How to define a storage mapper? about auditor

[DamienHarper]

Hi @bertoost, auditor can be used outside of a Symfony project, that's why it doesn't require an autowired Symfony service for storage mapper.

A storage mapper has to be a closure/callable/invokable. It takes 2 parameters: an entity name and an array of storage services. It must return the storage service (from the provided array) handling the provided entity name.

There was a bug until version 2.4.2 which prevented using invokable classes, it's fixed now.

Let me give you an example:

<?php
namespace App;

use App\Entity\MyEntity1; 
use App\Entity\MyEntity2; 
use App\Entity\MyEntity3; 
use DH\Auditor\Provider\Service\StorageServiceInterface;

/**
 * MyStorageMapper is an invokable class/service
 *
 */
class MyStorageMapper
{
    // the service expects 2 parameters and should return an object 
    // implementing StorageServiceInterface
    public function __invoke(string $entity, array $storageServices): StorageServiceInterface {
        return \in_array($entity, [MyEntity1::class, MyEntity2::class], true) ? $storageServices['db1'] : $storageServices['db2'];
    }
}

Then, if using auditor-bundle, register it as a storage mapper

# config/packages/dh_auditor.yaml
dh_auditor:
    providers:
        doctrine:
            # Invokable service that maps audit events to storage services
            storage_mapper: App\MyStorageMapper

Thanks @DamienHarper ! The storage mapper now works.
I had to report this on the bundle maybe ;-)

Therefore I am now running into this error when running schema-update command of doctrine.

In MappingException.php line 26:

  [Doctrine\Persistence\Mapping\MappingException]
  The class 'App\Entity\Tenant\Student' was not found in the chain configured namespaces App\Entity\Main

The namespace is configured on the second entity-manager which I do correctly map in the storage mapper.
