Question

I am trying to get data from a table with Doctrine 2 in a Symfony2 application. Code that works on my development machine throws an error when deployed to a production server. Here is one of my controllers.

public function listEntitiesAction($entity, Request $request)
{       
    $repository = $this->getDoctrine()->getRepository('AALCOInventoryBundle:' . $entity);
    $metadata = $this->getDoctrine()->getEntityManager()->getClassMetadata('AALCOInventoryBundle:' . $entity);
    $dataTable = new Datatable( $request->query->all(), $repository, $metadata, $this->getDoctrine()->getEntityManager());  
    $dataTable->makeSearch();   
    $view = $this->view($dataTable->getSearchResults(), 200)
            ->setFormat('json');
    return $this->get('fos_rest.view_handler')->handle($view);
}

The above code works on a linux server in my local development machine. One of the entities, is as follows.

<?php
namespace AALCO\InventoryBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
 * AALCO\InventoryBundle\Entity\Uom
 *
 * @ORM\Table(name="uoms")
 * @ORM\Entity
 */
class Uom
{
    // entity stuff
}

I have default settings for doctrine on config.yml and this is the error.

request: ErrorException: Warning: class_parents() [<a href='function.class-parents'>function.class-parents</a>]: Class AALCO\InventoryBundle\Entity\uom does not exist and could not be loaded in 
/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/RuntimeReflectionService.php line 40 (uncaught exception) at 
/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/RuntimeReflectionService.php line 40

Running php app/console doctrine:mapping:info returns OK for all the entities. I’ve checked other answers on SO for this type of error and none match my specific problem.

Symfony2 uses autoloading to load files with classes. When you ask for uow class it looks for uow.php file. File names are case sensitive on a linux server , so uow.php and Uow.php are different files.

You’ll need to add some sort of map or use ucfirst function on $entity.
