OneToMany relation generates no field in form

[devbieres]

Hi,

I have a main entity with a translation. In the Translation Entity, there is a relation OneToMany with another entity. Several translated entities may be associated with same relation entities:

• [EN - FR - IT] --> RelationEntityA,
• [DE - ES] --> RelationEntityB,
• [...] --> ?

When rendering the form, there is no field for this relation.

Here is the definition of the relation :

**
* @ORM\OneToMany(targetEntity="App\Entity\SolutionImages", mappedBy="solutionTranslation", orphanRemoval=true)
* @var Collection
*/
private $solutionImages;

In the main entity type, I simply add

 ->add('translations', TranslationsType::class)

Thanks for your help.

For information, I have try to use a EntityType for this field :

 ->add('translations', TranslationsType::class, [
                'fields' => [
                    'label' => [ 'field_type' => TextType::class],
                    'description' =>  [ 'field_type' => TextareaType::class],
                    'solutionImages' => [
                        'field_type' => EntityType::class,
                        'class' => SolutionImages::class
                     ]
                ]
            ])

But it raised an error :

An error has occurred resolving the options of the form "Symfony\Bridge\Doctrine\Form\Type\EntityType": The options "allow_add", "entry_options", "entry_type" do not exist.
