Symfony2 – Franz Jordán 2011
To do this, add the name of the repository class to your mapping definition.
// src/Acme/StoreBundle/Entity/Product.php
namespace Acme\StoreBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity(repositoryClass="Acme\StoreBundle\Repository\ProductRepository")
*/
class Product
{
//...
}
Doctrine can generate the repository class for you by running the same command used earlier to
generate the missing getter and setter methods:
php app/console doctrine:generate:entities Acme
Next, add a new method - findAllOrderedByName() - to the newly generated repository
class. This method will query for all of the Product entities, ordered alphabetically.
// src/Acme/StoreBundle/Repository/ProductRepository.php
namespace Acme\StoreBundle\Repository;
use Doctrine\ORM\EntityRepository;
class ProductRepository extends EntityRepository
{
public function findAllOrderedByName()
{
return $this->getEntityManager()
->createQuery('SELECT p FROM AcmeStoreBundle:Product p ORDER BY p.name ASC')
->getResult();
}
}
The entity manager can be accessed via $this->getEntityManager() from inside the repository.
You can use this new method just like the default finder methods of the repository:
$em = $this->getDoctrine()->getEntityManager();
$products = $em->getRepository('AcmeStoreBundle:Product')
->findAllOrderedByName();
When using a custom repository class, you still have access to the default finder methods such
as find() and findAll().
Entity Relationships/Associations
Suppose that the products in your application all belong to exactly one "category". In this case,
you'll need a Category object and a way to relate a Product object to a Category object. Start
by creating the Category entity. Since you know that you'll eventually need to persist the class
through Doctrine, you can let Doctrine create the class for you.
