Symfony2.1实体字段类型多重扩展不保存

标签: php doctrine-orm symfony-2.1 symfony-forms

在Symfony 2.1中使用实体字段类型时,我遇到了双向关系(一对多)的问题。在创建子(Product)并选择父(Category)时,所有内容都是hunky dory,它会按预期创建并保留。创建父(Category)并选择由Symfony2的表单系统生成的多个子(Product)复选框时会出现问题。 这不会持续

我将把我的示例类放在下面,但是克隆我的示例项目repo可能更容易 - https://github.com/domudall/multiple-expanded-entity-choice-issue

分类

class Category
{
    protected $id;
    protected $name;

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

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

    public function addProduct($product)
    {
        if (!$this->products->contains($product)) {
            $this->products->add($product);
            $product->setCategory($this);
        }

        return $this;
    }

    public function setProducts($products)
    {
        foreach ($products as $product) {
            $this->addProduct($product);
        }

        return $this;
    }

    public function removeProducts()
    {
        if ($this->products->contains($product)) {
            $this->products->remove($product);
        }

        return $this;
    }
}

产品

class Product
{
    protected $id;
    protected $name;

    /**
     * @ORM\ManyToOne(targetEntity="Category", inversedBy="products")
     */
    protected $category;

    public function setCategory(Category $category)
    {
        $this->category = $category;
        $category->addProduct($this);

        return $this;
    }

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

DefaultController

class DefaultController extends Controller
{
    public function categoryCreateAction(Request $request)
    {
        $category = new Category();

        $form = $this
            ->createFormBuilder($category)
            ->add('name', 'text', array())
            ->add('products', 'entity', array(
                'class' => 'AcmeShopBundle:Product',
                'property' => 'name',
                'required' => false,
                'expanded' => true,
                'multiple' => true,
            ))
            ->getForm();

        if ($request->getMethod() == 'POST') {
            $this->save($category, $form, $request);
        }
    }

    public function productCreateAction(Request $request)
    {
        $product = new Product();

        $form = $this
            ->createFormBuilder($product)
            ->add('name', 'text')
            ->add('category', 'entity', array(
                'class' => 'AcmeShopBundle:Category',
                'property' => 'name',
                'required' => false,
            ))
            ->getForm();

        if ($request->getMethod() == 'POST') {
            $this->save($product, $form, $request);
        }
    }

    protected function save($entity, $form, $request)
    {
        $form->bind($request);

        if ($form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $em->persist($entity);
            $em->flush();
        }
    }
}

任何指向我出错的地方都会非常感激。

注意

我不想使用Doctrine cascade选项,而是将单元测试实体中的逻辑与db分开。

如果您不想级联,则必须手动保留这些实体。

我使用了集合的map()方法(下方),但您可以通过集合的foreach方法使用array_maptoArray()

尝试以下控制器代码:

protected function saveCategory($category, $form, $request)
{
    $form->bind($request);

    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();           
        $entity->getProducts()->map(
            function($product) use ($em) {
                $em->persist($product);
            }
        );

        $em->persist($category);
        $em->flush();
    }
}
