与Doctrine 2保存OneToMany和ManyToMany关系的错误 [英] error saving OneToMany and ManyToMany relationship with Doctrine 2

问题描述

我的Doctrine2有问题。当尝试保存关系ManyToMany或OneToOnePHP离开异常错误！我留下错误，以便您可以帮助我。

致命错误：未捕获的异常'InvalidArgumentException'与消息'一个新的实体通过关系实体找到通过\用户＃privilege'未配置为级联持久化实体的操作：实体\权限@ 0000000012feb12000000000616126d4。明确地或坚持新的实体设置级联持续关系的操作。如果您无法通过实现实体Entities \ Privilege＃__toString（）来找出哪些原因导致问题，以获得线索。 C：\ Program Files \ EasyPHP-5.3.4.0 \ www \ mframework_2 \ phpinc \ Doctrine \ ORM \ UnitOfWork.php第576行

我用于保持关系的代码是：

 
 
 $ user = new \Entities\User ）; 
 $ user-> setActive（true）; 
 $ user-> setUsername（'xxx'）; 
 $ user-> setPassword（'xxx'）; 
 
 $ email = new \Entities\Email（）; 
 $ email-> setEmail（xxx'）; 
 $ email-> setType（'xxx'）; 
 
 $ user-> addEmail（$ email）; 
 
 $ this-> em-> persist（$ user）; 
 $ this-> em-> flush（）; 
 
 

在Entitie用户中我有：

 
  / ** @OneToOne（targetEntity =Privilege）* / 
 protected $ privilege; 
  
 

我有同样的问题whit ManyToMany关系！

非常感谢！

解决方案

将cascade = {persist}添加到您的特权字段中：

  / ** @OneToOne（cascade = {persist}，targetEntity =Privilege）* / 
 protected $ privilege; 
  

I have a problem with "Doctrine2". When attempting to save a relationship "ManyToMany" or "OneToOne" PHP leave exception error! I leave the error so that you can help me.

Fatal error: Uncaught exception 'InvalidArgumentException' with message 'A new entity WAS found Through the Relationship' Entities \ User # privilege 'That Was not configured to cascade persist Operations for entity: Entities \ Privilege @ 0000000012feb12000000000616126d4. Explicitly or persist the new entity set up cascading persist Operations on the relationship. If you can not find out Which Causes the problem by implementing entity 'Entities \ Privilege # __toString ()' to get a clue. "in C: \ Program Files \ EasyPHP-5.3.4.0 \ www \ mframework_2 \ phpinc \ Doctrine \ ORM \ UnitOfWork.php on line 576

The code I use to keep the relationship is:

    $user = new \Entities\User();
            $user->setActive(true);
            $user->setUsername('xxx');
            $user->setPassword('xxx');

    $email = new \Entities\Email();
            $email->setEmail(xxx');
            $email->setType('xxx');

    $user->addEmail($email);

    $this->em->persist($user);
            $this->em->flush();

In the Entitie User I have this:

/** @OneToOne(targetEntity="Privilege") */
    protected $privilege;

I have the same problem whit ManyToMany relationships!

Thankyou very much!

解决方案

Add cascade={"persist"} to your privilege field:

/** @OneToOne(cascade={"persist"}, targetEntity="Privilege") */
protected $privilege;
