在cakephp4中如何访问模型中的模型

Question

如何在 cakephp4.2 中访问模型中的另一个模型？关于这个问题的文档对我来说不清楚，然后我可以对此运行查询吗？ TableRegistry 现已弃用。

 error Unknown method "getTableLocator" called on App\Model\Table\LessonsTable  

//none of these no longer work
in model {

use Cake\ORM\Locator\LocatorAwareTrait;


class LessonsTable extends Table
 {
 ..

  private function  getlessonRevenue(){

  //$clients = $this->getTableLocator()->get('Clients');
  // $cleints = TableRegistry::get('Clients'); 
  // $this->Table = TableRegistry::get('Clients');
   $clients = $this->getTableLocator()->get('Clients');

Answer 1

尝试：

<?php

class ArchivesTable extends Table
{

    use \Cake\ORM\Locator\LocatorAwareTrait; // <------------ add here

    public function myMethod()
    {
        $clients = $this->getTableLocator()->get('Clients');
    }

}
