Symfony2 – Franz Jordán 2011
This metadata can be specified in a number of different formats including YAML, XML or directly
inside the Product class via annotations:
A bundle can accept only one metadata definition format. For example, it's not possible to mix
YAML metadata definitions with annotated PHP entity class definitions.
// src/Acme/StoreBundle/Entity/Product.php
namespace Acme\StoreBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity
* @ORM\Table(name="product")
*/
class Product
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string", length=100)
*/
protected $name;
/**
* @ORM\Column(type="decimal", scale=2)
*/
protected $price;
}
/**
* @ORM\Column(type="text")
*/
protected $description;
The table name is optional and if omitted, will be determined automatically based on the name
of the entity class.
Doctrine allows you to choose from a wide variety of different field types, each with their own
options. For information on the available field types, see the Doctrine Field Types
Reference section.
You can also check out Doctrine's Basic Mapping Documentation for all details about mapping
information. If you use annotations, you'll need to prepend all annotations
with ORM\ (e.g. ORM\Column(..)), which is not shown in Doctrine's documentation. You'll
also need to include the use Doctrine\ORM\Mapping asORM; statement,
which imports the ORM annotations prefix.
