Symfony 4 + Sonata Admin - 在继承属性中找不到属性的元数据

Question

当我尝试向管理员添加过滤器时出现错误已有一段时间了。有两个实体：Client 和 Order.

在 OrderAdmin 文件中，以下过滤器有效：

$datagridMapper
    ->add('id')
    ->add('client.email')
    ->add('client.id')
;

但是如果我添加这一行 ->add('client.name') 它会触发这个错误：

No metadata found for property `App\Entity\Order::$client.name. Please make sure your Doctrine mapping is properly configured.

Client 实体由另外两个实体继承。它们都包含属性名称。而 id 和 email 都存在于父实体中。我猜这就是出现错误的原因：

* @ORM\InheritanceType("JOINED")
* @ORM\DiscriminatorColumn(name="type", type="string")
* @ORM\DiscriminatorMap({"user_1" = "one", "user_2" = "two"})

这在以前的版本上运行良好。知道如何解决这个问题吗？（将名字属性转移到父 class 对我来说并不是真正的解决方案）。

编辑：订单 class

<?php

namespace App\Entity;

/**
 * Order
 *
 * @ORM\Table(name="Order")
 * @ORM\Entity(repositoryClass="App\Repository\OrderRepository")
 */
class Order
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var float
     *
     * @ORM\Column(name="amount", type="float", nullable=true)
     */
    private $amount;

    /**
     * @var \DateTime
     *
     * @Gedmo\Timestampable(on="create")
     * @ORM\Column(name="date", type="datetime")
     */
    private $date;

    /**
     * @var string
     *
     * @ORM\Column(name="state", type="string", length=30, nullable=true)
     */
    private $state;

    /**
    * @ORM\ManyToOne(targetEntity="App\Entity\Client")
    */
    private $client;

    /**
    * @ORM\OneToMany(targetEntity="App\Entity\Article", mappedBy="order", cascade={"persist", "remove"}, orphanRemoval=true)
    */
    private $articles;

bundles.php

Answer 1

在这种情况下，这是由于 class 配置造成的。在 Sf DI 期间注入映射，但未找到此自定义用户 Class。

只需检查 News Bundle 使用的 classes。

sonata_news:
    class:
        post:       Application\Sonata\NewsBundle\Entity\Post
        comment:    Application\Sonata\NewsBundle\Entity\Comment
        media:      Application\Sonata\MediaBundle\Entity\Media
        user:       My\Custom\UserBundle\Entity\User

Answer 2

通过执行此处提到的过滤器回调来解决： https://symfony.com/doc/master/bundles/SonataAdminBundle/reference/action_list.html#callback-filter

我很想知道版本之间发生了什么变化，代码不再工作，但也许在其他时间！
