PHP AppKernel Symfony Issue - php

Question

Note People have marked this question as simmilar to others, but its not =- I am not using symfony and doctrine as a web framework, I am using symfony components with doctrine while using Slimphp as the actual web framework.
So while you might think I need an AppKernel I don't. I am using symfony components. The only issue here is that #UniqueEntity isn't working.
I have no idea what I am doing. I am getting the error:
Fatal error: Class 'doctrine.orm.validator.unique' not found in /var/www/html/image_upload_app/vendor/symfony/validator/ConstraintValidatorFactory.php on line 46
My AppKernel.php looks like:
namespace ImageUploader;
use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;
class AppKernel extends Kernel {
public function registerBundles() {
$bundles = array(
new \Doctrine\Bundle\DoctrineBundle\DoctrineBundle()
);
return $bundles;
}
public function registerContainerConfiguration(LoaderInterface $loader) {}
}
From there I created a bootstrap.php with the following contents:
/** ---------------------------------------------------------------- **/
// Lets Setup Doctrine.
/** ---------------------------------------------------------------- **/
require_once 'vendor/autoload.php';
$loader = require 'vendor/autoload.php';
\Doctrine\Common\Annotations\AnnotationRegistry::registerLoader(array($loader, 'loadClass'));
use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;
/**
* Set up Doctrine.
*/
class DoctrineSetup {
/**
* #var array $paths - where the entities live.
*/
protected $paths = array(APP_MODELS);
/**
* #var bool $isDevMode - Are we considered "in development."
*/
protected $isDevMode = false;
/**
* #var array $dbParams - The database paramters.
*/
protected $dbParams = null;
/**
* Constructor to set some core values.
*/
public function __construct(){
if (!file_exists('db_config.ini')) {
throw new \Exception(
'Missing db_config.ini. You can create this from the db_config_sample.ini'
);
}
$this->dbParams = array(
'driver' => 'pdo_mysql',
'user' => parse_ini_file('db_config.ini')['DB_USER'],
'password' => parse_ini_file('db_config.ini')['DB_PASSWORD'],
'dbname' => parse_ini_file('db_config.ini')['DB_NAME']
);
}
/**
* Get the entity manager for use through out the app.
*
* #return EntityManager
*/
public function getEntityManager() {
$config = Setup::createAnnotationMetadataConfiguration($this->paths, $this->isDevMode, null, null, false);
return EntityManager::create($this->dbParams, $config);
}
}
/**
* Function that can be called through out the app.
*
* #return EntityManager
*/
function getEntityManager() {
$ds = new DoctrineSetup();
return $ds->getEntityManager();
}
/**
* Function that returns the conection to the database.
*/
function getConnection() {
$ds = new DoctrineSetup();
return $ds->getEntityManager()->getConnection();
}
use \ImageUploader\AppKernel;
$kernel = new AppKernel();
$kernel->loadClassCache();
I am unsure why I keep getting this error, I have a model (entity) that looks as such:
namespace ImageUploader\Models;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
/**
* #ORM\Entity
* #ORM\Table(name="users")
* #UniqueEntity(fields="userName")
* #UniqueEntity(fields="email")
*/
class User {
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue
*/
protected $id;
/**
* #ORM\Column(type="string", length=32, nullable=false)
* #Assert\NotBlank()
*/
protected $firstName;
/**
* #ORM\Column(type="string", length=32, nullable=false)
* #Assert\NotBlank()
*/
protected $lastName;
/**
* #ORM\Column(type="string", length=100, unique=true, nullable=false)
* #Assert\NotBlank(
* message = "Username cannot be blank"
* )
*/
protected $userName;
/**
* #ORM\Column(type="string", length=100, unique=true, nullable=false)
* #Assert\NotBlank()
* #Assert\Email(
* message = "The email you entered is invalid.",
* checkMX = true
* )
*/
protected $email;
/**
* #ORM\Column(type="string", length=500, nullable=false)
* #Assert\NotBlank(
* message = "The password field cannot be empty."
* )
*/
protected $password;
/**
* #ORM\Column(type="datetime", nullable=true)
*/
protected $created_at;
/**
* #ORM\Column(type="datetime", nullable=true)
*/
protected $updated_at;
}
when I go to validate the model, I get the error listed above. I have installed doctrine bundle and I thought I set things up properly. But apparently not. Does any know know what I am doing wrong? Did I configure something wrong or not configure something at all?

Answer 1

You don't need to use the appkernel, I misunderstood your problem in your other question.
The problem is that you are using the UniqueValidator from the bridge. This is designed to work with the full-stack framework, not for standalone usage (only components are standalone).
This means you cannot use this constraint. Instead, you can use a pure Doctrine solution: #UniqueConstraint.
