Description
Hi, I noticed that ItemNormalizer doesn't support denormalizing of IRI string. I have an issue, probably related to #2036, with deserializing entity with type hinted constructor. For example if we have User and Group entities which are exposed as API resources:
/**
* @ApiResource
*/
class User {
/**
* @var string
*/
private $username;
/**
* @var Group
*/
private $group;
public function __construct(string $username, Group $group)
{
$this->username = $username;
$this->group = $group;
}
....
}
/**
* @ApiResource
*/
class Group {
/**
* @var string
*/
private $name;
public function __construct(string $name) { ... }
}Sending POST to /users request with payload:
{
"username": "test",
"group": "/groups/123456" // already persisted group
}
This leads to exception when symfony AbstractNormalizer trying to denormalize $group argument to the Group resource from string /groups/123456. Actually ItemNormalizer is used to denormalize IRI string but it doesn't trying to load resource from IRI converter like it does for array with id field here .
As a workaround currently I'm using extended ItemNormalizer
final class ResourceItemNormalizer extends ItemNormalizer
{
public function denormalize($data, $class, $format = null, array $context = [])
{
// fix issue denormalizing of the IRI string into resource object (for example as constructor argument)
if (is_string($data) && !isset($context[ItemNormalizer::OBJECT_TO_POPULATE])) {
return $this->iriConverter->getItemFromIri($data, $context + ['fetch_data' => true]);
}
return parent::denormalize($data, $class, $format, $context);
}
}I'm using the latest api-platform/core:2.3
