带API平台的继承实体Symfony

Question

当我有一个从另一个实体继承的实体时，Platform API（https://api-platform.com/）存在问题。例如，从User实体继承的Worker实体。当我去到平台API文档的所有Worker属性出现在用户类

胜于解释的模式。这里是我的两个实体和问题

/** 
* User 
* 
* @ORM\Table(name="user") 
* @ORM\InheritanceType("SINGLE_TABLE") 
* @ORM\DiscriminatorColumn(name="discr", type="string") 
* @ORM\DiscriminatorMap({"user" = "User", "worker" = "Worker"}) 
* @ApiResource 
* 
*/ 
class User 
{ 
/** 
* @var int 
* 
* @ORM\Column(name="id", type="integer") 
* @ORM\Id 
* @ORM\GeneratedValue(strategy="AUTO") 
*/ 
protected $id; 

/** 
* @var string 
* 
* @ORM\Column(name="lastname", type="string", length=255) 
*/ 
protected $lastname; 

/** 
* @var string 
* 
* @ORM\Column(name="firstname", type="string", length=255) 
*/ 
protected $firstname; 


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

/** 
* Set lastname 
* 
* @param string $lastname 
* @return User 
*/ 
public function setLastname($lastname) 
{ 
    $this->lastname = $lastname; 

    return $this; 
} 

/** 
* Get lastname 
* 
* @return string 
*/ 
public function getLastname() 
{ 
    return $this->lastname; 
} 

/** 
* Set firstname 
* 
* @param string $firstname 
* @return User 
*/ 
public function setFirstname($firstname) 
{ 
    $this->firstname = $firstname; 

    return $this; 
} 

/** 
* Get firstname 
* 
* @return string 
*/ 
public function getFirstname() 
{ 
    return $this->firstname; 
} 
} 


/** 
* Worker 
* 
* @ApiResource 
*/ 
class Worker extends User 
{ 

/** 
* @var \DateTime 
* 
* @ORM\Column(name="birthday", type="datetime") 
* @Assert\NotNull() 
* @Assert\DateTime() 
*/ 
private $birthday; 

/** 
* @var string 
* 
* @ORM\Column(name="mobilePhone", type="string", length=255, nullable=true) 
*/ 
private $mobilePhone; 

/** 
* @return \DateTime 
*/ 
public function getBirthday(): \DateTime 
{ 
    return $this->birthday; 
} 

/** 
* @param \DateTime $birthday 
*/ 
public function setBirthday(\DateTime $birthday) 
{ 
    $this->birthday = $birthday; 
} 

/** 
* @return string 
*/ 
public function getMobilePhone(): string 
{ 
    return ($this->mobilePhone == null) ? '' : $this->mobilePhone; 
} 

/** 
* @param string $mobilePhone 
*/ 
public function setMobilePhone(string $mobilePhone) 
{ 
    $this->mobilePhone = $mobilePhone; 
} 

} 

文档的结果，这是问题。我们看到Worker类的属性出现在User类的模型中。而且，当我测试发送它返回一个包含工人实体的

你的序列化需要去深度将增加一个级别的属性的用户实体POST方法支持响应中序列化的工作人员属性。我不确定如何专门使其适用于您的实施。

随着JMS Serialization bundle，看起来像这样：

/** 
* Get the Birthday.. 
* 
* @MaxDepth(2) 
* @return \DateTime 
*/ 
public function getBirthday(): \DateTime 
{ 
    return $this->birthday; 
}
