The target-entity "some entity" cannot be found
提问by noobie-php
i am using ZF2 with doctrine i am getting this error.
我正在使用带有学说的 ZF2 我收到此错误。
The target-entity Entity\User cannot be found in 'Subject\Entity\Subject#user'.
在“Subject\Entity\Subject#user”中找不到目标实体 Entity\User。
Here is the snippet to my code.
这是我的代码片段。
<?php
namespace Subject\Entity;
use Doctrine\ORM\Mapping as ORM;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\Factory as InputFactory;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;
/**
* @ORM\Entity
* @ORM\Table(name="subject")
* @property string $subjectname
* @property int $user_id
* @property int $id
*/
class Subject implements InputFilterAwareInterface {
protected $inputFilter;
/**
* @ORM\Id
* @ORM\Column(type="integer");
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string")
*/
protected $subjectname;
/**
* @ORM\ManyToOne(targetEntity="Entity\User", 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 Entity\User or null!');
}
}}
and then my "User" entity
然后是我的“用户”实体
namespace Subject\Entity;
use Doctrine\ORM\Mapping as ORM;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\Factory as InputFactory;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;
/*
* @ORM\Entity
* @ORM\Table(name="users")
* @property string $username
* @property string $password
* @property int $id
*/
class User implements InputFilterAwareInterface {
protected $_username;
protected $_password;
/**
* @ORM\OneToMany(targetEntity="Entity\Subject", mappedBy="user")
* @var Collection
*/
private $subjects;
/** @ORM\Id() @ORM\Column(type="integer") @ORM\GeneratedValue(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);
}
}
}

Your entity declaration is incorrect:
您的实体声明不正确：
* @ORM\ManyToOne(targetEntity="Entity\User", inversedBy="subjects")
This should be either this:
这应该是这样的：
* @ORM\ManyToOne(targetEntity="Subject\Entity\User", inversedBy="subjects")
Or, since the two classes share the same namespace, you can also use this:
或者，由于两个类共享相同的命名空间，您也可以使用：
* @ORM\ManyToOne(targetEntity="User", inversedBy="subjects")
The targetEntityhas 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).
的targetEntity必须是完全合格的类名（FQCN），除非指的是在相同的命名空间的一类，在这种情况下，可以使用短名称（按照上面的最后一个例子）。
