Question

我在Customer，Formation和Theme实体之间有很多关系。客户的插入形式无效。

我解释了我想做什么：我想通过添加一个或多个“格式”和一个或多个“主题”来添加“客户”，因为他们知道主题与“格式”相关，即客户是否拥有Training_1，他将无法从队形_2获得主题。

所有代码都在那里。

客户实体：

形成实体：

CustomerType（客户形式）：

<?php

namespace App\Form;

use App\Entity\Customer;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\FormEvent;
use Symfony\Component\Form\FormEvents;

use App\Form\Type\DateTimePickerType;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;

class CustomerType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('customerName', null, array(
                    'label'    => 'Domaine du client ',
                    'required' => true)
            )
            ->add('enabled', null, array(
                'label'    => 'Activer la formation'), [
                'required'   => false,
            ])
            ->add('formations', EntityType::class, [
                'class' => "App\Entity\Formation",
                'choice_label' => 'name',
                'multiple' => true,
                'expanded' => true,
            ])
            ->add('themes', EntityType::class, [
                'class' => "App\Entity\Theme",
                'choice_label' => 'name',
                'multiple' => true,
                'expanded' => true,
            ])
            ->add('startDate', DateTimePickerType::class, [
                'label' => 'Date de début de la formation',
            ])
            ->add('endDate', DateTimePickerType::class, [
                'label' => 'Date de fin de la formation',
            ]);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => Customer::class,
            'customerName' => null
        ]);
    }
}

我遇到以下错误：

“ App \ Entity \ Theme”类型的预期参数，属性路径中给出的“ Doctrine \ Common \ Collections \ ArrayCollection” “主题”。

您知道此错误来自何处吗？谢谢

Answer 1

在客户实体的构造函数中，您缺少“主题”数组集合的初始化。

在属性路径“主题”中给出的类型为“ App \ Entity \ Theme”，“ Doctrine \ Common \ Collections \ ArrayCollection”的预期参数
