SonataBlock - 添加输入 ModelListType

如何解决SonataBlock - 添加输入 ModelListType

您好，可以在自定义块中使用 SonataAdmin 输入

我创造

class ArticleBlock extends AbstractAdminBlockService
{

 public function buildEditForm(FormMapper $formMapper,BlockInterface $block)
    {

  $formMapper->add('settings',ImmutableArrayType::class,[
            'keys' => [

              ['article',ModelListType::class,[
                    'class'=>Article::class,'required' => true,'label' => 'Article',]],

但是得到

Argument 1 passed to Sonata\AdminBundle\Form\DataTransformer\ModelToIdTransformer::__construct() must implement interface Sonata\AdminBundle\Model\ModelManagerInterface,null given,called in /application/vendor/sonata-project/admin-bundle/src/Form/Type/ModelListType.PHP on line 53
