Sonata Admin Bundle多对多的关系不保存国外ID

这是我的问题。我有两个具有多对多关系的实体，并希望在字段中插入多个信息。我使用管理奏鸣曲管理，这里是我的代码：Sonata Admin Bundle多对多的关系不保存国外ID

通知类：

<?php 

namespace App\BlogBundle\Entity;

     return $this; 
    } 

    /**

    public function removeNotification(\App\BlogBundle\Entity\Notification $notification)

    public function getNotification() 
    { 
     return $this->notification; 
    } 
}

最后我NotificationAdmin：

<?php 

namespace App\BlogBundle\Admin; 

use Sonata\AdminBundle\Admin\Admin; 
use Sonata\AdminBundle\Show\ShowMapper; 
use Sonata\AdminBundle\Form\FormMapper; 
use Sonata\AdminBundle\Datagrid\ListMapper; 
use Sonata\AdminBundle\Datagrid\DatagridMapper; 

class NotificationAdmin extends Admin { 

    // Fields to be shown on create/edit forms 
    protected function configureFormFields(FormMapper $formMapper) { 
     $formMapper 
       ->add('message', 'text') 
       ->add('etudiant', 'sonata_type_model', array(
        'required' => false, 
        'multiple' => true 
       )) 
     ; 
    } 

    // Fields to be shown on filter forms 
    protected function configureDatagridFilters(DatagridMapper $datagridMapper) { 
     $datagridMapper 
       ->add('message') 
       ->add('etudiant') 
     ; 
    } 

    // Fields to be shown on lists 
    protected function configureListFields(ListMapper $listMapper) { 
     $listMapper 
       ->addIdentifier('message') 
       ->add('etudiant') 
     ; 
    } 

    // Fields to be shown on show action 
    protected function configureShowFields(ShowMapper $showMapper) { 
     $showMapper 
       ->add('id') 
       ->add('nom') 

     ; 
    } 

    public function prePersist($notification){ 
     $this->preUpdate($notification); 
    } 
    public function preUpdate($notification){ 
     $notification->setEtudiant($notification); 
    } 

    public function getBatchActions() { 
     // retrieve the default batch actions (currently only delete) 
     $actions = parent::getBatchActions(); 

     if (
       $this->hasRoute('edit') && $this->isGranted('EDIT') && 
       $this->hasRoute('delete') && $this->isGranted('DELETE') 
     ) { 
      $actions['merge'] = array(
       'label' => 'action_merge', 
       'translation_domain' => 'SonataAdminBundle', 
       'ask_confirmation' => true 
      ); 
     } 

     return $actions; 
    } 

}

没有什么在我的表“etudiant_notification”。三江源，

请做如下修改（粗线）到您的代码：

Notification.php


/** 
* Add etudiant 
* 
* @param \App\BlogBundle\Entity\Etudiant $etudiant 
* @return Notification 
*/ 
public function addEtudiant(\App\BlogBundle\Entity\Etudiant $etudiant) 
{ 
    $etudiant->addNotification($this); 
    $this->etudiant[] = $etudiant; 

    return $this; 
}

Etudiant.php


/** 
* Add notification 
* 
* @param \App\BlogBundle\Entity\Notification $notification 
* @return Etudiant 
*/ 
public function addNotification(\App\BlogBundle\Entity\Notification $notification) 
{ 
    $notification->addEtudiant($this); 
    $this->notification[] = $notification; 

    return $this; 
}

和检查怎么了。没有保证，但你可以试试看。 Bonne的机会！

这给了我一个PHP错误“使用CONTROL-C退出服务器。内置服务器意外终止使用-v选项再次运行此命令以获取更多详细信息” –

此代码中有stackoverflow。例如，如果您调用'addNotification'，则在此方法内调用'addEtudiant'，这会导致调用'addNotification'。使用'if（$ notification-> getEtudiant（）== $ this）'像检查来打破堆栈溢出。 – svobol13

@ svobol13谢谢朋友！是的，代码中确实存在缺陷。改变只应该添加到反面，而不是目标面。应该添加'Notification.php'中的粗体行，但应删除'Etudiant.php'中的粗体行。 – cezar
