我在使用 ZF2 时遇到了这个错误.
i am using ZF2 with doctrine i am getting this error.
在SubjectEntitySubject#user"中找不到目标实体 EntityUser.
The target-entity EntityUser cannot be found in 'SubjectEntitySubject#user'.
这是我的代码片段.
<?php
namespace SubjectEntity;
use DoctrineORMMapping as ORM;
use ZendInputFilterInputFilter;
use ZendInputFilterFactory as InputFactory;
use ZendInputFilterInputFilterAwareInterface;
use ZendInputFilterInputFilterInterface;
/**
* @ORMEntity
* @ORMTable(name="subject")
* @property string $subjectname
* @property int $user_id
* @property int $id
*/
class Subject implements InputFilterAwareInterface {
protected $inputFilter;
/**
* @ORMId
* @ORMColumn(type="integer");
* @ORMGeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORMColumn(type="string")
*/
protected $subjectname;
/**
* @ORMManyToOne(targetEntity="EntityUser", inversedBy="subjects")
* @var User|null
*/
private $user;
/** @return User|null */
public function getUser() {
return $this->user;
}
/** @param User $user */
public function setUser(User $user) {
if($user === null || $user instanceof User) {
$this->user = $user;
} else {
throw new InvalidArgumentException('$user must be instance of EntityUser or null!');
}
}}
然后是我的用户"实体
namespace SubjectEntity;
use DoctrineORMMapping as ORM;
use ZendInputFilterInputFilter;
use ZendInputFilterFactory as InputFactory;
use ZendInputFilterInputFilterAwareInterface;
use ZendInputFilterInputFilterInterface;
/*
* @ORMEntity
* @ORMTable(name="users")
* @property string $username
* @property string $password
* @property int $id
*/
class User implements InputFilterAwareInterface {
protected $_username;
protected $_password;
/**
* @ORMOneToMany(targetEntity="EntitySubject", mappedBy="user")
* @var Collection
*/
private $subjects;
/** @ORMId() @ORMColumn(type="integer") @ORMGeneratedValue(strategy="AUTO") @var int */
protected $_id;
public function __get($property) {
return $this->$property;
}
public function __set($property, $value) {
$this->$property = $value;
}
//Getters and setters
/** @return Collection */
public function getSubjects() {
return $this->comments;
}
/** @param Comment $comment */
public function addSubject(Subject $comment) {
$this->comments->add($comment);
$comment->setUser($this);
}
}
你的实体声明不正确:
* @ORMManyToOne(targetEntity="EntityUser", inversedBy="subjects")
这应该是这样的:
* @ORMManyToOne(targetEntity="SubjectEntityUser", inversedBy="subjects")
或者，由于两个类共享同一个命名空间，你也可以这样使用:
Or, since the two classes share the same namespace, you can also use this:
* @ORMManyToOne(targetEntity="User", inversedBy="subjects")
targetEntity 必须是完全限定的类名 (FQCN)，除非引用同一命名空间中的类，在这种情况下可以使用短名称(根据最后一个示例以上).
The targetEntity has to be the fully qualified class name (FQCN), except if referring to a class in the same namespace, in which case the short name may be used (as per the last example above).
