Symfony4 Embed form issue - php

Question

I'm learning php and Symfony. I made Ring entity and RingPhoto entity. I want to add a form for RingPhoto inside a form for Ring entity, so I can edit ring information and photo url; ring information will be under Ring entity and photo url will be under Ring photo.
this is Ring entity
'''
/**
* #ORM\OneToMany(targetEntity="Customize\Entity\RingPhoto", mappedBy="ring")
*/
private $ringPhoto;
public function __construct()
{
$this->ringPhoto = new ArrayCollection();
}
/**
* #return Collection|RingPhoto[]
*/
public function getRingPhoto(): Collection
{
return $this->ringPhoto;
}
'''
and this is ringPhoto Entity
'''
/**
* #ORM\ManyToOne(targetEntity="Customize\Entity\Ring", inversedBy="ringPhoto")
*/
private $ring;
public function getRings(): ?Ring
{
return $this->ring;
}
public function setRings(?Ring $ring): self
{
$this->ring = $ring;
return $this;
}
'''
and this is RingPhotoType
'''
class RingPhotoType extends AbstractType
{
/**
* {#inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('image1', FileType::class, [
'label' => 'file1'
])
->add('image2', FileType::class, [
'label' => 'file1'
])
->add('image3', FileType::class, [
'label' => 'file1'
]);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => RingPhoto::class,
]);
}
}
'''
this is Controller
'''
public function UpdateRing($id, Request $request){
$doct = $this->getDoctrine()->getManager();
$rn = $doct->getRepository(Ring::class)->find($id);
if(!$rn){
throw $this->createNotFoundException(
'No Ring found for id.'.$id
);
}
$form = $this->createFormBuilder($rn)
->add('product_group_id', HiddenType::class,['data'=> 1])
->add('ring_name', TextType::class)
->add('ring_type', TextType::class)
->add('ring_shape', TextType::class)
->add('size', ChoiceType::class, array('choices' => array(
'0.5'=>0.5,
'1'=>1,
'1.5'=>1.5,
'2'=>2,
'2.5'=>2.5,
'3'=>3,
'3.5'=>3.5,
'4'=>4,
)))
->add('price', IntegerType::class)
->add('ringPhoto', CollectionType::class,[
'entry_type' => RingPhotoType::class,
'allow_add' => true,
'entry_options' =>[
'label' => false,
],
'allow_add' => true,
'by_reference' => false,
'prototype' => true
])
->add('save', SubmitType::class, ['label' => 'Update'])
->getForm();
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()){
$ring = $form->getData();
$doct = $this->getDoctrine()->getManager();
//tell doctrine to save the product
$doct->persist($ring);
//executes the queries
$doct->flush();
return $this->redirectToRoute('test');
}
else{
return[
'form' => $form->createView(),
];
}
}
'''
and this is the twig
'''
{% extends 'default_frame.twig' %}
{% block main %}
<h3>SamplePage!!</h3>
<div>hello this is Update page</div>
{{form_start(form)}}
{{form_widget(form)}}
{{form_row(form.ringPhoto)}}
{{form_end(form)}}
{% endblock %}
'''
so it's kinda working, having no errors. But in the view, under the price, I can only see the name Ring Photo.
It does not show image1, image2, image3 from RingPhotoType.php that I can fill in :S
how can I fix this issue?

Answer 1

Oh I fixed it.
I added nullable=true to image1, 2, 3 in RingPhoto Entity and somehow it solved the problem
