Doctrine Table 继承与 zf3 字段集

Question

我正在使用 Zend Framework 3 和 Doctrine 2 开发一个项目，用于 DcotrineModule 集成，以下是我遇到问题的实体建模：

为了使用我使用@InheritanceType 的学说进行建模，以下是实体的相关摘录：

Pessoa 实体：

/**
 * Abstração de Pessoa
 *
 * @author Rodrigo Teixeira Andreotti <ro.andriotti@gmail.com>
 * 
 * @Entity
 * @InheritanceType("JOINED")
 * @DiscriminatorColumn(name="tipo", type="string")
 * @DiscriminatorMap( { "pessoa" = "Pessoa", 
 *                      "pessoa_fisica" = "PessoaFisica",
 *                      "pessoa_juridica" = "PessoaJuridica" } )
 * @Table(name="pessoa")
 */
abstract class Pessoa implements JsonSerializable, PessoaInterface
{

    use JsonSerializeTrait;

    /**
     * @Id
     * @GeneratedValue(strategy="IDENTITY")
     * @Column(type="integer", length=32, unique=true, nullable=false, name="id_pessoa")
     * @var integer
     */
    protected $idPessoa;

    /**
     * Usuário
     * @OneToOne(targetEntity="User\Entity\User", inversedBy="pessoa", cascade={"persist"})
     * @JoinColumn(name="usuario", referencedColumnName="id")
     * 
     * @var User
     */
    protected $usuario;

    /**
     * @OneToOne(targetEntity="EnderecoPessoa", mappedBy="pessoa", cascade={"persist"})
     * @var EnderecoPessoa
     */
    protected $endereco;

    /**
     * Contatos da pessoa
     * @OneToMany(targetEntity="ContatoPessoa", mappedBy="pessoa", cascade={"persist"}, orphanRemoval=true)
     * @var ArrayCollection|array
     */
    protected $contatos;

    const PESSOA_FISICA = "pessoa_fisica", PESSOA_JURIDICA = "pessoa_juridica";

    public function __construct()
    {
        $this->contatos = new ArrayCollection();
    }
}

PessoaFisica 实体：

/**
 * Abstração da pessoa física
 *
 * @Entity
 * @Table(name="pessoa_fisica")
 * @author Rodrigo Teixeira Andreotti <ro.andriotti@gmail.com>
 */
class PessoaFisica extends Pessoa implements JsonSerializable {

    use JsonSerializeTrait;

    /**
     * Nome da pessoa física
     * @Column(type="string", length=14)
     * @var string
     */
    private $nome;

    /**
     * Número do CPF da pessoa (quando brasileiro)
     * @Column(type="string", length=14)
     * @var string
     */
    private $cpf;

    /**
     * Número do RG (quando brasileiro)
     * @Column(type="string", length=13)
     * @var string
     */
    private $rg;

    /**
     * Data de nascimento
     * @Column(type="date", name="data_nascimento")
     * @var DateTime
     */
    private $dataNascimento;
}

PessoaJuridica 实体：

/**
 * Abstração de Pessoa Jurídica
 * 
 * @Entity
 * @Table(name="pessoa_juridica")
 * @InheritanceType("JOINED")
 * @author Rodrigo Teixeira Andreotti <ro.andriotti@gmail.com>
 */
class PessoaJuridica extends Pessoa implements JsonSerializable {

    use JsonSerializeTrait;

    /**
     * @Id
     * @GeneratedValue(strategy="IDENTITY")
     * @Column(type="integer", length=32, unique=true, nullable=false, name="id_pessoa")
     * @var integer
     */
    protected $idPessoa;

    /**
     * Nome fantasia
     * @Column(type="string", length=32, name="nome_fantasia")
     * @var String
     */
    protected $nomeFantasia;

    /**
     * Número do CNPJ
     * @Column(type="string", length=14, unique=true, name="cnpj") 
     * @var string
     */
    protected $cnpj;

    /**
     * Razão social da empresa
     * @Column(type="string", length=32, name="razao_social")
     * @var string Razão social da empresa, quando necessário
     */
    protected $razaoSocial;
}

到目前为止一切正常，问题是当我需要为这些信息生成一个表格时，我目前正在研究 "Customer" 模块，基本上我为它所做的是：

使用客户端 ID + Pessoa 字段集创建表单
在 Pessoa 字段集中，我为共享信息（用户、地址、联系人等）创建了字段集
在 Pessoa Fieldset 中，它还包括另外两个 Fieldset，一个用于每个 Pessoa 的 child class（PessoaFisica 和 PessoaJuridica）——问题来了。

在下面的屏幕中你可以看到我的注册表：

此表单使用 javascript 根据所选类型显示或隐藏 PessoaJuridica 或 PessoaFisica 的字段集，但是由于它们在表单中是不同的字段集，因此当 zend 水化它们时，它们被水化为不同的 objects也一样，即继承不适用于Personobject，要根据类型选择。

基本上，在我看来，需要发生的是，zend 有一种方法可以不渲染引用 Person 的 child classes 的字段集class 作为单独的 objects，目前使用这些字段呈现表单，因此（例如）：

人 [fsPeople] [姓名]

人 [fsPessoaJuridica] [nameFantasica]

这导致 zend 无法生成正确的 class 保存在数据库中。

执行此表单的正确方法是什么？

好吧，@rkeet 的回复帮助我了解了问题出在哪里，这并不是真正的问题 =]

Due to the usage of inheritance, you've created separate Entities. However, the form you initially create in the back-end works with a single Entity. The front-end you've modified to handle 2. So your front-end does not match your back-end. As, due to the inheritance, you now have 2 separate Entities, you should create 2 separate forms, using different fieldsets (PessoaJuridica or PessoaFisica) as the base fieldsets.

我就把我走过的路留在这里，也许能帮到和我有同样疑惑的人。

首先，按照他评论中解释的逻辑，我为 PessoaEntity 创建了一个抽象字段集，其中包含两类人之间共享的信息，并将其扩展为两个子 classes PessoaFisicaFieldset 和 PessoaJuridicaFieldset，我在下面描述：

/**
 * Fieldset com dados para a pessoa
 *
 * @author Rodrigo Teixeira Andreotti <ro.andriotti@gmail.com>
 */
abstract class PessoaFieldset extends Fieldset implements InputFilterProviderInterface
{

    private $em;
    private $userFs;
    private $enderecoFs;
    private $contatoFs;

    public function __construct(ObjectManager $em,
            UserFieldset $userFs,
            PessoaEnderecoFieldset $enderecoFs,
            ContatoFieldset $contatoFs)
    {
        parent::__construct('pessoa');
        $this->em = $em;
        $this->userFs = $userFs;
        $this->enderecoFs = $enderecoFs;
        $this->contatoFs = $contatoFs;
        $this->init();
    }

    protected function getEm()
    {
        return $this->em;
    }

    public function init()
    {
        $this
                ->setHydrator(new DoctrineObject($this->getEm()));

        $this->add(array(
            'type' => 'Hidden',
            'name' => 'id_pessoa',
            'attributes' => array(
                'id' => 'txtId'
            )
        ));

        $this->add(array(
            'type' => 'hidden',
            'name' => 'tipo',
        ));


        $this->add($this->userFs);

        $this->add($this->enderecoFs);

        $elCollection = new Collection;
        $elCollection
                ->setName('contatos')
                ->setLabel('Informações de Contato')
                ->setCount(1)
                ->setShouldCreateTemplate(true)
                ->setAllowAdd(true)
                ->setAllowRemove(true)
                ->setTargetElement($this->contatoFs);


        $this->add($elCollection);

        $this->add(array(
            'type'  =>  'Button',
            'name'  =>  'btAddContato',
            'options' => array(
                'label' => '<i class="fa fa-fw fa-plus"></i> Adicionar',
                'label_options' => array(
                    'disable_html_escape' => true
                )
            ),
            'attributes' => array(
                'class' => 'btn btn-info',
                'id'    =>  'btAddContato'
            )
        ));
    }

    public function getInputFilterSpecification(): array
    {
        return array(
            'id_pessoa' =>  array(
                'required'  =>  false,
                'filters'   =>  array(
                    ['name'=>'Int']
                )
            ),
            'tipo'  =>  array(
                'required'  =>  true,
            )
        );
    }

}

这是我的 PessoaFisicaFieldset class。

这是我的 PessoaJuridicaFieldset

                )
            )
        );
    }

}

为了完成，我在将加载此表单的控制器上进行了实体类型处理，如下所示：（仅相关部分）

//...
if ($id) {
            $cliente = $this->repository->getById($id);
            $form->remove('pessoa');
            // loads form according to the type loaded from the database
            if (!$request->isXmlHttpRequest()) {
                if ($cliente->getPessoa() instanceof \Pessoa\Entity\PessoaFisica) {
                    $form->add($this->pessoaFisicaFieldset);
                } elseif ($cliente->getPessoa() instanceof \Pessoa\Entity\PessoaJuridica) {
                    $form->add($this->pessoaJuridicaFieldset);
                }
                var_dump($cliente->getPessoa());
            }
            $form->bind($cliente);
        }



        if ($request->isPost()) {
            $form->remove('pessoa');
            // loads form according to the type selected in the post
            if ($request->getPost('tipo') == \Pessoa\Entity\Pessoa::PESSOA_FISICA) {
