添加Form Symfony2

Question

我使用symfony2：我有3个实体Piece，Brand和model。添加一件作品时，我必须注明品牌和型号。当我做CRUD时，一切正常，它向我展示了所有的品牌和型号。除了我想要的时候我选择这个品牌，它只向我展示了与这个品牌相关的模特。

class Piece {
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

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

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

    /**
     * @var string
     *
     * @ORM\Column(name="ref1", type="string", length=255)
     */
    private $ref1;

    /**
     * @var string
     *
     * @ORM\Column(name="ref2", type="string", length=255)
     */
    private $ref2;

    /**
     * @var string

    private $ref3;

    /**

    private $modele;

    private $localisation;


    /**

    function setLocalisation($localisation) {
        $this->localisation = $localisation;

    function getMar() {
        $m=new Marque();
        return $m->getNom();
    }

PieceType.php

   public function buildForm(FormBuilderInterface $builder, array $options){
        $builder->add('refference')
                ->add('description')
                ->add('localisation')
                ->add('ref1')

                ->add('marque')
                ->add('modele');
    }

如果你不想使用AJAX，你可以使用CraueFormFlowBundle创建一个包含不同步骤的FormType，并在symfony中制定一些规则。
