主义坚持和冲洗在Symfony中导致重复记录

Question

当我呼吁持续&刷新PersonalDevelopmentRequest实体时，它会导致数据库中存在重复记录。

我使用PHP 7.0.7，MySQL 5.6.28和Symfony 2.8.7。

UPDATE：当我在控制器的末尾删除重定向时，Doctrine只保留一次记录。可以重定向与教义有关吗？

守则控制器：

$request = new PersonalDevelopmentRequest(); 
$request 
    ->setTrainingGroup($training->getTrainingGroup()) 
    ->setTraining($training) 
    ->setEmployee($this->getUser()) 
    ->setName($training->getName()); 

$em = $this->getDoctrine()->getManager(); 

$em->persist($request); 
$em->flush(); 

$this->addFlash('success', 'Mám to.'); 

return $this->redirectToRoute('personal_development'); 

实体：

/** 
* PersonalDevelopmentRequest. 
* 
* @ORM\Table(name="personal_development_request") 
* @ORM\Entity(repositoryClass="AppBundle\Repository\PersonalDevelopmentRequestRepository") 
* @Gedmo\SoftDeleteable() 
*/ 
class PersonalDevelopmentRequest implements WorkflowInterface

    private $type;

    private $cost; 

    /**

    */ 
    private $mustBeRenewedAfter; 

    const TRAINING_TYPE_NONE = null; 
    const TRAINING_TYPE_INT = 'int'; 
    const TRAINING_TYPE_EXT = 'ext'; 

    /**

    private $trainingType; 

    /**

    private $rangeInHours; 

    /**

    * @ORM\JoinTable(name="personal_development_request_logs", 
    * joinColumns={@ORM\JoinColumn(name="personal_development_request_id", referencedColumnName="id")}, 
    * inverseJoinColumns={@ORM\JoinColumn(name="log_id", referencedColumnName="id", unique=true)} 
    *) 
    */ 
    private $logs; 

    ... 

谁能告诉我什么，我做错了什么？

Answer 1

我是由于在app.php中复制了$kernel->handle($request);而引起。

Answer 2

与给定的代码，我只能猜测你的代码块，坚持到数据库不在一个条件块（不在一个条件），并与你的更新，你说如果你删除redirectToRoute它解决它。所以它可能是一个重定向的循环，你可能会去同一个控制器两次，并坚持它两次，我会建议把它放在如条件，如$form->isValid()条件，例如，以避免自由坚持记录
