I have 4 entities as Product, ProductFeatures, Goods, GoodsFeaturesValue and relations between them. I add some Features for Product and then I whant create form with static fields Goods + some new Features from Product for this Goods. Values for each Goods saved in GoodsFeaturesValue.

如何以“匿名方式”建立这种形式?

附文

I use Collection for other Features and this work mini, but how i can setbell from ProductFeatures relation for each Value? 在使寺庙化时,我能够这样做,但这不好:

//GoodsFormType class
public function buildForm(FormBuilder $builder, array $options)
{
    $builder
            ->add( name )
            //other property...
            ->add( values ,  collection , array(
                 required  => true,
                 type  => new GoodsFeaturesValueFormType(),
                 allow_add  => false,
                 allow_delete  => false,
                 by_reference  => false,
            ))
    ;
}

//GoodsFeaturesValueFormType
    public function buildForm(FormBuilder $builder, array $options)
{
    $builder
            ->add( value ,  text )
    ;
}
  //controller
  public function saveAction($id)
{
    $em = $this->getDoctrine()->getEntityManager();
    $product = $em->getRepository( ShopCoreBundle:Product )->find($id);

    if (!$product)
        throw $this->createNotFoundException(sprintf( Product with id %s not found , $id));

    $features = $em->getRepository( ShopCoreBundle:ProductFeatures )->findByProduct($id);
    $goods = new Goods();
    $goods->setProduct($product);

    foreach ($features as $feature) {
        $entity = new GoodsFeaturesValue();
        $entity->setFeatures($feature);
        $entity->setGoods($goods);
        $entity->setProduct($product);
        $goods->addGoodsFeaturesValue($entity);
    }

    $request = $this->getRequest();

    $form = $this->createForm(new GoodsFormType(), $goods);
    $form->bindRequest($request);

    if ($form->isValid()) {
        $em->persist($goods);
        $em->flush();
        return $this->redirect($this->generateUrl( core_product_index ));
    }



    return array(
         form  => $form->createView(),
         goods  => $goods,
         product  => $product,
         features  => $features,
    );
}
