Symfony: ManyToOne Form Issue - php

Question

I have two entities called, Ticket & TicketUpdate.
Each Ticket can have many TicketUpdates, but every TicketUpdate can only have 1 Ticket.
Next I have a form which shows the current Ticket, but also allows me to add 1 TicketUpdate & change attributes of Ticket.
This is my controller:
//TicketController.php
...
/**
* #Route("/ticket/{id}", name="app_ticket")
*/
public function ticket(Request $request, Ticket $ticket)
{
$ticketUpdate = new TicketUpdate();
$ticketUpdate->setTicket($ticket);
$form = $this->createForm(TicketUpdateType::class, $ticketUpdate); //custom form type
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($ticketUpdate);
$em->persist($ticket);
$em->flush();
}
return $this->render('ticket/view.html.twig', ['ticket' => $ticket, 'form' => $form->createView()]);
}
...
TicketUpdateType:
//TicketUpdateType.php
...
class TicketUpdateType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('text', TextareaType::class, ['label' => 'update', 'required' => false, 'attr' => ['class' => 'textarea-sm'])
->add('ticket', TicketType::class, ['label' => false, 'by_reference' => false]) //custom Type for Tickets
->add('submit', SubmitType::class, ['label' => 'save']);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => TicketUpdate::class
]);
}
}
...
However, this solution does not work for me. Symfony always wants to create a new Ticket entry, instead of changing the old one.
Is there any way to fix this?

Answer 1

May you know, a magic with symfony forms, with you can get an Entity (Ticket), like in your example, I dont know... but this will working:
/**
* #Route("/ticket/{ticketId}", name="app_ticket", requirements={"ticketId"="\d+"})
*/
public function ticket(Request $request, int $ticketId = 0)
{
$em = $this->getDoctrine()->getManager();
$ticket = $em->getRepository(Ticket::class)
->findOneBy([
'id' => $ticketId
]);
if ($ticket instanceof Ticket === false)
{
die('Ticket dont exist with the requested ID.'); #Just return here some error message
}
$ticketUpdate = new TicketUpdate();
//Because your setTicket() setter inside your TicketUpdate Entity
//sure have nullable typehinted argument (?Ticket $ticket)
//if this is a valid doctrine relationship
//(but if i'm wrong, please show the touched parts of your TicketUpdate entity)
$ticketUpdate->setTicket($ticket); #<-- here is an "old" Ticket $ticket
$form = $this->createForm(TicketUpdateType::class, $ticketUpdate); //custom form type
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid())
{
$em->persist($ticketUpdate);
//I'm working a lot with doctrine relationships
//In many time necessary using a setter in the both Entity
$ticket->addTicketUpdate($ticketUpdate); #You know this setter! Change, if my tip wrong
$em->persist($ticket);
$em->flush();
}
return $this->render('ticket/view.html.twig', [
//Now, this is an instance of the Ticket
//not an int ID!
//so if you need the ID, you can get in twig, like:
//{{ ticket.id }}
'ticket' => $ticket, #Or: $ticket->getId()
'form' => $form->createView()
]);
}
The requirements inside the #route means, the method will running only on pages, where the {ticketId} is numeric.

Answer 2

Update: I changed by_reference to true and removed every logic in my TicketType, which seemed to cause the issue.
Atleast for now I got it running. Here is my controller:
//TicketController.php
...
/**
* #Route("/ticket/{id}", name="app_ticket")
*/
public function ticket(Request $request, Ticket $ticket)
{
$ticketUpdate = new TicketUpdate();
$ticketUpdate->setTicket($ticket);
$form = $this->createForm(TicketUpdateType::class, $ticketUpdate); //custom form type
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($ticketUpdate);
//$em->persist($ticket); -> removed, will be automatically updated by symfony
$em->flush();
}
return $this->render('ticket/view.html.twig', ['ticket' => $ticket, 'form' => $form->createView()]);
}
...
