在 cakephp4 中如何访问模型中的模型

问题描述

如何在 cakePHP4.2 的模型中访问另一个模型？我不清楚有关此问题的文档，然后我可以对此进行查询？ 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');

https://api.cakephp.org/4.0/class-Cake.ORM.TableRegistry.html

解决方法

试试：

<?php
use Cake\ORM\Locator\LocatorAwareTrait; //<------------ add here
class ArchivesTable extends Table
{
  use LocatorAwareTrait; // <--------------------------- and add here
  public function myMethod()
  {
      $clients = $this->getTableLocator()->get('Clients');
  }
