Symfony2.1 mapping error: class_parents() - php

Question

I have a problem trying to get data from a table (via entity) using Doctrine2 in a Symfony2.1 project. Here is the controller where I get the error:
/**
* Country list
*/
public function countrylistAction()
{
$em = $this->getDoctrine()->getManager();
$countryList = $em->getRepository('ProjectBaseBundle:SYS_TCountry')
->findAll();
$serializer = new Serializer(array(new GetSetMethodNormalizer()),
array('json' => new JsonEncoder()));
return new Response($serializer->serialize($countryList, 'json'));
}
The entity:
<?php
namespace Company\Project\BaseBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity
* #ORM\Table(name="SYS_TCountry")
*/
class SYS_TCountry
{
/**
* #ORM\Id
* #ORM\Column(type="string", length=3, nullable=false)
* #var string
*/
protected $idcountry;
/**
* #ORM\Column(type="string", length=75, nullable=false)
* #Assert\NotBlank()
* #var string
*/
protected $name;
....
public function getIdcountry() { return $this->idcountry; }
public function getName() { return $this->name; }
public function getA2() { return $this->a2; }
public function getA3() { return $this->a3; }
public function getIdstatus() { return $this->idstatus; }
public function setIdcountry($idcountry) { $this->idcountry = $idcountry; }
public function setName($name) { $this->name = $name; }
public function setA2($a2) { $this->a2 = $a2; }
public function setA3($a3) { $this->a3 = $a3; }
public function setIdstatus($idstatus) { $this->idstatus = $idstatus; }
public function __toString() { return $this->idcountry; }
}
Config.yml:
# Doctrine Configuration
doctrine:
dbal:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: %database_name%
user: %database_user%
password: %database_password%
charset: UTF8
orm:
auto_generate_proxy_classes: %kernel.debug%
auto_mapping: true
And this is the error:
Warning: class_parents():
Class Company\Project\BaseBundle\Entity\SYS_TCountry does not exist and could not be loaded in
/var/www/project/src/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/RuntimeReflectionService.php line 40
It is strange because, as Doctrine says in console, the mapping is properly done: I test it executing php app/console doctrine:mapping:info:
[OK] Company\Project\BaseBundle\Entity\SYS_TCountry
and if I execute a query in console everything goes fine -> app/console doctrine:query:sql 'SELECT * FROM SYS_TCountry', that return results.
I do not know if using Symfony2.1 I have to configure something different to the 2.0 version, but seems the same because the mapping is Doctrine responsibility.

Answer 1

Symfony follows the PSR-0 standard for filenames. That, amongst other things, means that if you use an underscore in your class name, it will replace it with a directory separator when deciding where your class should live, like this:
\namespace\package\Class_Name => /path/to/project/lib/vendor/namespace/package/Class/Name.php
So, if you have a class named SYS_TCountry it would expect to find it in
Company/Project/BaseBundle/Entity/SYS/TCountry.php
instead of
Company/Project/BaseBundle/Entity/SYS_TCountry.php
I think that your best solution would be to change the filename and class name to SYSTCountry. You don´t need to change the table name.

Answer 2

Your class entity name is not compliant with PSR-0 which causes the loading error.
If you rename your entity to SYSTCountry everything will work fine!
Edit: Default Symfony2 and Doctrine autoloaders ARE PSR-0 compliant.
