您可以为Doctrine ODM设置默认ID策略吗？

Question

When setting up annotations with Doctrine ODM for the id field of a document you can specify a different key generation strategy that the default MongoId method like so:

/** @ODM\Document(collection="documents") */
class Document
{
    /**
    * @ODM\Id(strategy="UUID")
    */
    protected $id;
}

This requires you to specify this strategy for every new document mapping you set up. Is it possible to change the default strategy for your entire application? Maybe via a configuration option at the connection level?

Answer 1

Isn't the inheritance enough?

use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;

/** @ODM\Document */
abstract class AbstractDocument
{
   /**
   * @ODM\Id(strategy="UUID")
   */
   protected $id;

   public function getId()
   {
      return $this->id;
   }
}

/** @ODM\Document(collection="MyDocument") */
class MyDocument extends AbstractDocument {}

/** @ODM\Document(collection="AnotherDocument") */
class AnotherDocument extends AbstractDocument {}

then you can:

$myDocument = new MyDocument();
$odm->persist($myDocument);
$odm>flush();
$myDocument->getId();
