symfony4 inject parameter in form - php

Question

I have a Business Entity and a BusinessObject Entity, and I would like to link the BusinessObject to the current Business when I create a new BusinessObject.
For example, if my route is business/{id}/object/new, I would like to have the object related with the Business (thanks to the id).
In my BusinessObject Controller, I managed to use #ParamConverter to get the Business id.
In my BusinessObject Form, I put an HiddenType to my business entry because I don't want it to appear, and set data to business_ID.
I struggle in configureOptions to get the business ID, I can't figure out how to get the business id from here.
BusinessObject Controller (route new):
/**
* #Route("/{post_id}/new", name="business_object_new", methods="GET|POST")
* #ParamConverter("business", options={"id" = "post_id"})
*/
public function new(Request $request,Business $business): Response
{
$businessObject = new BusinessObject();
$businessID = $business->getId();
$form = $this->createForm(BusinessObjectType::class, $businessObject,array(
'business_ID'=>$businessID,
));
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($businessObject);
$em->flush();
return $this->redirectToRoute('business_object_index');
}
return $this->render('business_object/new.html.twig', [
'business_object' => $businessObject,
'business'=>$business,
'form' => $form->createView(),
]);
}
BusinessObjectType:
class BusinessObjectType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('object',TextType::class)
->add('complement')
->add('status')
->add('durationExpected')
->add('durationAchieved')
->add('client')
->add('projectManager')
->add('business',HiddenType::class,array(
'data' => $options['business_ID']
))
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => BusinessObject::class,
'business_ID'=>Business::class
]);
}
}
With this code, I get an error Expected argument of type "App\Entity\Business or null", "string" given. I think this have something to do with the function configureOptions() in my Form

The approach can be:
public function new(Request $request,Business $business): Response
{
$businessObject = new BusinessObject();
$form = $this->createForm(BusinessObjectType::class, $businessObject);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
// I suppose your setter is `setBusiness`, otherwise use more suitable one
$businessObject->setBusiness($business);
$em = $this->getDoctrine()->getManager();
$em->persist($businessObject);
$em->flush();
Form builder is:
builder
->add('object',TextType::class)
->add('complement')
->add('status')
->add('durationExpected')
->add('durationAchieved')
->add('client')
->add('projectManager'); // No business field
Another option is to embed BusinessType form into BusinessObjectType, you can read more about form embedding here.
