【问题描述】：

我有文件

/** @MongoDB\ReferenceMany(targetDocument="NewsTag") */ private $tags;

关系。

在我的奏鸣曲管理员中，我想按标签过滤列表。我尝试使用

$datagridMapper->add('tags', null, array(), null, array('expanded' => true, 'multiple' => true))

在文档中，但有一个错误

Could not load type "document"

有人知道为什么吗？

【问题讨论】：

我认为第二个参数null 被猜测为“文档”。尝试将其替换为 dacument 以确认。如果错误消息是关于dacument，我的理论是正确的。此外，您应该提供堆栈跟踪（作为文本，请参阅页面底部）
是的。它猜测为document。我已经在源代码中找到了位置。问题是第二个论点应该是什么。我试过doctrine_mongo_model，但也猜成document/
第四个参数呢？我总是把它们混在一起……
好的，现在我有另一个错误。我尝试$datagridMapper->add('tags', null, [], 'sonata_type_model', ['multiple' => true, 'property' => 'name', 'by_reference' => false])，错误是Catchable Fatal Error: Argument 1 passed to Sonata\AdminBundle\Form\ChoiceList\ModelChoiceLoader::__construct() must implement interface Sonata\AdminBundle\Model\ModelManagerInterface, null given, called in /var/www/meteoprog-site-s3/var/cache/dev/classes.php on line 13150 and defined

【解决方案1】：

因此，如果您想使用 sonata_type_model 进行过滤，则可能会出现错误。您在 ChoiceField 中没有 modelManager。但是您可以像这样在 configureDatagridFilters 中手动添加它：

   $datagridMapper
        ->add('tags', null, [], 'sonata_type_model',
            [
                'model_manager' => $datagridMapper->getAdmin()->getModelManager(), 
                'property' => 'name', 
                'multiple' => true, 
                'by_reference' => false
            ]);
