More about Doctrine implementations

FOSUserBundle was first written for Doctrine-based storage layers. This chapter describes some things specific to these implementations.

Using a different object manager than the default one

Using the default configuration , FOSUserBundle will use the default doctrine object manager. If you are using multiple ones and want to handle your users with a non-default one, you can change the object manager used in the configuration by giving its name to FOSUserBundle.

# app/config/config.yml
    db_driver: orm
    model_manager_name: non_default # the name of your entity manager


Using the default object manager is done by setting the configuration option to null which is the default value.

Replacing the mapping of the bundle

None of the Doctrine projects currently allow overwriting part of the mapping of a mapped superclass in the child entity.

If you need to change the mapping (for instance to adapt the field names to a legacy database), one solution could be to write the whole mapping again without inheriting the mapping from the mapped superclass. In such case, your entity should extend directly from FOS\UserBundle\Model\User (and FOS\UserBundle\Model\Group for the group). Another solution can be through doctrine attribute and relations overrides.


It is highly recommended to map all fields used by the bundle (see the mapping files of the bundle in Resources/config/doctrine/). Omitting them can lead to unexpected behaviors and should be done carefully.
