Question

我在symfony 4.1项目中使用了Sonata以下软件包：

"sonata-project / admin-bundle": "^ 3.36",
"sonata-project / doctrine-orm-admin-bundle": "^ 3.6",

管理工作正常，除了当我不得不删除引发该错误的记录时。列出，编辑或创建新文件时，没有问题。

这些是我的奏鸣曲配置文件：

[sonata_admin.yml]

sonata_admin:
    title: 'Administración'
    search: false
    dashboard:
        blocks:
            - { type: sonata.admin.block.admin_list, position: left }
    security:
        role_admin: ROLE_ADMINISTRADOR

sonata_block:
    blocks:
        sonata.admin.block.admin_list:
            contexts: [admin]

[sonata_core.yml]

sonata_core:
    form:
        mapping:
            enabled: false

我为要在此处管理的每个实体创建了一个控制器，我留下最清楚的例子：

[EntidadAdmin]

class EntidadAdmin extends _Admin_
{
    /**
     * {@inheritDoc}
     */
    public static function getEntity()
    {
        return Entidad::class;
    }

    /**
     * @param FormMapper $formMapper
     */
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper->with('label.principal', ['class' => 'col-md-7'])
            ->add('nombre', Type\TextType::class, [
                'label' => 'label.nombre'
            ])
            ->add('descripcion', Type\TextareaType::class, [
                'label' => 'label.descripcion',
                'required' => false
            ])->end()->with('label.nomencladores',['class' => 'col-md-5'])
            ->add('nomencladores', EntityType::class, [
                'class' => Nomenclador::class,
                'multiple' => true,
                'required' => false,
                'label' => 'label.nomencladores'
            ])->end();

    }

    /**
     * {@inheritDoc}
     * @throws \RuntimeException
     */
    protected function configureListFields(ListMapper $listMapper)
    {
        $listMapper
            ->addIdentifier('nombre', self::LIST_TYPE_STRING, [
                'label' => 'label.nombre'
            ])
            ->add('nomencladores', self::LIST_TYPE_MANY_TO_ONE, [
                'label' => 'label.nomencladores'
            ]);

        return parent::configureListFields($listMapper);
    }
}

            ->get('doctrine.orm.entity_manager')
            ->getRepository($class)->find($id);;
    }
}

这是具体的错误消息：

不管理实体ACCION。如果实体是从数据库中获取的，或者通过EntityManager＃persist

注册为新实体，则将对其进行管理

我试图覆盖类Sonata \ AdminBundle \ Admin \ AdminAbstract的getObject并删除方法，以为该模型是通过不正确的方式获得的，但仍然给出相同的错误

示例：

public function delete($object)
{
    $em = $this->getContainer()->get('doctrine.orm.entity_manager');
    $toDel = $em->getRepository(self::getEntity())->find($object->getId());
    parent::delete($toDel);
}

public function getObject($id)
{
    $container = $this->getConfigurationPool()->getContainer();
    $em = $container->get('doctrine.orm.entity_manager');
    $object = $em->getRepository(self::getEntity())->find($id);

    foreach ($this->getExtensions() as $extension) {
        $extension->alterObject($this, $object);
    }
    return $object;
}

我修改了数据库中的一条记录并将其转储，并检查该模型是否已从数据库中获取，所以我不明白为什么它告诉我尚未从数据库中获得该记录

对不起，我的英语，欢迎您的帮助； P

奏鸣曲为何向我发送此错误：实体不受管理？
