Validation doesn't work using Symfony2.8 - symfony

Question

I am a newbie in using Symfony2.8 and I got a validation problem.
This is how my code from dependency injection looks like --
<?php
namespace AppBundle\DependencyInjection;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
class AppExtension extends Extension
{
public function load(array $configs, ContainerBuilder $container) {
$r = new \ReflectionClass(get_class($this));
$dir = dirname($r->getFileName());
$loader = new YamlFileLoader($container, new FileLocator($dir.'/../Resources/config'));
$loader->load('validation.yml');
}
}
And then I am trying to validate that those two columns are unique. (UniqueConstraint).
# src/AppBundle/Resources/config/validation.yml
AppBundle\Entity\StaticContent:
constraints:
- Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity:
fields: [build, name]
With StaticContent in the Entity and it complains that it can't find the StaticContent.
nebo#localhost:/var/www/html/iclei$ php app/console doctrine:schema:update --dump-sql
[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException]
There is no extension able to load the configuration for "AppBundle\Entity\StaticContent" (in /var/www/html/iclei/src/AppBundle/DependencyInjection/../Resources/config/validation.yml). Looked for nam
espace "AppBundle\Entity\StaticContent", found none
What am I doing wrong ?
Also I have inside the
app/config/config.yml
framework:
#esi: ~
#translator: { fallbacks: ['%locale%'] }
secret: '%secret%'
router:
resource: '%kernel.root_dir%/config/routing.yml'
strict_requirements: ~
form: ~
csrf_protection: ~
validation: { enabled: true, enable_annotations: true }
And this is the structure of the Bundle which we are building.
DIR/src/AppBundle/Resources/config/doctrine/StaticContent.orm.yml
DIR/src/AppBundle/DependencyInjection/AppExtension.php
This is my doctrine configuration:
# Doctrine Configuration
doctrine:
dbal:
driver: pdo_mysql
host: '%database_host%'
port: '%database_port%'
dbname: '%database_name%'
user: '%database_user%'
password: '%database_password%'
charset: UTF8
# if using pdo_sqlite as your database driver:
# 1. add the path in parameters.yml
# e.g. database_path: '%kernel.root_dir%/data/data.db3'
# 2. Uncomment database_path in parameters.yml.dist
# 3. Uncomment next line:
#path: '%database_path%'
orm:
entity_managers:
default:
mappings:
AppBundle: ~
auto_generate_proxy_classes: '%kernel.debug%'
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
On I13 request I add my entity.
<?php
namespace AppBundle\Entity;
/**
* StaticContent
*/
class StaticContent
{
/**
* #var int
*/
private $id;
/**
* #var int
*/
private $build;
/**
* #var string
*/
private $name;
/**
* #var string
*/
private $type;
/**
* #var string
*/
private $data;
With their getters and setters.
AppBundle\Entity\StaticContent:
type: entity
table: null
repositoryClass: AppBundle\Repository\StaticContentRepository
id:
id:
type: integer
id: true
generator:
strategy: AUTO
fields:
name:
type: string
length: 255
data:
type: blob
manyToOne:
build:
targetEntity: AppBundle\Entity\Build
inversedBy: staticContents
joinColumn:
name: build_id
referencedColumnName: id
lifecycleCallbacks: { }

Please try to enable bundle under doctrine configuration and tell is it works:
# Doctrine Configuration
doctrine:
dbal:
driver: pdo_mysql
host: '%database_host%'
port: '%database_port%'
dbname: '%database_name%'
user: '%database_user%'
password: '%database_password%'
charset: UTF8
orm:
auto_generate_proxy_classes: "%kernel.debug%"
entity_managers:
default:
auto_mapping: true
mappings:
YOURBundle: ~
Change AppExtension:
<?php
namespace AppBundle\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
class AppExtension extends Extension {
/**
* {#inheritdoc}
*/
public function load(array $configs, ContainerBuilder $container) {
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__ . '/../Resources/config'));
}
}
