This module provides the classes for integrating Doctrine with Apigility.
Installation of this module uses composer. For composer documentation, please refer to getcomposer.org.
$ php composer.phar require zfcampus/zf-apigility-doctrine
This library provides two modules. The first, ZF\Apigility\Doctrine\Server
provides
the classes to serve data created by the second, ZF\Apigility\Doctrine\Admin
. The
Admin module is used to create apigility resources and the Server serves those
created resoruces. Generally you would include Admin in your development.config.php
and Server in your application.config.php
/apigility/api/doctrine[/:object_manager_alias]/metadata[/:name]
This will return metadata for the named entity which is a member of the named object manager. Querying without a name will return all metadata for the object manager.
/apigility/api/module[/:name]/doctrine[/:controller_service_name]
This is a Doctrine resource route like Apigility Rest /apigility/api/module[/:name]/rest[/:controller_service_name]
To create a resource do not include [/:controller_service_name]
POST Parameters
{
"objectManager": "doctrine.entitymanager.orm_default",
"serviceName": "Artist",
"entityClass": "Db\\Entity\\Artist",
"routeIdentifierName": "artist_id",
"entityIdentifierName": "id",
"routeMatch": "/api/artist",
"pageSizeParam": "limit", // optional default null
"hydratorName": "DbApi\\V1\\Rest\\Artist\\ArtistHydrator", // Optional default generated
"hydrateByValue": true // Optional default true
}
By default the admin tool hydrates entities by reference by setting $config['doctrine-hydrator']['hydrator_class']['by_value']
to false.
It is possible to hook in on specific doctrine events of the type DoctrineResourceEvent
.
This way, it is possible to alter the doctrine entities or collections before or after a specific action is performed.
Supported events:
EVENT_FETCH_PRE = 'fetch.pre';
EVENT_FETCH_POST = 'fetch.post';
EVENT_FETCH_ALL_PRE = 'fetch-all.pre';
EVENT_FETCH_ALL_POST = 'fetch-all.post';
EVENT_CREATE_PRE = 'create.pre';
EVENT_CREATE_POST = 'create.post';
EVENT_UPDATE_PRE = 'update.pre';
EVENT_UPDATE_POST = 'update.post';
EVENT_PATCH_PRE = 'patch.pre';
EVENT_PATCH_POST = 'patch.post';
EVENT_PATCH_LIST_PRE = 'patch-all.pre';
EVENT_PATCH_LIST_POST = 'patch-all.post';
EVENT_DELETE_PRE = 'delete.pre';
EVENT_DELETE_POST = 'delete.post';
EVENT_DELETE_LIST_PRE = 'delete-list.pre';
EVENT_DELETE_LIST_POST = 'delete-list.post';
Attach to events through the Shared Event Manager:
use ZF\Apigility\Doctrine\Server\Event\DoctrineResourceEvent;
$sharedEvents = $this->getApplication()->getEventManager()->getSharedManager();
$sharedEvents->attach(
'ZF\Apigility\Doctrine\DoctrineResource',
DoctrineResourceEvent::EVENT_CREATE_PRE,
function(DoctrineResourceEvent $e) {
$e->stopPropagation();
return new ApiProblem(400, 'Stop API Creation');
}
);
It is also possible to add custom event listeners to the configuration of a single doctrine-connected resource:
'zf-apigility' => array(
'doctrine-connected' => array(
'Api\\V1\\Rest\\User\\UserResource' => array(
// ...
'listeners' => array(
'key.of.aggregate.listener.in.service_manager'
),
),
),
),
You may delimit multi keys through the route parameter. The default delimiter is a period . (e.g. 1.2.3). You may change the delimiter by setting the DoctrineResource::setMultiKeyDelimiter($value)
You may specify multiple route parameters and as long as the route matches then the route parameter names will be matched to the entity.
For instance, a route of /api/artist/:artist_id/album/:album_id
mapped to the Album
entity will filter the Album for field names. So, given an album with id, name, and artist
fields the album_id matches to the resoruce configuration and will be queried by key
and the artist is a field on album and will be queried by criteria so the final query
would be
$objectManager->getRepository('Album')->findOneBy(
'id' => :album_id,
'artist' => :artist_id
);
The album(_id) is not a field on the Album entity and will be ignored.
Query Providers are available for all find operations. The find query provider is used to fetch an entity before it is acted upon for all DoctrineResource methods except create.
A query provider returns a QueryBuilder object. By using a custom query provider you may inject conditions specific to the resource or user without modifying the resource. For instance, you may add a $queryBuilder->andWhere('user = ' . $event->getIdentity());
in your query provider before returning the QueryBuilder created therein. Other uses include soft deletes so the end user can only see the active records.
A custom plugin manager is available to register your own query providers. This can be done through this configuration:
'zf-apigility-doctrine-query-provider' => array(
'invokables' => array(
'entity_name_fetch_all' => 'Application\Query\Provider\EntityName\FetchAll',
)
),
When the query provider is registered attach it to the doctrine-connected resource configuration. The default query provider is used if no specific query provider is set. You may set query providers for these keys:
- default
- fetch
- fetch_all
- update
- patch
- delete
'zf-apigility' => array(
'doctrine-connected' => array(
'Api\\V1\\Rest\\....' => array(
'query_providers' => array(
'default' => 'default_orm',
'fetch_all' => 'entity_name_fetch_all',
// or fetch, update, patch, delete
),
),
),
),
In order to filter or change data sent to a create statement before it is used to hydrate the entity you may use a query create filter. Create filters are very similar to Query Providers in their implementation.
Create filters take the data as a parameter and return the data, modified or filtered.
A custom plugin manager is available to register your own create filters. This can be done through following configuration:
'zf-apigility-doctrine-query-create-filter' => array(
'invokables' => array(
'entity_name' => 'Application\Query\CreateFilter\EntityName',
)
),
Register your Query Create Filter as:
'zf-apigility' => array(
'doctrine-connected' => array(
'Api\\V1\\Rest\\....' => array(
'query_create_filter' => 'entity_name',
...
),
),
),
