Softdeleteable In Relation

by ADMIN 27 views

Introduction

In the context of Doctrine and DHAuditor, softdeleteable entities can sometimes cause issues when dealing with ManyToOne relations. Specifically, when changing a ManyToOne relation to point to a soft-deleted entity, the AuditTrait may attempt to load the entity, resulting in an EntityNotFoundException. In this article, we will delve into the issue, explore potential solutions, and discuss whether opening a bug issue is necessary.

Understanding Softdeleteable Entities

Softdeleteable entities are a feature in Doctrine that allows entities to be marked as deleted without actually deleting them from the database. This is achieved by adding a "deletedAt" column to the entity's table and setting it to the current timestamp when the entity is deleted. When a softdeleteable entity is retrieved, Doctrine will automatically filter out deleted entities, unless the "softdeleteable" option is disabled.

The Issue with ManyToOne Relations

When a ManyToOne relation is changed to point to a soft-deleted entity, the AuditTrait in DHAuditor attempts to load the entity. However, since the entity is soft-deleted, Doctrine will not load it, resulting in an EntityNotFoundException. This issue can be particularly problematic when dealing with complex relationships between entities.

Potential Solutions

  1. Disable Softdeleteable Option

One potential solution to this issue is to disable the softdeleteable option when loading the entity. This can be achieved by surrounding the line where the AuditTrait attempts to load the entity with a softdeleteable disable/enable statement. This will allow the entity to be loaded, even though it is soft-deleted.

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="my_entity")
 * @ORM\SoftDeleteable
 */
class MyEntity
{
    // ...
}

// In your controller or service
$entityManager = $this->getDoctrine()->getManager();
$entityManager->getConfiguration()->setSoftDeleteable(false);
$entity = $entityManager->getRepository(MyEntity::class)->find($id);
  1. Use a Custom Repository

Another potential solution is to create a custom repository for the entity that loads the entity with the softdeleteable option disabled. This can be achieved by creating a custom repository class that extends the default repository class.

use Doctrine\ORM\EntityRepository;

class MyEntityRepository extends EntityRepository
{
    public function findWithSoftDeleteableDisabled($id)
    {
        $entityManager = $this->getEntityManager();
        $entityManager->getConfiguration()->setSoftDeleteable(false);
        return $entityManager->getRepository(MyEntity::class)->find($id);
    }
}
  1. Open a Bug Issue

If none of the above solutions work for you, it may be necessary to open a bug issue with the DHAuditor team. This will allow them to investigate the issue and potentially provide a fix or a workaround.

Conclusion

In conclusion, softdeleteable entities can sometimes cause issues when dealing with ManyToOne relations in Doctrine and DHAuditor. However, there are potential solutions available, including disabling the softdeleteable option and using a custom repository. If none of these solutions work for you, it may be necessary to open a bug issue with the DHAuditor team.

Q: What is the purpose of softdeleteable entities in Doctrine?

A: Softdeleteable entities in Doctrine allow entities to be marked as deleted without actually deleting them from the database. This is achieved by adding a "deletedAt" column to the entity's table and setting it to the current timestamp when the entity is deleted. When a softdeleteable entity is retrieved, Doctrine will automatically filter out deleted entities, unless the "softdeleteable" option is disabled.

Q: What is the issue with ManyToOne relations and softdeleteable entities?

A: When a ManyToOne relation is changed to point to a soft-deleted entity, the AuditTrait in DHAuditor attempts to load the entity. However, since the entity is soft-deleted, Doctrine will not load it, resulting in an EntityNotFoundException.

Q: How can I disable the softdeleteable option when loading an entity?

A: You can disable the softdeleteable option when loading an entity by surrounding the line where the AuditTrait attempts to load the entity with a softdeleteable disable/enable statement. This will allow the entity to be loaded, even though it is soft-deleted.

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="my_entity")
 * @ORM\SoftDeleteable
 */
class MyEntity
{
    // ...
}

// In your controller or service
$entityManager = $this->getDoctrine()->getManager();
$entityManager->getConfiguration()->setSoftDeleteable(false);
$entity = $entityManager->getRepository(MyEntity::class)->find($id);

Q: Can I use a custom repository to load entities with the softdeleteable option disabled?

A: Yes, you can create a custom repository for the entity that loads the entity with the softdeleteable option disabled. This can be achieved by creating a custom repository class that extends the default repository class.

use Doctrine\ORM\EntityRepository;

class MyEntityRepository extends EntityRepository
{
    public function findWithSoftDeleteableDisabled($id)
    {
        $entityManager = $this->getEntityManager();
        $entityManager->getConfiguration()->setSoftDeleteable(false);
        return $entityManager->getRepository(MyEntity::class)->find($id);
    }
}

Q: Should I open a bug issue with the DHAuditor team if none of the above solutions work for me?

A: Yes, if none of the above solutions work for you, it may be necessary to open a bug issue with the DHAuditor team. This will allow them to investigate the issue and potentially provide a fix or a workaround.
