Symfony2教义2许多形式不保存实体 [英] Symfony2 Doctrine2 Many To Many Form not Saving Entities

问题描述

我有很多关系的麻烦。我有用户和资产。我希望能够将用户分配给资产页面上的资产。

下面的代码在创建/编辑资产时显示用户列表，但是更改对于用户，复选框不保存，而剩余的数据将被保留。

如果我通过mysql客户端添加一个条目到users_assets，这些更改显示在资产清单。

用户

  class User extends BaseUser 
 {
 / ** 
 * @ ORM\ManyToMany（targetEntity =Asset，inversedBy =users）
 * / 
 private $资产; 
} 
  

资产

  class Asset 
 {
 / ** 
 * @ ORM\ManyToMany（targetEntity =User，mappedBy =资产）
 * / 
 private $ users; 
} 
  

资产类型

  public function buildForm（FormBuilderInterface $ builder，array $ options）
 {
 $ form = $ builder 
  - > add （'users'，null，array（
'expanded'=> true，
'multiple'=> true 
））
  - > getForm（）; 
 
 return $ form; 
} 
  

解决方案

由于某种原因，切换教义映射以使其正常工作：

 资产：
 / ** 
 * @ORM \ManyToMany（targetEntity =Adaptive\UserBundle\Entity\User，inversedBy =assets）
 * @ ORM\JoinTable（name =user_assets）
 * / 
私人$用户; 
 
用户：
 / ** 
 * @ ORM\ManyToMany（targetEntity =Splash\SiteBundle\Entity\Asset，mappedBy =users）
 * / 
私人资产; 
  

现在，当我保存资产时，会保存与之关联的用户。我不需要将builder-> add定义为实体或集合。我只是传递它，它使用映射信息来填写实体信息：

  AssetType：
  - > ; add（'users'，null，array（'expanded'=>true，multiple=>true））
  

不完全确定为什么我需要在资产与用户上拥有inversedBy和JoinTable信息，但现在似乎正在工作！

感谢您的建议!!!

I am having some trouble with a many to many relationship. I have Users and Assets. I would like to be able to assign users to an asset on the asset page.

The code below displays a list of users when creating/editing an asset, however changes made to the user checkboxes do not save, while the rest of the data is persisted.

If I add an entry to users_assets through the mysql client, these changes are shown in the asset list.

User

class User extends BaseUser
{
    /**
     * @ORM\ManyToMany(targetEntity="Asset", inversedBy="users")
     */
    private $assets;
}

Asset

class Asset
{
    /**
     * @ORM\ManyToMany(targetEntity="User", mappedBy="assets")
     */
    private $users;
}

AssetType

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $form = $builder
        ->add('users', null, array(
            'expanded' => true,
            'multiple' => true
        ))
        ->getForm();

    return $form;
}

解决方案

For some reason I had to switch the doctrine mappings to get this to work:

Asset:
 /**
 * @ORM\ManyToMany(targetEntity="Adaptive\UserBundle\Entity\User", inversedBy="assets")
 * @ORM\JoinTable(name="user_assets")
 */
private $users;

User:
 /**
 * @ORM\ManyToMany(targetEntity="Splash\SiteBundle\Entity\Asset", mappedBy="users")
 */
private $assets;

Now when I save the asset it saves the users associated. I did not need to define builder->add as an entity or collection. I simply pass it null and it uses the mapping info to fill in the entity info:

AssetType:
->add('users', null, array('expanded' => "true", "multiple" => "true"))

Not exactly sure why I needed to have the inversedBy and JoinTable info on the Asset vs The User but it seems to be working now!

Thanks For The Suggestions!!!
