How to add attachements to custom entity

Hi, I created a custom bundle with a custom entity.

In my migrations I added AttachmentExtensionAwareInterface

/**
* {@inheritdoc}
*/
public function up(Schema $schema, QueryBag $queries)
{
$table = $schema->createTable('emuse_businesscard');
$table->addColumn('id', 'integer', ['autoincrement' => true]);
$table->addColumn('owner_id', 'integer', ['notnull' => false]);
$table->addColumn('createdAt', 'datetime', []);
$table->addColumn('updatedAt', 'datetime', ['notnull' => false]);
$table->setPrimaryKey(['id']);
$table->addIndex(['owner_id'], 'IDX_2F32390A7E3C61F9', []);
self::addUploadToBusinessCard($schema, $this->attachmentExtension);
}

/**
* @param Schema $schema
* @param AttachmentExtension $attachmentExtension
*/
public static function addUploadToBusinessCard(Schema $schema, AttachmentExtension $attachmentExtension)
{
$attachmentExtension->addImageRelation(
$schema,
'emuse_businesscard',
'businesscard_upload',
[],
2,
1024,
768
);
}

But when I run my migrations I get an error:

php app/console oro:migration:load --dry-run --show-queries

An extend field "businesscard_upload" cannot be added to non extend entity "eMuse\Bundle\BusinessCardBundle\Entity\BusinessCardEntity".


How can I make my entity extendable, or what is the best way to add an attachement ?

Hi, @neal_vanmeert.

To make your entity extenable, your entity should extends from empty class eMuse\Bundle\BusinessCardBundle\Model\ExtendBusinessCardEntity.
And another thing, your entity should be configurable (should have @Config annotation).

For example, please look how it was done for Account entity https://github.com/orocrm/crm/blob/master/src/OroCRM/Bundle/AccountBundle/Entity/Account.php.
Here, at line 28 we have Config annotation and at line 60 we have extends from empty OroCRM\Bundle\AccountBundle\Model\ExtendAccount class.

Hi, This indeed helped, I don’t really understand how an extend of an empty class makes this work. Is there info to be found ?

We are interested in OroCRM and creating modules for it, but we are lacking information to really create quality code.

Hi, @neal_vanmeert.
We have some documentation about extend entities here http://oroinc.com/orocrm/doc/current/book/entities
