Symfony表單收集-錯誤

Question

我有一個Symfony表單集合，該集合本質上是嵌入表單，並且將允許創建多個Specification對象，並且出現了許多錯誤，這些錯誤不應該出現。

筆記：

Symfony版本：2.3.30

實施：我以前使用過這種方法，並且根據Symfony文檔，它已經完美地工作了（我什至嘗試使用該方法從另一個項目中復制relevent實體和表單，這種方法確實適用於該方法，並且仍然出現相同的錯誤！）

碼：

實體：

<?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;

子實體：

<?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
            ))
        ;

錯誤：

 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"

據我所知，我一直正確地遵循有關嵌入式表單的Symfony文檔，這與我一貫一樣-但是卻遇到了這個問題。 有人看過嗎？

編輯：下面的SpecificationType-在與ProductType相同名稱空間的同一目錄中

    <?php
/**

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(

                    'class' => 'btn btn-danger right padded remove_item'

    }

Answer 1

解決了。 我有一個名為Collection的學說實體，Product表單用於從中選擇一個項目（在此項目中，Collection本質上是一個Category）。 由於某種原因，這使表單對象進一步混亂，我想使用symfony表單集合。 它全都是命名空間，因此應該不會有類沖突，但是Symfony似乎不喜歡名為Collection的實體。

我將實體重命名為ProductCollection，它解決了嘗試使用嵌入式表單作為集合的問題。

感謝您的建議。
