目标实体“某个实体"找不到

问题描述

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);
}

}

推荐答案

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).
