Question

我有一个Symfony表单集合，它实际上是嵌入一个表单，并且允许创建多个Specification对象，并且我收到一些不应出现的错误。

注意：

Symfony版本：2.3.30

实现：之前我已经使用过这个方法，并且根据Symfony文档完美地工作了（我甚至尝试使用这个方法从另一个项目中复制相关实体和表单，并且仍然会遇到相同的错误！）

代码：

实体：

<?php
/**
 * product
 * @package AppBundle\Entity
 * @author Pete Robinson
 **/
namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use AppBundle\Utils\Traits\Doctrine\Timestampable;
use Gedmo\Mapping\Annotation as Gedmo;

/**
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks
 * @ORM\Table(name="product")
 */
class Product
{
    ~snip snip snip - ID and other text fields~

    /**
     * specifications
     * @ORM\OneToMany(targetEntity="Specification", mappedBy="product")
     * @var object ArrayCollection
     **/
    private $specifications;

子实体：

<?php
/**
 * product
 * @package AppBundle\Entity
 **/
namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="specification")
 */
class Specification
{
    /**
     * product
     * @ORM\ManyToOne(targetEntity="Product", inversedBy="specifications")
     * @var object Product
     **/
    private $product;

表格：

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Validator\Constraints\NotBlank;
use Symfony\Component\Validator\Constraints\Regex;

class ProductType extends AbstractType
{
    /**
     * set default options
     * @return void
     **/
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'csrf_protection' => false,
            'data_class' => 'AppBundle\Entity\Product'
        ));
    }

    /**
     * build form
     * @param FormBuilderInterface $buidler
     * @param array $options
     * @return void
     **/
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder

            ->add('specifications', 'collection', array(
                'type' => new SpecificationType(),
                'allow_add' => true,
                'allow_delete' => true,
                'error_bubbling' => false,
                'cascade_validation' => true
            ))
        ;

错误：

 The options "allow_add", "allow_delete", "type" do not exist. Known options
 are: "action", "attr", "auto_initialize", "block_name", "by_reference", 
"cascade_validation", "compound", "constraints", "csrf_field_name",
"csrf_message", "csrf_protection", "csrf_provider", "data", "data_class",
"disabled", "empty_data", "error_bubbling", "error_mapping",
"extra_fields_message", "inherit_data", "intention", "invalid_message",
"invalid_message_parameters", "label", "label_attr", "mapped", "max_length",
"method", "pattern", "post_max_size_message", "property_path", "read_only",
"required", "translation_domain", "trim", "validation_groups", "virtual"

据我所知，我已经正确地遵循了关于嵌入式表格的Symfony文档，就像我一直一样 - 然而我遇到了这个问题。有没有人见过这个？

编辑：下面的SpecificationType - 与ProductType

具有相同名称空间的同一目录

    <?php
/**
 * specification form
 **/
namespace AdminBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Validator\Constraints\NotBlank;
use Symfony\Component\Validator\Constraints\Regex;

class SpecificationType extends AbstractType
{
    /**
     * set default options
     * @return void
     **/
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'csrf_protection' => false,
            'data_class' => 'AppBundle\Entity\Specification'
        ));
    }

    /**
     * build form
     * @param FormBuilderInterface $buidler
     * @param array $options
     * @return void
     **/
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('value', 'text', array(
                'label' => 'Value *',
                'label_attr' => array(
                    'class' => 'col-sm-2 control-label'
                ),
                'attr' => array(
                    'class' => 'form-control'
                ),
                'constraints' => array(
                    new NotBlank(array(
                        'message' => 'Specification value is required'
                    ))
                )
            ))
            ->add('remove', 'button', array(
                'attr' => array(
                    'class' => 'btn btn-danger right padded remove_item'
                )
            ))
        ;
    }

Answer 1

解决。我有一个名为Collection的教义实体，Product表格用于从中选择一个项目（在这个项目中，Collection本质上是一个Category）。出于某种原因，这在我希望使用symfony表单集合的表单对象中进一步搞乱。它都是命名空间，所以不应该有类冲突，但似乎Symfony不喜欢名为Collection的实体。

我将实体重命名为ProductCollection，并修复了尝试将嵌入表单用作集合的问题。

感谢您的建议。
