一對一，單向關係

Question

我有這些實體： - 商店和包裝

我想建立一個StoreType表單，我添加包Id。

我做了的storetype Form類：（我期望從中得到一個選擇框，所有的包都列出）

我已經通過一對一的添加軟件包，但我的問題是當我在商店窗體中添加包時，表單是創建的，但在我的數據庫存儲表中，列包是空的。我不知道爲什麼？

Store.php

/** 
* @ORM\Entity 
*/ 
class Store 
    { 
     /** 
     * @ORM\Id 
     * @ORM\Column(type="integer") 
     * @ORM\GeneratedValue(strategy="AUTO") 
     */ 
     protected $id; 

     /** 
     * @ORM\Column(type="string", length="255") 
     */ 
     protected $title; 

     /** 
     * @ORM\Column(type="string", length="255") 
     */ 
     protected $domain; 

     /** 
     * @ORM\OneToOne(targetEntity="Package",cascade={"persist", "remove"}) 
     * @ORM\JoinColumn(name="package_id", referencedColumnName="id") 
     */ 
     protected $package; 
    } 

Package.php

/** 
* @ORM\Entity 
*/ 
class Package 
    { 
     /** 
      * @ORM\Id 
      * @ORM\Column(type="integer") 
      * @ORM\GeneratedValue(strategy="AUTO") 
      */ 
     protected $id; 

     /** 
      * @ORM\Column(type="string", length=255) 
      */ 
     protected $title; 

     /** 
      * @ORM\Column(type="text", length="4000") 
      */ 
     protected $description; 

     /** 
      * @ORM\Column(type="boolean") 
      */ 
     protected $active; 


     public function __toString() 
      { 
      return $this->getTitle(); 
      } 
    } 

StoreType.php

class StoreType extends AbstractType 
    { 
     public function buildForm(FormBuilder $builder, array $options) 
     { 
      $builder 
       ->add('title') 
       ->add('domain') 
       ->add('package','entity',array(
        'class' => 'WebmuchProductBundle:Package', 
      ));

     public function getName() 
     { 
      return 'webmuch_productbundle_storetype'; 
     }

我想你忘記了這樣做在你的createAction：

$request = $this->getRequest(); 
$form->setData($request->getPost());
