是否可以在configureOptions中动态设置data_class?

Is it possible to dynamically set data_class in configureOptions?

我正在尝试重构一些错误的代码,目前我有超过 20 个表单(字典),其中包含一个名为 name 的字段,以及两个类似的表单(字典),其中包含额外的字段。

这些表单作为集合嵌入到另一种表单中,其中 entry_type 根据从我的工厂返回的值动态设置为以前的表单之一。

目的是在编辑其他一些表单时修改选择,以便用户可以使用新的 button/delete 按钮自由添加或删除选项。

我试图通过创建一个包含单个字段的基本表单来删除我的 20 个表单 - name 并在 configureOptions 中动态配置 data_class 但我找不到这样做的方法。当我尝试修改构造函数并在那里设置值时,我无法在 createForm 期间访问构造函数 - 我只能传递选项,但在 configureOptions.[= 中无法访问选项23=]

我通过 $this->createForm(new FormType($option))

发现在旧版本的 symfony 中是可能的

是否可以在 symfony 5 中做类似的事情?如果不是,解决方法是什么?

如果我能改进问题,请告诉我。这是代码:

操作:

/**
 * @Route("/dictionary/getForm/{id}",
 *     name="dictionary_form")
 * @param $id
 */    
public function getDictionaryView(Request $request, EntityManagerInterface $em, $id){

    $repository = $em->getRepository('App:'.substr($id, 3));
    $items = $repository->findAll();
    
    $form = $this->createForm(DictionaryCollectionType::class,['dictionary' => $items],array(
        'type' => DictionaryFormFactory::createForm($id),
        'action' => $id,
    ));

    $form->handleRequest($request);

    if($form->isSubmitted() && $form->isValid()){

        $data = $form->getData()['dictionary'];
        $idsForm = array_map(function($item) {return $item->getId();},$data);
        foreach($items as $item) {
            if(!in_array($item->getId(),$idsForm)) $em->remove($item);
        }

        foreach($data as $entity) {
            $em->persist($entity);
        }

        $em->flush();

        $return = [];
        foreach($data as $entity) {
            $append = ['value' => $entity->getId(), 'name' => $entity->getName()];
            if($entity instanceof DegreesDisciplines) $append['field'] = $entity->getField()->getId();
            $return[] = $append;
        }

        return new JsonResponse($return);

    }

    return $this->render('Admin\Contents\dictionary.html.twig', [
        'form' => $form->createView()
    ]);
}

(想法)基本形式:

<?php

namespace App\Form\Dictionaries;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\TextType;

class NewDictionaryType extends AbstractType {

    private $data_class;

    public function __construct($data_class)
    {
        $this->data_class = $data_class;
    }
    
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name', TextType::class, [
            'label' => 'Nazwa',
        ]);
    }

    /**
     * @param OptionsResolver $resolver
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => $this->data_class,
        ]);
    }
}

重复的示例表格。其他形式基本只有'data_class'变化:

<?php

namespace App\Form\Dictionaries;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\TextType;

class NewNoticesTypeType extends AbstractType {
    
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name', TextType::class, [
            'label' => 'Nazwa',
            'required' => false,
        ]);
    }

    /**
     * @param OptionsResolver $resolver
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => 'App\Entity\NoticesTypes',
        ]);
    }
}

家长形式:

<?php

namespace App\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;

class DictionaryCollectionType extends AbstractType {

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('dictionary', CollectionType::class, [
            'entry_type' => $options['type'],
            'entry_options' => array('label' => false),
            'empty_data' => null,
            'allow_add'    => true,
            'allow_delete' => true,
            'label' => false,
        ])
        ->add('save', SubmitType::class, [
            'attr' => ['class' => 'save btn btn-success mt-2', 'data-toggle' => 'modal', 'data-target' => '#dictionaryBackdrop', 'action' => $options['action']],
        ]);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => null,
            'type' => null,
            'action' => null
        ));
    }
}

不要使用构造函数来传递配置选项,而只是使用createForm来传递选项:

$form = $this->createForm(DictionaryCollectionType::class,['dictionary' => $items],array(
    'type' => DictionaryFormFactory::createForm($id),
    'action' => $id,
    'data_class' => $dataClass // <-- put your data class (FQCN) here
));

请参阅 Symfony 关于 Passing Options to Forms

的文档

您可能应该重构的另一件事是 'App:'.substr($id, 3)。最好使用 FQCN 而不是旧的 Bundle:Entity 格式。
