添加时出现 Symfony EasyAdmin 3.x ManyToMany 错误: .... 字段的 Doctrine 类型为“4"，EasyAdmin 尚不支持该类型

问题描述

我正在尝试使用 easyAdmin 3.x 在两个类之间建立一个简单的 ManyToMany 关系，当我尝试显示实体 CRUD 时，我经常出现此错误:

I'm trying to do a simple ManyToMany relation between two classes with easyAdmin 3.x , when I'm trying to show entity CRUD , I have constantly this error:

salles"的教义类型字段为4"，EasyAdmin 尚不支持.

The Doctrine type of the "salles" field is "4", which is not supported by EasyAdmin yet.

两个实体都存在函数__to string

Th function __to string exist for the both entity

public function __toString()
    {
        return $this->name;
    }

我的 CrudController:

My CrudController:

namespace App\Controller\Admin;

use App\Entity\Batiment;
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractCrudController;


class BatimentCrudController extends AbstractCrudController
{
    public static function getEntityFqcn(): string
    {
        return Batiment::class;
    }


    public function configureFields(string $pageName): iterable
    {
        return [
            'name',
            'salles'

        ];
    }

}

easyadmin 3.x 不管理多条关系吗?

Does easyadmin 3.x don't manage manytomany relations?

是否有特定的方式来管理和显示这些关系?

Is there a particular way to manage and display these relations?

我发现了这个捆绑包，感谢您的帮助！

I discover this bundle and thank you for your help !

推荐答案

在 EasyAdmin 3.x 中，为所有关联映射添加了一个新的专用类型 fied.

In EasyAdmin 3.x a new dedicated type of fied has been added for all association mappings.

请使用以下内容:

namespace App\Controller\Admin;
    
use App\Entity\Batiment;
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractCrudController;
use EasyCorp\Bundle\EasyAdminBundle\Field\AssociationField;
use EasyCorp\Bundle\EasyAdminBundle\Field\Field;
        
        
class BatimentCrudController extends AbstractCrudController
{
    public static function getEntityFqcn(): string
    {
        return Batiment::class;
    }

    public function configureFields(string $pageName): iterable
    {
        return [
            Field::new('id')->hideOnForm(),
            Field::new('name'),
            Field::new('Letter'),
            ImageField::new('image'),
            AssociationField::new('products')
        ];
    }
}
