Doctrine query error unknow column - php

Question

I'm using Doctrine in my Symfony3 project. I'm using the entity manager to get my data from the database but I have an unexpected error which seems to be generated by doctrine.
An exception has been thrown during the rendering of a template ("An exception occurred while executing 'SELECT t0.id AS id_1, t0.date AS date_2, t0.comment AS comment_3, t0.viewed AS viewed_4, t0.error_count AS error_count_5, t0.of_id AS of_id_6, t0.checkpoint_id AS checkpoint_id_7, t8.id AS id_9, t8.name AS name_10, t8.description AS description_11, t8.deleted_at AS deleted_at_12, t8.factory_id AS factory_id_13, t0.operateur_id AS operateur_id_15, t0.factory_id AS factory_id_16 FROM app_check_set t0 LEFT JOIN app_checkpoint t8 ON t0.checkpoint_id = t14.id AND ((t14.deleted_at IS NULL)) WHERE t0.factory_id = ? ORDER BY t0.date DESC LIMIT 5' with params [3]:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 't14.id' in 'on clause'").
As I'm not creating the query myself, i would like to know where is this error coming from ? Is it related with my entity configuration ?
The problem is when I want to get my entities Checkset :
public function notificationsAction(Request $request){
$user = $this->getUser();
$em = $this->getDoctrine()->getManager();
return $this->render('AppBundle:Home:notifications.html.twig', array(
'notifications' => $em->getRepository('AppBundle:CheckSet')->findBy(array('factory' => $user->getFactory()->getId()), array('date' => 'desc'), 5),
'count' => count($em->getRepository('AppBundle:CheckSet')->findBy(array('factory' => $user->getFactory()->getId(), 'viewed' => false)))
));
}
My entities are like this :

The problem could be because of the soft delete but I'm not sure ... The controller I'm calling (notificationsAction) is embed in my header.
In this page (the notifications area) I want to display objects which may have been deleted. The problem happend when the checkpoint I want to display (the one related to the Checkset objects) has been deleted
<!-- NOTIFICATIONS -->
{{ render(controller('AppBundle:Home:notifications', {'request': app.request})) }}

Answer 1

Your issue is actually the same as here.
Your class name is Checkpoint and I guess the file is named checkpoint.php (note that if you are developing on windows, the filename is case-insensitive). All are lowercase.
In your CheckSet class you have
/**
* #ORM\ManyToOne(targetEntity="AppBundle\Entity\CheckPoint", inversedBy="checkSet", fetch="EAGER")
* #ORM\JoinColumn(name="checkpoint_id", referencedColumnName="id")
*/
private $checkPoint;
The targetEntity is to "AppBundle\Entity\CheckPoint" with capital P.
The issue is that because of this, doctrine create a new alias for a new table (the php comparison is case sensitive github link).
To solve this, change your class name and file to CheckPoint with capital P:
class CheckPoint
{
