afterRemove hook

[zerosix]

I have 3nentities 'A','B','C' A is linked to both of them with one-many (2 links ab, ac), how to set up please a afterRemove hook to delete All the retaled Bs linked to an A after removing a A?
thank you so much
is this code correct?

<?php

namespace Espo\Custom\Hooks\A;

use Espo\ORM\Entity;

class AfterRemove extends \Espo\Core\Hooks\Base
{
public static $order = 10;

public function afterRemove(Entity $entity)
{
$entityManager = $this->getEntityManager();

// Get related 'B' entities
$relatedBs = $entityManager->getRepository('B')->where([
'aId' => $entity->id
])->find();

// Delete each related 'B' entity
foreach ($relatedBs as $bEntity) {
$entityManager->removeEntity($bEntity);
}
}
}

Don't extend from Hooks\Base. It's been as deprecated for a reason for long. See the documentation on hooks Use an IDE.

Removal of entities seems to be correct.

thank you yuri for your guidance, i will share the final code on next answer

if i remove extends \Espo\Core\Hooks\Base i got 500 error

Situation: I have 2 entities 'AAA','BBB', AAA is linked to BBB with one-many, i want to setup a afterRemove hook to delete All the retaled BBB linked to an AAA after removing a AAA.

Solution:

Step 1: Create a Custom Hook File
First, create a custom hook file for the AAA entity. This file should be located in your EspoCRM's custom directory to ensure it's not overwritten by updates. The directory structure would look like: custom/Espo/Custom/Hooks/AAA/AfterRemove.php

Step 2: Implement the Hook
Inside AfterRemove.php, implement the hook as follows:

<?php

namespace Espo\Custom\Hooks\AAA;

use Espo\ORM\Entity;

class AfterRemove extends \Espo\Core\Hooks\Base
{
    public static $order = 10;

    public function afterRemove(Entity $entity)
    {
        $entityManager = $this->getEntityManager();

      
        $relatedBBBs = $entityManager->getRepository('BBB')->where([
            'aAAId' => $entity->id  // Assuming 'aAAId' is the field on BBB that links to AAA
        ])->find();

        // Remove each related BBB entity
        foreach ($relatedBBBs as $bbbEntity) {
            $entityManager->removeEntity($bbbEntity);
        }
    }
}
​
​

Step 3: Clear Cache

[yuri]

For whomever reading it in the future, do not extend \Espo\Core\Hooks\Base.

if i remove extends \Espo\Core\Hooks\Base i got 500 error

[rabii]

try this instead, it all in the documentation

<?php

namespace Espo\Custom\Hooks\AAA;

use Espo\Core\Hook\Hook\AfterRemove;

use Espo\ORM\Entity;
use Espo\ORM\EntityManager;
use Espo\ORM\Repository\Option\RemoveOptions;

/**
 * @implements AfterRemove<AAA>
 */
class RemoveBEntities implements AfterRemove
{
    public static $order = 10;

    public function __construct(private EntityManager $entityManager) {}

    public function afterRemove(Entity $entity, RemoveOptions $options): void
    {
        $relatedBBBs = $this->entityManager
                    ->getRDBRepository('BBB')
                    ->where([
                        'aAAId' => $entity->getId()
                    ])
                    ->find();
        if (!count($relatedBBBs)) {
            return;
        }

        // Remove each related BBB entity
        foreach ($relatedBBBs as $bbbEntity) {
            $this->entityManager->removeEntity($bbbEntity);
        }
    }
}​

thank you so much rabii, i tried it it's giving me error 500

[rabii]

share your code to verify it, also check what error in the log.

[zerosix]

thank you rabii, i have just posted the code+error log,

[zerosix]

Thank you Rabii, the code is

<?php

namespace Espo\Custom\Hooks\AAA;

use Espo\Core\Hook\Hook\AfterRemove;

use Espo\ORM\Entity;
use Espo\ORM\EntityManager;
use Espo\ORM\Repository\Option\RemoveOptions;

/**
 * @implements AfterRemove<AAA>
 */
class RemoveBEntities implements AfterRemove
{
    public static $order = 10;

    public function __construct(private EntityManager $entityManager) {}

    public function afterRemove(Entity $entity, RemoveOptions $options): void
    {
        $relatedBBBs = $this->entityManager
                    ->getRDBRepository('BBB')
                    ->where([
                        'aAAId' => $entity->getId()
                    ])
                    ->find();
        if (!count($relatedBBBs)) {
            return;
        }

        // Remove each related BBB entity
        foreach ($relatedBBBs as $bbbEntity) {
            $this->entityManager->removeEntity($bbbEntity);
        }
    }

mate, you have to change the names to the correct name of your entities.

what are the names of the your entities ? you can find the correct name under administration > entity manager > your entity

[zerosix]

I know chef, the names are AAA and BBB (entities for test)

[rabii]

It can't be (the name of entities is capitalised e.g Account - Contact etc) so the name can't be AAA and BBB - it should be Aaa and Bbb

[rabii]

the error manfest this properly (Error: get_class_methods(): Argument #1 ($object_or_class) must be an object or a valid class name, string given) retrieving a class AAA doesn't work because there is no class called AAA

[zerosix]

so Why this code is working:
<?php

namespace Espo\Custom\Hooks\AAA;

use Espo\Core\Hook\Hook\AfterRemove;

use Espo\ORM\Entity;
use Espo\ORM\EntityManager;
use Espo\ORM\Repository\Option\RemoveOptions;

/**
* @implements AfterRemove<AAA>
*/
class RemoveBEntities implements AfterRemove
{
public static $order = 10;

public function __construct(private EntityManager $entityManager) {}

public function afterRemove(Entity $entity, RemoveOptions $options): void
{
$relatedBBBs = $this->entityManager
->getRDBRepository('BBB')
->where([
'aAAId' => $entity->getId()
])
->find();
if (!count($relatedBBBs)) {
return;
}

// Remove each related BBB entity
foreach ($relatedBBBs as $bbbEntity) {
$this->entityManager->removeEntity($bbbEntity);
}
}
}

[rabii]

it is the same code. not sure what you mean

[zerosix]

yes it's working , i am so sorry🙏🙏🙏🙏, i was confused

[AlessioMa]

Hi everyone
How can I delete an entity from a many-to-one relationship?
