我正在尝试在我的Symfony2项目中创建一个用户系统，其中我有两种类型的用户; 买家和卖家。 他们都是用户，因此让他们扩展基本用户类是有意义的。
// Acme/UserBundle/Entity/BaseUser
/**
* @ORM\MappedSuperclass
*/
abstract class BaseUser implements UserInterface, \Serializable {
/**
* @ORM\Column(type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string", length=255, unique=true)
*/
protected $username;
/**
* @ORM\Column(type="string", length=255)
*/
protected $salt;
/**
* @ORM\Column(type="string", length=255)
*/
protected $password;
/**
* @ORM\Column(type="string", length=255)
*/
protected $email;
/**
* @ORM\Column(type="string", length=255)
*/
protected $region;
/**
* @ORM\Column(type="string", length=255)
*/
protected $city;
/**
* @ORM\Column(name="is_validated", type="boolean")
*/
protected $isValidated;
public function __construct() {
$this->isValidated = false;
$this->salt = md5(uniqid(null, true));
}
/**
* @inheritDoc
* All users must return the role: ROLE_USER
*/
public function getRoles() {
return array('ROLE_USER');
}
/**
* @inheritDoc
*/
public function eraseCredentials() {
}
/**
* @see \Serializable::serialize()
* We only need to return the ID because you can use the ID to load the rest from the database.
*/
public function serialize() {
return serialize(array(
$this->id,
));
}
public function unserialize($serialized) {
list (
$this->id,
) = unserialize($serialized);
}
// Getters and Setters removed
}
接下来是一个买家扩展该类：
// Acme/UserBundle/Entity/Buyer
/**
* ORM\Entity
* ORM\Table(name="buyer")
*/
class Buyer extends BaseUser {
/**
* @ORM\Column(name="first_name", type="string", length=255)
*/
protected $firstName;
/**
* @ORM\Column(name="last_name", type="string", length=255)
*/
protected $lastName;
/**
* @ORM\Column(name="date_of_birth", type="string", length=255)
*/
protected $dateOfBirth;
/**
* @ORM\Column(type="string", length=255)
*/
protected $gender;
/**
* @ORM\Column(name="mobile_number", type="string", length=255)
*/
protected $mobileNumber;
/**
* @ORM\Column(name="receive_newsletter", type="boolean", length=255)
*/
protected $receiveNewsletter;
/**
* @inheritDoc
* Buyers have their own buyer role
*/
public function getRoles() {
return array_push(parent::getRoles(), 'ROLE_BUYER');
}
}
我正在尝试使用Doctrine工具在Buyer.php中自动生成getter/setter方法，但是出现了以下错误信息：
$ php app/console doctrine:generate:entities Acme/UserBundle/Entity/Buyer
Generating entity "Acme\UserBundle\Entity\Buyer"
[Doctrine\ORM\Mapping\MappingException]
Class "Acme\UserBundle\Entity\Buyer" sub class of "Acme\UserBundle\En
tity\BaseUser" is not a valid entity or mapped super class.
doctrine:generate:entities [--path="..."] [--no-backup] name
我还没有亲自尝试实现这些方法，创建模式并持久化买家对象。如果工具显示出问题，那么我认为我做错了什么。
