Symfony FormType錯誤

Question

創建提供程序時出現錯誤。

傳遞給選擇字段的實體必須進行管理。 也許將它們保留在實體經理中？

我的formType PrestataireType

/**
 * @var bool $admin
 */
private $admin;

/**
 * @var User $user
 */
private $user;

/**
 * DemandeType constructor.
 * @param bool|false $admin
 */
public function __construct($admin = false, $user, $badges = null)
{
    $this->admin = $admin;
    $this->user = $user;
}

/**
 * {@inheritdoc}
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('files', FileType::class, array(
                'required' => false,
                'attr' => array('class' => 'hidden')
            )
        )
        ->add('name')
        ->add('address')
        ->add('city')
        ->add('zipcode')
        ->add('phone')
        ->add('email')
        ->add('dateStartContract')
        ->add('dateEndContract')
        ->add('frequency')
        ->add('intervention', CollectionType::class, array(
            'entry_type'   => EntityType::class,
            'entry_options'  => array(
                'class'      => 'AppBundle:Intervention',
                'expanded' => false,
                'choice_label' => 'id'
            ),
            'allow_add'    => true,
            'allow_delete' => true,
            'invalid_message' => "Un destinataire n'existe pas",
        ));
    if ($this->user->getResidence() != $this->admin) {
        $builder->add('residence', EntityType::class, array(
            'class' => 'AppBundle:Residence',
            'choices' => $this->user->getResidence(),
        ));
    } else {
        $builder->add('residence', 'entity', array(
            'class' => 'AppBundle:Residence',
            'choice_label' => 'name',
        ));
    }
    ;

謝謝你的幫助。

Answer 1

我認為您需要將字段$ intervention設置為實體中的復數形式：

private $interventions;

然后，您必須在FormType中對此進行匹配：

// ...
->add('interventions', CollectionType::class, array(
// ...

並在您的添加/刪除方法中：

public function addIntervention(\AppBundle\Entity\Intervention $intervention)
{
    $this->interventions[] = $intervention;

    return $this;
}

public function removeIntervention(\AppBundle\Entity\Intervention $interventions)
{
    $this->interventions->removeElement($interventions);
}
