Doctrine and Codeigniter: Entity not found - php

Question

I'm using Codeigniter 3 and Doctrine 2, which is loaded by a library class.
Doctrine itself is loaded via composer autoload.
On localhost (windows with php 5.6.0) I'm using the php built in server and everything is working.
When I'm uploading the project to my webserver (Plesk with nginx and proxied apache, php 5.6.15), i get the following error:
An uncaught Exception was encountered
Type: Doctrine\Common\Persistence\Mapping\MappingException
Message: Class 'Entity\User' does not exist

The controller is as follows:
....
public function show($id)
{
$user = $this->doctrine->em->getRepository('Entity\User')->findOneBy(array('id' => $id));
}
....
and the doctrine library:
use Doctrine\Common\ClassLoader,
Doctrine\ORM\Tools\Setup,
Doctrine\ORM\EntityManager;
class Doctrine {
public $em;
public function __construct()
{
// Load the database configuration from CodeIgniter
require APPPATH . 'config/database.php';
$connection_options = array(
'driver' => 'pdo_mysql',
'user' => $db['default']['username'],
'password' => $db['default']['password'],
'host' => $db['default']['hostname'],
'dbname' => $db['default']['database'],
'charset' => $db['default']['char_set'],
'driverOptions' => array(
'charset' => $db['default']['char_set'],
),
);
// With this configuration, your model files need to be in application/models/Entity
// e.g. Creating a new Entity\User loads the class from application/models/Entity/User.php
$models_namespace = 'Entity';
$models_path = APPPATH . 'models';
$proxies_dir = APPPATH . 'models/proxies';
$metadata_paths = array(APPPATH . 'models/entity');
// Set $dev_mode to TRUE to disable caching while you develop
$dev_mode = true;
// If you want to use a different metadata driver, change createAnnotationMetadataConfiguration
// to createXMLMetadataConfiguration or createYAMLMetadataConfiguration.
$config = Setup::createAnnotationMetadataConfiguration($metadata_paths, $dev_mode, $proxies_dir);
$this->em = EntityManager::create($connection_options, $config);
$loader = new ClassLoader($models_namespace, $models_path);
$loader->register();
}
}
The library is loaded via the autoload.php:
$autoload['libraries'] = array('OAuth2', 'session', 'doctrine');
the entity is located in models\Entity\
<?php
namespace Entity;
use Doctrine\ORM\Mapping\Entity;
defined('BASEPATH') OR exit('No direct script access allowed');
/**
* User Model
*
* #Entity
* #Table(name="user")
*/
class User {
/**
* #Id
* #Column(type="integer", nullable=false)
* #GeneratedValue(strategy="AUTO")
*/
protected $id;
....
The strange thing is that it works locally.
Any ideas?

Answer 1

Found the problem: Case-sensitivity of linux:
The folder of the entities should be capitalized according to the namespace. Since the directory was models\entity\ and Windows' file system is case-insensitiv, it worked on locally. But linux is case-sensitiv and expects models\Entity.
Renamed the folder to models\Entity and it's working.
