序列化的方式吗？目前返回所有内容,我想排除id,created_at,updated_at和标记.我正在使用JMS Serializer软件包,Doctrine Extensions Taggable和FPN Tag Bundle.

这是我的设置,我想在实体的命名空间实际上是DoctrineExtensions可能是问题时将Tag Bundle的父设置为FPN.

大多数实体参数都在DoctrineExtensions\Taggable\Entity\Tag(id,name,created_at等)中.我正在覆盖扩展DoctrineExtensions的FPN包.DoctrineExtensions是一个库而不是一个包.

我怎样才能做到这一点？

# app/config/config.yml
# ...
jms_serializer:
    metadata:
        auto_detection: true
        directories:
            TagBundle:
                namespace_prefix: "FPN\\TagBundle"
                path: "@MYTagBundle/Resources/config/serializer/fpn"


# MY\TagBundle\Resources\config\serializer\fpn\Entity.Tag.yml
FPN\TagBundle\Entity\Tag:
    exclusion_policy: ALL
    properties:
        id:
            expose: false
        name:
            expose: true
        created_at:
            expose: false
        updated_at:
            expose: false
        tagging:
            expose: false


# src/MY/TagBundle/Entity/Tag.php
<?php
namespace MY\TagBundle\Entity;

use FPN\TagBundle\Entity\Tag as BaseTag;

class Tag extends BaseTag
{
}


# vendor/fpn/tag-bundle/FPN/TagBundle/Entity/Tag.php
<?php

namespace FPN\TagBundle\Entity;

use DoctrineExtensions\Taggable\Entity\Tag as BaseTag;

class Tag extends BaseTag
{
    ....
}



# src/MY/TagBundle/MYTagBundle.php
<?php

namespace MY\TagBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class MYTagBundle extends Bundle
{
    // Is this unnecessary due to config.yml?
    public function getParent()
    {
        return 'FPNTagBundle';
    }
}

JMSSerializer 要求您在与声明属性的命名空间相同的命名空间中定义序列化配置。

例如，假设您有一个具有和属性Application\Bundle\AcmeBundle\Entity\BaseModel的类，以及一个继承具有属性的类的类。在这种情况下，您将需要 2 个序列化文件：一个以序列化配置和属性命名；另一个以序列化配置命名。以及一个以属性配置命名的。$createdAt$updatedAtApplication\Bundle\AcmeBundle\Entity\ModelBaseModel$nameEntity.BaseModel.xml$createdAt$updatedAtEntity.Model.xml$name

您很好地覆盖了 FPNTagBundle 的配置，但是您可以使用当前配置配置序列化的唯一字段是该$slug字段（在FPN\TagBundle\Entity\Tag类中定义）。对于其他字段，您需要覆盖 的配置目录DoctrineExtensions\Taggable\Entity\Tag。

你的配置应该是这样的：

# app/config/config.yml
# ...
jms_serializer:
    metadata:
        auto_detection: true
        directories:
            TagBundle:
                namespace_prefix: "FPN\\TagBundle"
                path: "@MYTagBundle/Resources/config/serializer/fpn"
            DoctrineTaggable:
                namespace_prefix: "DoctrineExtensions\\Taggable"
                path: "@MYTagBundle/Resources/config/serializer/doctrine"


# MY\TagBundle\Resources\config\serializer\fpn\Entity.Tag.yml
FPN\TagBundle\Entity\Tag:
    exclusion_policy: ALL
    properties:
        id:
            expose: false
        name:
            expose: true
        created_at:
            expose: false
        updated_at:
            expose: false
        tagging:
            expose: false
# MY\TagBundle\Resources\config\serializer\fpn\Entity.Tag.yml
FPN\TagBundle\Entity\Tag:
    exclusion_policy: ALL
    properties:
        slug:
            expose: false # or true, as you wish :)
