Acl in one-to-many relationship

[rabii]

if i understand you want the only the assigneduser of the parent entity to have access to the child entities. if that is the case you can create a custom ACL for your child entity as below: change parent entity with the parent link id and parent entity name

namespace Espo\Custom\Acl;

use \Espo\Entities\User;
use \Espo\ORM\Entity;

class YourChildEntity extends \Espo\Core\Acl\Base
{
    public function checkIsOwner(User $user, Entity $entity)
    {
        if ($entity->has('parentEntityId')) {

            $parentEntityId = $entity->get('parentEntityId');

            if (!$parentEntityId) return false;

            $parentEntity = $this->getEntityManager()->getEntity('ParentEnity', $parentEntityId);

            if ($parentEntity && $this->getAclManager()->getImplementation('ParentEnity')->checkIsOwner($user, $parentEntity)) {
                return true;
            }

            return false;

        } else {

            return parent::checkIsOwner($user, $entity);

        }

    }

    public function checkInTeam(User $user, Entity $entity)
    {
        if ($entity->has('parentEntityId')) {

            $parentEntityId = $entity->get('parentEntityId');

            if (!$parentEntityId) return false;

            $parentEntity = $this->getEntityManager()->getEntity('ParentEnity', $parentEntityId);

            if ($parentEntity && $this->getAclManager()->getImplementation('ParentEnity')->checkInTeam($user, $parentEntity)) {
                return true;
            }

            return false;

        } else {

            return parent::checkInTeam($user, $entity);

        }
    }
}​ 

and under Espo\Custom\Resources\metadat\app\acl.json define a mapping between the childentity and it is parent entity:

{
    "mandatory": {
        "scopeLevel": {
            "ChildEntity": "ParentEntity"
        }
    }
}​ 

Hope this is what you are looking for.

There are two entities in a one-to-many relationship.
I want the access rights to the child entities to match the parent entity.
How can I do it correctly?

To ensure proper functionality in all cases:
In the case of requesting linked entities: /entity/entityId/linkName
In the case of a simple list query with additional filters.

And without setting additional permissions through roles.
