Symfony API Entity Validation - validation

Question

I have a class with annotations for the validation.
namespace AppBundle\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use JMS\Serializer\Annotation as Serialize;
use Symfony\Component\Validator\Constraints as Assert;
use AppBundle\Annotation\Link;
/**
* #Serialize\ExclusionPolicy("all")
* #Serialize\AccessType(type="public_method")
* #Serialize\AccessorOrder("custom", custom = {"id", "name", "awardType", "nominations"})
* #ORM\Entity(repositoryClass="AppBundle\Repository\AwardRepository")
* #ORM\Table(name="awards")
* #Link("self", route = "api_awards_show", params = { "id": "object.getId()" })
*/
class Award extends Entity
{
/**
* #Serialize\Expose()
* #Serialize\Type(name="string")
* #Assert\Type(type="string")
* #Assert\NotBlank(message="Please enter a name for the Award")
* #Assert\Length(min="3", max="255")
* #ORM\Column(type="string")
*/
private $name;
/**
* #Serialize\Expose()
* #Serialize\Type(name="AppBundle\Entity\AwardType")
* #Serialize\MaxDepth(depth=2)
* #Assert\Valid()
* #ORM\ManyToOne(
* targetEntity="AppBundle\Entity\AwardType",
* inversedBy="awards"
* )
*/
private $awardType;
/**
* #Serialize\Expose()
* #Serialize\Type(name="ArrayCollection<AppBundle\Entity\Nomination>")
* #Serialize\MaxDepth(depth=2)
* #ORM\OneToMany(
* targetEntity="AppBundle\Entity\Nomination",
* mappedBy="award"
* )
*/
private $nominations;
}
I then validate that entity with the following:
$validator = $this->get('validator');
$errors = $validator->validate($entity);
if (count($errors) > 0) {
$apiProblem = new ApiProblem(
400,
ApiProblem::TYPE_VALIDATION_ERROR
);
$apiProblem->set('errors', ['testing', 'array']);
throw new ApiProblemException($apiProblem);
}
$this->save($entity);
This works fine the problem is that i cant get the information on which fields have errors and their error message. $errors in this case seems to be of an unknown type which i cant seem to get the error messages for any fields.
How do i get the error messages of that object?

Answer 1

You can get the exact messages of the errors like this:
$errors = $validator->validate($entity);
if (count($errors) > 0) {
$formattedErrors = [];
foreach ($errors as $error) {
$formattedErrors[$error->getPropertyPath()] = [
'message' => sprintf('The property "%s" with value "%s" violated a requirement (%s)', $error->getPropertyPath(), $error->getInvalidValue(), $error->getMessage());
];
}
return new \Symfony\Component\HttpFoundation\JsonResponse($formattedErrors, 400);
}
For example, that could output:
[
'field1' => 'The property "field1" with value "" violated a requirement (Cannot be null)',
// ...
]
