Symfony 4: Form as service, inject service : too few arguments - php

Question

I try to get service in my Form, following official instructions:
https://symfony.com/doc/current/form/form_dependencies.html
this is my services.yaml:
services:
# default configuration for services in *this* file
_defaults:
autowire: true # Automatically injects dependencies in your services.
autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.
public: false
class name
App\:
resource: '../src/*'
exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'
class
App\Controller\:
resource: '../src/Controller'
tags: ['controller.service_arguments']
App\Service\:
resource: '../src/Service/*'
App\Form\:
resource: '../src/Form/*'
my form look like this :
<?php
namespace App\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Doctrine\Common\Persistence\ObjectManager;
use App\Entity\Contrat;
use App\Entity\Society;
use App\Entity\Client;
use App\Form\DataTransformer\ClientToNumberTransformer;
use App\Form\DataTransformer\SocietyToNumberTransformer;
class ContratType extends AbstractType{
private $manager;
public function __construct(SocietyToNumberTransformer $manager){ // this is the breakpoint from error
$this->manager = $manager;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('...')
...
;
// Old fashion way for testing only ...
$builder->get('client')->addModelTransformer(new ClientToNumberTransformer($this->manager));
$builder->get('society')->addModelTransformer(new SocietyToNumberTransformer($this->manager));
}
public function configureOptions(OptionsResolver $resolver){
$resolver->setDefaults(array(
'data_class' => Contrat::class,
));
}
It's look-like pretty ... When i test this with postman I get this error :
Too few arguments to function App\Form\ContratType::__construct(), 0
passed in /code/vendor/symfony/form/FormRegistry.php on line 92 and
exactly 1 expected
I don't understand, i found my fomr in autowiring debug command :
php bin/console debug:autowiring
App\Form\ContratType
App\Form\DataTransformer\ClientToNumberTransformer
App\Form\DataTransformer\SocietyToNumberTransformer
and the controller :
public function addContrat(Request $request, FormData $formData){
$em = $this->getDoctrine()->getManager('default');
$data = $formData->getRequestData($request);
var_dump($data);
$contrat = new Contrat;
$form = $this->factory->createBuilder(ContratType::class, $contrat)->getForm();
$form->submit($data);
if($form->isValid()){
$em->persist($contrat);
$em->flush();
return $this->response(
$this->serialize(
$contrat,
['group1']
)
);
}
return $this->response('error', 500);
}
thx for your help.

Answer 1

Try to replace
$form = $this->factory->createBuilder(ContratType::class, $contrat)->getForm();
for
$form = $this->createForm(ContratType::class, $contrat);

I have got the same problem but as I build my form from inside a service, I m still stuck ;-)
Hope it helps
