我就是不能按语言类型对数据排序
有人可以建议解决此问题吗?您可以使用虚拟字段功能按语言类型排序 首先,将此虚拟字段添加到文档模型中:
public $virtualFields = ['Min_LangType' => 'SELECT MIN(type) FROM languages as Language WHERE Language.document_id = Document.id'];
然后,按语言类型按以下方式排序:
$this->Paginator->sort('Document.Min_LangType',__('language'));
非常感谢你!您的虚拟字段是Min_LangType,因此您应该在index.php中使用Document.Min_LangType。我不敢相信答案这么简单!
