嵌入形式中的Symfony [2.8.9] EntityType未选择值

Question

我有一个Organization实体，它引用一个包含Country实体的嵌入式表单。 表单保存没有问题，但是“国家EntityType”字段在编辑时无法正确获取值，因此，始终选择下拉列表中的第一个选项，而不是正确的选项。

OrganisationType表单：

<?php

namespace AppBundle\Form\Type\Meta;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\FormEvent;
use Symfony\Component\Form\FormEvents;
use Symfony\Component\OptionsResolver\OptionsResolver;

class OrganisationType extends AbstractType
{

    public function __construct()
    {

    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('title', new TitleType(),
                array('required' => true, 'label' => false))
            ->add('country', new CountryType(), array('label' => false))
            ->add('location', 'text',
                array('required' => false, 'label' => 'City'));    
    }

    public function getName()
    {
        return 'organisation';
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'AppBundle\Entity\Organisation',
            'csrf_protection' => true,
            'csrf_field_name' => '_token',
            // a unique key to help generate the secret token
            'intention' => 'organisation',
            'cascade_validation' => true
        ));
    }

}

CountryType表单：

<?php

namespace AppBundle\Form\Type\Meta;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Doctrine\ORM\EntityRepository;

class CountryType extends AbstractType
{

    public function __construct()
    {

    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('id', EntityType::class, array(
                'label' => 'Country',
                'class' => 'AppBundle:Country',
                'choice_label' => 'name',
                'placeholder' => 'Choose an option...',
                'query_builder' => function (EntityRepository $repository) {
                    return $repository->createQueryBuilder('c')->orderBy('c.name', 'ASC');
                }
            ));

    }

    public function getName()
    {
        return 'country';
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'AppBundle\Entity\Country'
        ));
    }

}

    }

    /**

    {
        return $this->dateUpdated;

     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }
}

如果我替换，请在CountryType表单中...

->add('id', EntityType::class, ...

用...

->add('name')

...然后我看到显示的国家名称没有任何问题。 EntityType在哪里出错？

我认为您没有正确使用自定义FormType。 您不应该在自定义FormType中向构建器添加任何内容。 尝试这个 ：

<?php

namespace AppBundle\Form\Type\Meta;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\FormEvent;
use Symfony\Component\Form\FormEvents;
use Symfony\Component\OptionsResolver\OptionsResolver;

class OrganisationType extends AbstractType
{

    public function __construct()
    {

    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('title', new TitleType(),
                array('required' => true, 'label' => false))

            ->add('country', new CountryType(), array(
                'label' => 'Country',
                'choice_label' => 'name',
                'placeholder' => 'Choose an option...',
