使用TableRegistry获取cakephp3中的所有记录？

My Demo Controller (DemoController.php):

<?php

namespace App\Controller;
class DemoController extends AppController
    {
       public function users()
        {
            $this->loadmodel('registration');
            $result = $this->registration->getAllUsers();
            $this->set('user_data',$result)
        }
    }
?>

My registration model (registration.php):

<?php
namespace App\Model;

use Cake\ORM\TableRegistry;

class Registration extends AppModel {

    $articles = TableRegistry::get('registration');

    public function getAllUsers()
        {
            return $query = $articles->find();
        }

}
?>

My View:

path -- src/Template/Demo/users.ctp

but it's getting error like this (in below image) --

Your model should be named RegistrationsTable, and be in src/Model/Table/RegistrationsTable.php. Load it with loadModel('Registrations'). (It's your entity that should be named Registration.) To use your custom finder method, name the function findAllUsers, fix the signature per the documentation (should take two parameters: Query $query, array $options) and call it as $this->Registration->find('all_users');.

And why are you trying to initialize a $articles variable as the registrations model inside the registrations model (but outside of any function)? So much mess...
