How to create query builder was failed in CakePHP 3.7 - cakephp-3.7

Question

I'm setting up query builder in CakePHP 3.7 to get value in single row, inside UsersTable. I want to get row value "where Name = 'Budi'"
I'm tried to solved it by browsing in https://book.cakephp.org/3.0/en/orm/query-builder.html but doesn't work
<?php
//UsersController.php
namespace App\Controller;
use App\Controller\AppController;
use App\Model\Table\UsersTable;
use Cake\Event\event;
use Cake\I18n\Time;
use Cake\ORM\TableRegistry;
class UsersController extends AppController
{
public function index
{
$query = $users->find()
->select(['ID', 'Nama'])
->where(['Nama =' => 'Budi']);
foreach ($query as $users) {
debug($users->Nama);
}
$this->set(compact('users'));
}
//code from cake bake all
}
?>
the messages error shown here

An Internal Server Error Occurred
I expect the output is
-------------------------------------------------
| Nama | Role | Dibuat | Diubah |
-------------------------------------------------
| Budi | Visitor | 10/04/2019 | 12/04/2019 |
-------------------------------------------------

Answer 1

You need to reference the model of the controller as well
Use
$query = $this->Users->find()
->select(['ID', 'Nama'])
->where(['Nama =' => 'Budi']);

Answer 2

on first line of index function, i think you must define $users variable
$users = TableRegistry::get('Users');
