ZF2 Doctrine2 - 保存隐藏标识字段关联实体

Question

我有以下情况：

“公司” 1..1“菜单” 1..1“MenuCategory”

对于添加的类别，我有一个单独的窗体与相关菜单的ID的隐藏字段。如果我想保存的范畴，我得到以下异常：

SQLSTATE [23000]：完整性约束违规：1048列 'menu_id' 不能为空

，如果我的var_dump $形式 - > getData（）在我的控制器中进行验证检查后，我得到以下响应，其中关联的菜单为空。我是否必须先加载菜单并将其分配给我想要保存的新类别？

object(Company\Entity\MenuCategory)#483 (4) { 
    ["id":protected]=>NULL 
    ["name":protected]=> string(4) "Test" 
    ["description":protected]=>NULL 
    ["menu":protected]=>NULL 
} 

这里是我的相关类（我缩短他们的相关部分）：

菜单

use Company\Entity\Company; 
use Doctrine\ORM\Mapping as ORM; 
use DateTime; 

/** 
* @ORM\Entity(repositoryClass="Company\Repository\Doctrine\MenuRepository") 
* @ORM\Table(name="menu") 
*/ 
class Menu { 

    /** 
    * @var integer 
    * 
    * @ORM\Id 
    * @ORM\Column(type="integer", name="id") 
    * @ORM\GeneratedValue 
    */ 
    protected $id; 

    /** 
    * @var string 
    * 
    * @ORM\Column(type="string", name="name", nullable=false) 
    */ 
    protected $name; 

    /** 
    * @var string 
    * 
    * @ORM\Column(type="string", name="description", nullable=false) 
    */ 
    protected $description; 

    /** 
    * @var \Company\Entity\MenuCategory[] 
    * 
    * @ORM\OneToMany(targetEntity="Company\Entity\MenuCategory", mappedBy="menu", cascade={"remove"}) 
    */ 
    protected $categories; 
} 

MenuCategory

use Doctrine\Common\Collections\ArrayCollection; 
use Doctrine\ORM\Mapping as ORM; 

/** 
* @ORM\Entity(repositoryClass="Company\Repository\Doctrine\MenuCategoryRepository") 
* @ORM\Table(name="menu_category") 
*/ 
class MenuCategory { 

    /** 
    * @var integer 
    * 
    * @ORM\Id 
    * @ORM\Column(type="integer", name="id") 
    * @ORM\GeneratedValue 
    */ 
    protected $id; 

    /** 
    * @var string 
    * 
    * @ORM\Column(type="string", name="name") 
    */ 
    protected $name; 

    /** 
    * @var string 
    * 
    * @ORM\Column(type="string", name="description", nullable=true) 
    */ 
    protected $description; 

    /** 
    * @var \Company\Entity\Menu 
    * 
    * @ORM\ManyToOne(targetEntity="Company\Entity\Menu", inversedBy="categories") 
    * @ORM\JoinColumn(nullable=false) 
    */ 
    protected $menu; 
} 

MenuCategoryForm

use Doctrine\Common\Persistence\ObjectManager; 
use DoctrineModule\Persistence\ObjectManagerAwareInterface; 
use Zend\Form\Form;  

class MenuCategoryForm extends Form implements ObjectManagerAwareInterface { 

    protected $objectManager; 

    public function init() { 
     $this->add(array(
      'type' => 'hidden', 
      'name' => 'menu_id', 
      'attributes' => array(
       'required' => 'required' 
      ) 
     )); 

     $this->add(array(
      'name' => 'name', 
      'options' => array(
       'label' => 'Name' 
      ), 
      'attributes' => array(
       'id' => 'menu-category-name', 
       'required' => 'required' 
      ) 
     )); 

     $this->add(array(
      'type' => 'textarea', 
      'name' => 'description', 
      'options' => array(
       'label' => 'Beschreibung' 
      ), 
      'attributes' => array(
       'id' => 'menu-category-description' 
      ) 
     )); 
    } 

    public function setObjectManager(ObjectManager $objectManager) { 
     $this->objectManager = $objectManager; 
     return $this; 
    } 

    public function getObjectManager() { 
     return $this->objectManager; 
    } 
} 

MenuCategoryFormFactory

use Company\Entity\MenuCategory; 
use Company\Form\MenuCategoryForm; 
use Zend\ServiceManager\ServiceLocatorInterface; 
use Zend\ServiceManager\FactoryInterface; 

class MenuCategoryFormFactory implements FactoryInterface { 

    public function createService(ServiceLocatorInterface $formElementManager) { 
     $serviceLocator = $formElementManager->getServiceLocator(); 
     $hydratorManager = $serviceLocator->get('HydratorManager'); 
     $inputFilterManager = $serviceLocator->get('InputFilterManager'); 

     $form = new MenuCategoryForm(); 
     $form->setInputFilter($inputFilterManager->get('Company\InputFilter\MenuCategory')); 
     $form->setHydrator($hydratorManager->get('Application\Hydrator\Doctrine')); 
     $form->bind(new MenuCategory()); 

     return $form; 
    } 

} 

控制器

use Company\Service\MenuServiceInterface; 
use Doctrine\ORM\Query; 
use Zend\Mvc\Controller\AbstractRestfulController; 
use Zend\View\Model\JsonModel; 

class MenuCategoryAdminRestController extends AbstractRestfulController { 
    protected $menuService; 

    protected $menuCategoryForm; 

    public function __construct(MenuServiceInterface $menuService) { 
     $this->menuService = $menuService; 
    } 

    public function create($data) { 
     $form = $this->getMenuCategoryForm(); 
     $form->setData($data); 

     if ($form->isValid()) { 
      $this->getMenuService()->saveMenuCategory($form->getData()); 
     } 

     return new JsonModel(); 
    } 
} 

Answer 1

你的表单字段MenuCategoryForm :: menu_id不映射到MenuCategory：菜单。将名称从menu_id更改为菜单。

至于水合作用，您可以将菜单ID分配给MenuCategoryForm：菜单字段，并且当保湿时，映射的实体将由教条的水化器加载。从doctrine hydrator doc中检查此section以进行解释。
