Why assertion skips to validate my symfony5 form username field? - php

Question

my problem concerns one field from User form, namely Username. Since assertion validation works for other fields in the entity I find it odd to behave like this - skipping the Assertion rule I did point for username attribute in User entity and passing null attribute to userFormNewHandler which is generating an error, especially when I find it not really different than other fields. I wonder, what am I missing?
UserType.php:
<?php
namespace App\UserBundle\Form\Type;
use App\UserBundle\Entity\User;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
use Symfony\Component\Form\Extension\Core\Type\PasswordType;
use Symfony\Component\Form\Extension\Core\Type\RepeatedType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Validator\Constraints\NotBlank;
class UserType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('username', TextType::class, ['required'=>true,
'invalid_message' => 'Username must not be empty!'])
->add('plainPassword', RepeatedType::class, array(
'type' => PasswordType::class,
'mapped' => false,
'first_options' => array('label' => 'New password'),
'second_options' => array('label' => 'Confirm new password'),
'invalid_message' => 'The password fields must match.',
'required' => true,
'constraints' => [
new NotBlank([
'message' => 'Password field must not be blank!'
])]
))
->add('active_status', ChoiceType::class, [
'choices' => [
'Active' => true,
'Inactive' => false,
],])
->add('first_name',TextType::class, [
'required'=>true, 'invalid_message' => 'First name must not be empty!'])
->add('last_name', TextType::class, [
'required'=>true, 'invalid_message' => 'Last name must not be empty!'])
->add('email', EmailType::class, [
'required'=>true, 'invalid_message' => 'Email must not be empty!']);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => User::class,
]);
}
}
And this is my User.php entity:
<?php
namespace App\UserBundle\Entity;
use App\UserBundle\Repository\UserRepository;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\PasswordAuthenticatedUserInterface;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity(repositoryClass=UserRepository::class)
*/
class User implements UserInterface, PasswordAuthenticatedUserInterface
{
/**
* #ORM\Id
* #ORM\GeneratedValue
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="string", length=180, unique=true)
* #Assert\NotBlank(message="Fill username field")
*/
private $username;
/**
* #ORM\Column(type="json")
*/
private $roles = [];
/**
* #var string The hashed password
* #ORM\Column(type="string")
*/
private $password;
/**
* #ORM\Column(type="boolean")
*/
private $active_status;
/**
* #ORM\Column(type="string", length=30)
* #Assert\NotBlank(message="Fill first name field")
*/
private $first_name;
/**
* #ORM\Column(type="string", length=30)
* #Assert\NotBlank(message="Fill last name field")
*/
private $last_name;
/**
* #ORM\Column(type="string", length=40)
* #Assert\NotBlank(message="Fill email field")
*/
private $email;
/**
* Representation of account status
*/
public function getActiveStatus(): bool
{
return $this->active_status;
}
/**
* Setting account status
*/
public function setActiveStatus(bool $active_status): self
{
$this->active_status = $active_status;
return $this;
}
/**
* Representation of username
*/
public function getUsername(): string
{
return (string) $this->username;
}
/**
* Setting username for user
*/
public function setUsername(string $username): self
{
$this->username = $username;
return $this;
}
//...
and also _form.html.twig, where form is being rendered:
{{ form_start(form, { attr: {novalidate: 'novalidate'} }) }}
{{ form_widget(form) }}
<button class="btn" >{{ button_label|default('Save') }}</button>
{{ form_end(form) }}

Answer 1

I found it! That was because I did point out in setter Username's method to look strictly for string and I guess that prevented me from passing null attribute to the form. Now PHP validation works correctly :)
Part generating error:
User.php
/**
* Setting username for user
*/
public function setUsername(string $username): self
{
$this->username = $username;
return $this;
}
Fix:
/**
* Setting username for user
*/
public function setUsername($username): self
{
$this->username = $username;
return $this;
}
