Symfony2 production environment: Mapping exception due to custom User class not found in chain configuration-Collection of common programming errors

I’m developing a bit complex Symfony2.1 based app, with connection to two different databases (with two entity managers, one connected to Oracle and the other one to PostgreSQL) and a custom User class (with a custom password encoder).

I’ve managed to have it running correctly in dev environment, but whenever I try to run it in production environment I’m getting the next error:

Doctrine\Common\Persistence\Mapping\MappingException: The class ‘MyFirm\UserManagerBundle\Entity\User’ was not found in the chain configured namespaces (uncaught exception)

My security and encoders in app/config/security.yml:

security:
  encoders:
    MyFirm\UserManagerBundle\Entity\User:
        id: myfirm_usermanager.password_encoder

  providers:
    user_db:
        entity: 
            class: MyFirm\UserManagerBundle\Entity\User
            property: username

The doctrine.orm section in app/config/config.yml:

doctrine:
  orm:
    auto_generate_proxy_classes: %kernel.debug%
    default_entity_manager: user_config_db 
    entity_managers:
        event_db:
            connection:   event_db
            mappings:
                MyFirmEventManagerBundle: ~
        user_config_db:
            connection:   user_config_db
            mappings:
                MyFirmUserManagerBundle:  ~

And finally, this is the final Exception log:

Has somebody any clue? Thanks a lot.

  1. The problem seems it is a bug in Symfony2: the default entity manager must be named “default” if you want it to work in Production environment as the default entity manager.

    After changing the doctrine.orm section in app/config/config.yml to:

    doctrine:
  orm:
    auto_generate_proxy_classes: %kernel.debug%
    default_entity_manager: default
    entity_managers:
      event_db:
        connection:   event_db
        mappings:
            MyFirmEventManagerBundle: ~
      default:
        connection:   user_config_db
        mappings:
            MyFirmUserManagerBundle:  ~

    everything works.
