Question

我有一个表单ProductForm，在该表单中我调用了base fieldset ProductFieldset，在ProductFieldset中我调用了CategoryFieldset。实体之间的关系是OneToOne。

以下是实体：

namespace Trunk\Entity;

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

/**
 * Product
 *
 * @ORM\Table(name="product")
 * @ORM\Entity
 */
class Product
{
    /**
     * @var integer
     *
     * @ORM\Column(name="Id", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    protected $id;

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

   /**
     * @ORM\OneToOne(targetEntity="Trunk\Entity\Category", mappedBy="product")
     * @ORM\JoinColumn(name="categoryid", referencedColumnName="id")
     */
    protected $category;

    public function __construct() {
        $this->category  = new ArrayCollection();
    }

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * @return int
     */
    public function getCategoryid()
    {
        return $this->categoryid;
    }

    /**
     * @param int $categoryid
     */
    public function setCategoryid($categoryid)
    {
        $this->categoryid = $categoryid;
    } 

    public function addCategory(Category $category)
    {
        if (! $this->category->contains($category)) {
            $this->category->add($category);
        }
        return $this;
    } 
    public function removeCategory(Category $category)
    {
        if ($this->category->contains($category)) {
            $this->category->removeElement($category);
        }
        return $this;
    }

    public function getCategory()
    {
        return $this->category;
    }
}

这是分类实体：

namespace Trunk\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Category
 *
 * @ORM\Table(name="category")
 * @ORM\Entity
 */
class Category
{
    /**
     * @var integer
     *
     * @ORM\Column(name="Id", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    private $id;

    /**
     * @var integer
     *
     * @ORM\Column(name="ParentId", type="integer", nullable=false)
     */
    private $parentid = '0';

    /**
     * @var string
     *
     * @ORM\Column(name="Title", type="string", length=255, nullable=false)
     */
    private $title;

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set title
     *
     * @param string $title
     *
     * @return Category
     */
    public function setTitle($title)
    {
        $this->title = $title;

        return $this;
    }

    /**
     * Get title
     *
     * @return string
     */
    public function getTitle()
    {
        return $this->title;
    }
}

提交表格后的结果是：

object(Trunk\Entity\Product)[480]
  protected 'id' => null
  protected 'categoryid' => null
  protected 'category' => 
    object(Doctrine\Common\Collections\ArrayCollection)[482]
      private 'elements' => 
        array (size=0)
          empty

我使用了Doctrine保湿剂，但是没有结果。

你能给我一些想法，为什么总是空的？提前谢谢！

更多代码

$form = $this->form;
$form->setAttribute('action', $this->url . '/admin/holiday/add/bg');
$form->prepare();
echo $this->form()->openTag($form);
$holiday = $form->get('product');
echo $this->formElement($holiday->get('category')->get('categoryid'));
echo $this->form()->closeTag();

这是控制器中的添加操作：

public function addAction()
{
    $oRequest = $this->getRequest();

    if ($oRequest->isPost()) {
        $aPost = $oRequest->getPost('product');

        $this->productForm->setData($oRequest->getPost());

        if ($this->productForm->isValid()) {

            try {
                $result = $this->productService->addProduct($this->productForm->getData());

                if ($result) {
                    return $this->redirect()->toRoute('trunk', array('controller' => 'product', 'action' => 'edit', 'id' => $result->getLang(), 'param' => $result->getId()));
                }
            } catch (\Exception $e) {
                // some DB error happened,, log it and let the user know
                exit;
            }
        }
    }

return new ViewModel(array(
    'form' => $this->productForm,
));

}

以下代码用于水合CategoryFieldset

中的对象

$this->setHydrator(new DoctrineHydrator($this->getObjectManager(), 'Trunk\Entity\Category'))
        ->setObject(new Category());

这就是我在ProductFieldset

中添加CategoryFieldset的方法

$this->add(array(
        'type' => 'Trunk\Form\CategoryFieldset',
        'name' => 'category'
    ));

编辑1：

ProductEntity中的ManyToOne关系

/**
 * @ORM\ManyToOne(targetEntity="Trunk\Entity\Category", inversedBy="products")
 * @ORM\JoinColumn(name="categoryid", referencedColumnName="id")
 */
protected $category;

CategoryEntity中的OneToMany关系

/**
 * @ORM\OneToMany(targetEntity="Trunk\Entity\Product", mappedBy="category")
 */
protected $products;

我收到以下错误

无法解析列的类型＆＃34; id＆＃34;类＆＃34; Trunk \ Entity \ Category＆＃34;

我检查了PersistHelper.php getTypeOfColumn函数中的代码，发现它正在寻找joinColumns。

问题已解决！

要修复我上次发布的关系错误，我必须在ProductEntity中使用此注释

/**
 * @ORM\ManyToOne(targetEntity="Trunk\Entity\Category", inversedBy="products")
 * @ORM\JoinColumn(name="CategoryId", referencedColumnName="Id")
 */
protected $category;

换句话说，我将引用列名称从“id”更改为Id（区分大小写）。

我希望这个问题和例子能够帮助其他同事。
