Question

我正在使用Symfony 4和Sonata Admin。我试图在FormBuilder中使用CollectionType在管理控制台中创建订单，但出现此错误：

Warning: spl_object_hash() expects parameter 1 to be object, array given

我知道这是什么意思，但是我找不到解决方法：（

OrderAdmin

namespace App\Admin;

use Sonata\AdminBundle\Admin\AbstractAdmin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Form\FormMapper;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Sonata\AdminBundle\Form\Type\ModelListType;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use App\Entity\User;
use App\Entity\OrderProduct;
use App\Form\Type\OrderProductFormType;

class OrderAdmin extends AbstractAdmin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper->add('state', ChoiceType::class, array(
          'choices'  => array(
            'PROCESSING' => 'PROCESSING',
            'DONE' => 'DONE'
          )
        ));
        $formMapper->add('user', EntityType::class, [
            'class' => User::class
        ]);
        $formMapper->add('orderProducts', CollectionType::class, array(
          'entry_type' => OrderProductFormType::class,
          'allow_add' => true,
          'allow_delete' => true
        ));
    }
?>

OrderProductFormType

<?php

namespace App\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\IntegerType;
use App\Entity\Product;
use App\Entity\Size;
use App\Entity\Material;
use App\Entity\Shape;

class OrderProductFormType extends AbstractType
{
   public function buildForm(FormBuilderInterface $builder, array $options)
   {
      $builder->add('product', EntityType::class, [
       'class' => Product::class
      ]);
      $builder->add('quantity', IntegerType::class);
      $builder->add('size',EntityType::class, [
       'class' => Size::class,
       'required' => false
      ]);
      $builder->add('shape', EntityType::class, [
       'class' => Shape::class,
       'required' => false
      ]);
      $builder->add('material', EntityType::class, [
       'class' => Material::class,
       'required' => false
      ]);
    }

   public function getBlockPrefix()
   {
     return 'app_order_product';
   }
}

订购

我了解他在需要对象时会收到一个数组，但是为什么我得到一个数组而不是带有CollectionType字段的对象OrderProduct？也许我有事要做以覆盖此结果？

感谢您浏览我的帖子！

警告：spl_object_hash（）期望参数1为对象，给定数组-Sonata Admin
