null値の後に送信されたフォーム

Question

私はこのエラーを持っている：私はページをロードするモーダル使用

An exception occurred while executing 'INSERT INTO skills (name) VALUES (?)' with params [null]:

をx.html.twigにおけるモーダル..page x.html.twigコンテンツ名（SkillType ）とレベル（選択オプション）。

私はこのフォームタイプを有する：

<?php 

     namespace AppBundle\Form\Type; 

     use AppBundle\Entity\CandidateSkill; 
     use Symfony\Component\Form\AbstractType; 
     use Symfony\Component\Form\FormBuilderInterface; 
     use Symfony\Component\OptionsResolver\OptionsResolver; 
     use Symfony\Component\Form\Extension\Core\Type\ChoiceType; 
     use Symfony\Component\Form\Extension\Core\Type\SubmitType; 
     use AppBundle\Form\Type\SkillType; 
     use Symfony\Bridge\Doctrine\Form\Type\EntityType; 


     /** 
     * Class CandidateSkillType. 
     */ 
     class CandidateSkillType extends AbstractType 
     { 
      /** 
      * {@inheritdoc} 
      */ 
      public function buildForm(FormBuilderInterface $builder, array $options) 
      { 
       $builder->add('level', ChoiceType::class, array('choices' => array('Beginner' => 'Beginner', 'Confirmed' => 'Confirmed', 'Senior' => 'Senior', 'Expert' => 'Expert'))) 
       ->add('skill', SkillType::class)->add('Create', SubmitType::class, array('attr' => array('class'=>'skill btn btn-fill btn-rose'))); 
      } 

      /** 
      * {@inheritdoc} 
      */ 
      public function configureOptions(OptionsResolver $resolver) 
      { 
       $resolver->setDefaults(array(
        'data_class' => CandidateSkill::class, 
        'csrf_protection' => 'false', 
        'allow_extra_fields' => 'false', 
       )); 
      } 

      /** 
      * {@inheritdoc} 
      */ 
      public function getBlockPrefix() 
      { 
       return 'appbundle_candidateskill'; 
      } 
     } 

およびSkillTypeである：

<?php 

    namespace AppBundle\Form\Type; 

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

    /** 
    * SkillType. 
    */ 
    class SkillType extends AbstractType 
    { 
     /** 
     * {@inheritdoc} 
     */ 
     public function buildForm(FormBuilderInterface $builder, array $options) 
     { 
      $builder->add('name',null, array('attr' => array('class' => 'form-control','data-id'=>"test"))); 
     } 

     /** 
     * {@inheritdoc} 
     */ 
     public function configureOptions(OptionsResolver $resolver) 
     { 
      $resolver->setDefaults(array(
       'data_class' => 'AppBundle\Entity\Skill', 
       'csrf_protection' => 'false', 
      )); 
     } 

     /** 
     * {@inheritdoc} 
     */ 
     public function getBlockPrefix() 
     { 
      return 'appbundle_skill'; 
     } 
    }

    $(".skill").click(function() {

     return ['form' => $candiateSkill->createView(),'all'=>$this->getHandler()->all()];

012私はUMPとき

/** 
* @param mixed $object 
* @param array $arguments 
*/ 
public function save($object, array $arguments = ['flush' => true]) 
{ 
    $this->em->persist($object); 
    if (true === $arguments['flush']) { 
     $this->em->flush(); 
    } 
} 

：フォームとのgetData作成のための

関数ハンドル：私はます$ form->のgetData（）..dataのダンプ時に

/** 
     * {@inheritdoc} 
     */ 
     public function handle($object, array $parameters, string $method, bool $submited = false, array $options = []) 
     { 
      $options = array_replace_recursive([ 
       'method' => $method, 
       'csrf_protection' => false, 
      ], $options); 
      $form = $this->formFactory->create(get_class($this->formType), $object, $options); 
      if (!$submited) { 
       return $form; 
      } 
      $form->submit($parameters, 'PATCH' !== $method); 

      return $form->getData(); 
     } 

保存

機能nullですin function Post（）in CandidateSkillHandler ..エラーがあります

$this->repository->save($candidateSkill);

Answer 1

devit2017で要求が処理されなかったためにこのフォームが機能しなかったことが判明しました。

これらの行

$request = $this->requestStack->getCurrentRequest(); 
$form->handleRequest($request); 

代わりの

$form->submit($parameters, 'PATCH' !== $method); 

この問題を解決します。
