Cakephp - 使用'foreach'显示数据不会返回任何值

Question

I am trying to digest one of cakephp tutorials and yesterday I stuck. The sample website is called Jobfinds, so I have table name "jobs".

Here is the code from JobsController :

    <?php
    namespace App\Controller;

    use App\Controller\AppController;

    class JobsController extends AppController{


    public $name = 'Jobs';

    /*
     * Default Index Method
     */

public function index() {
    //Set Query Options
    $options = array(
        'order' => array('Jobs.created' => 'asc' ),
        'limit' => 4
    ); 

    //Get Job Info

    $jobs = $this->Jobs->find('all', $options);

    $this->set('jobs', $jobs);
  }
}
?>

This code is in index.ctp but it doesn't show anything but it should.

<?php foreach($jobs as $job) : ?>
<p><?php  echo $job['jobs']['title'];
 ?> </p>
<?php endforeach; ?>

When I put for example

<?php echo "something"; ?>

Then 'something' is being displayed so I figured that there must be just a small mistake that is does not fetch data from the table. I was trying for too long. I'm starting loosing my hair because of that. This tutorial is pretty awesome but there is used cakephp 2.x and I am using 3.x. so on every step I need to change something and up till now I succeeded but I stuck with this for good. Anyone can see where is the culprit? Why it doesn't fetch data from the table?

I have no errors in debug LOGS.

print_r($job) inside loop gives as below

    Cake\ORM\Entity Object ( [id] => 1 [category_id] => 7 [user_id] => 1          [type_id] => 1 [company_name] => Tech Guy Computer Services [title] => Senior Graphic Designer [description] =>
