### Configure Doctrine Connected Resources with Query Create Filter

Source: https://github.com/laminas-api-tools/api-tools-doctrine/blob/2.5.x/README.md

This configuration example demonstrates how to link a resource (e.g., Api\V1\Rest\....) to a specific query create filter ('entity_name') within the 'doctrine-connected' section of the 'api-tools' configuration.

```php
'api-tools' => [
    'doctrine-connected' => [
        'Api\\V1\\Rest\\....' => [
            'query_create_filter' => 'entity_name',
            ...
        ],
    ],
],
```

### Using Multiple Keys as Entity Identifier in API Calls

Source: https://github.com/laminas-api-tools/api-tools-doctrine/blob/2.5.x/docs/RELEASE-0.3.3.md

This example shows how to define and use multiple fields as an entity identifier by leveraging a delimiter (defaulting to '.'). This allows for API calls to identify resources using combinations of fields that may not be direct entity identifiers.

```php
'entity_identifer_name' => 'email.shop'
```

```php
'api-tools' => [
    'doctrine-connected' => [
        'Api\V1\Rest\User\UserResource' => [
            // ...
            'listeners' => [
                'key.of.aggregate.listener.in.service_manager',
            ],
        ],
    ],
],
```

```php
'api-tools' => [
    'doctrine-connected' => [
        'Api\V1\Rest\....' => [
            'query_providers' => [
                'default' => 'default_orm',
                'fetch_all' => 'entity_name_fetch_all',
                // or fetch, update, patch, delete
            ],
        ],
    ],
],
```

### Register EntityName Query Create Filter

Source: https://github.com/laminas-api-tools/api-tools-doctrine/blob/2.5.x/README.md

This snippet shows how to register an EntityName query create filter within the Laminas Service Manager configuration. It specifies the class name for the filter and its factory.

```php
'entity_name' => \Application\Query\CreateFilter\EntityName::class,
    ],
    'factories' => [
        \Application\Query\CreateFilter\EntityName::class => \Laminas\ServiceManager\Factory\InvokableFactory::class,

### Configure Query Providers in api-tools-doctrine

Source: https://github.com/laminas-api-tools/api-tools-doctrine/blob/2.5.x/docs/UPGRADE-0.3.0.md

This snippet shows how to configure default and custom query providers within the api-tools-doctrine configuration. It specifies the mapping between query provider names and their respective implementations.

```php
'query_providers' => array(
    'default' => 'default_odm',
    'fetch_all' => 'Key.in.api-tools-doctrine-query-provider',
),
```

--------------------------------

### Attach Custom Event Listener in PHP

Source: https://github.com/laminas-api-tools/api-tools-doctrine/blob/2.5.x/README.md

Demonstrates how to attach a custom listener to a Doctrine resource event using the Shared Event Manager. This allows intercepting and modifying entity operations like creation.

```php
use Laminas\ApiTools\Doctrine\Server\Event\DoctrineResourceEvent;

$sharedEvents = $this->getApplication()->getEventManager()->getSharedManager();

$sharedEvents->attach(
    'Laminas\ApiTools\Doctrine\DoctrineResource',
    DoctrineResourceEvent::EVENT_CREATE_PRE,
    function(DoctrineResourceEvent $e) {
        $e->stopPropagation();
        return new ApiProblem(400, 'Stop API Creation');
    }
);
```

### Configure Entity Factory for Doctrine Entities

Source: https://github.com/laminas-api-tools/api-tools-doctrine/blob/2.5.x/README.md

This snippet illustrates how to specify a custom entity factory for Doctrine entities within the 'doctrine-connected' configuration. By setting 'entity_factory' to a key registered in the Service Manager, you can delegate entity instantiation, useful for entities with complex constructor requirements.

```php
'api-tools' => [
    'doctrine-connected' => [
        'Api\\V1\\Rest\\...Resource' => [
            'entity_factory' => 'key_in_service_manager',
            ...
        ],
    ],
],
```

```json
{
    "objectManager": "doctrine.entitymanager.orm_default",
    "serviceName": "Artist",
    "entityClass": "Db\\Entity\\Artist",
    "routeIdentifierName": "artist_id",

    "routeMatch": "/api/artist",
    "pageSizeParam": "limit",
    "hydratorName": "DbApi\\V1\\Rest\\Artist\\ArtistHydrator"
}
```

--------------------------------

### Doctrine Metadata API

Source: https://github.com/laminas-api-tools/api-tools-doctrine/blob/2.5.x/README.md

Retrieves metadata for Doctrine entities. You can query for a specific entity's metadata by providing its name, or retrieve all metadata for a given object manager by omitting the entity name.

```APIDOC
## GET /api-tools/api/doctrine[/:object_manager_alias]/metadata[/:name]

### Description

### Validate OAuth2 Client Scope and Inject User Identity

Source: https://github.com/laminas-api-tools/api-tools-doctrine/blob/2.5.x/docs/RELEASE-0.3.2.md

This PHP code defines a Query Create Filter for api-tools-doctrine. It validates if an authenticated OAuth2 client possesses the 'create' scope and injects the user's ID into the entity's data. It relies on LaminasApiToolsDoctrineServerQueryCreateFilterDefaultCreateFilter and requires an OAuth2 Server instance.

```php
namespace RollNApi\Query\CreateFilter;

use Laminas\ApiTools\Doctrine\Server\Query\CreateFilter\DefaultCreateFilter;
use Laminas\ServiceManager\ServiceLocatorAwareInterface;
use Laminas\ServiceManager\ServiceLocatorInterface;
use Laminas\ApiTools\ApiProblem\ApiProblem;
use Laminas\ApiTools\Rest\ResourceEvent;

class UserAlbumCreateFilter extends DefaultCreateFilter
{
    public function filter(ResourceEvent $event, $entityClass, $data)
    {
        $validate = $this->validateOAuth2('create');
        if ($validate instanceof ApiProblem) {
            return $validate;
        }

        $request = $event->getRequest()->getQuery()->toArray();

        $identity = $event->getIdentity()->getAuthenticationIdentity();
        $data->user = $identity['user_id'];

        return $data;
    }
}
```

This configuration snippet demonstrates how to set the 'entity_identifier_name' within the 'api-tools-rest' configuration. This allows specifying which field from the entity metadata should be used as the identifier when interacting with the API.

```php
'api-tools-rest' => array(
        'LaminasTestApiToolsDbApi\\V1\\Rest\\ArtistByName\\Controller' => array(
            'listener' => 'LaminasTestApiToolsDbApi\\V1\\Rest\\ArtistByName\\ArtistByNameResource',
            'route_name' => 'api-tools-test-api-tools-db-api.rest.doctrine.artist-by-name',
            'route_identifier_name' => 'artist_name',
            'entity_identifier_name' => 'name',
            'collection_name' => 'artist_by_name',
            'entity_http_methods' => array(
