Using a custom storage layer
Using a custom storage layer¶
FOSUserBundle has been designed to allow you to easily change the storage layer used by your application and keep all of the functionality provided by the bundle.
Implementing a new storage layer requires providing two classes: the user implementation and the corresponding user manager (you will of course need two other classes if you want to use the groups).
The user implementation must implement
and the user manager must implement
FOS\UserBundle\Model namespace provides base classes to make it easier to
implement these interfaces.
You need to take care to always call
before saving a user. This is done when calling
updateUser so you will
be safe if you always use the user manager to save the users.
If your storage layer gives you a hook in its saving process, you can use
it to make your implementation more flexible (this is done for Doctrine
using listeners for instance)
Configuring FOSUserBundle to use your implementation¶
To use your own implementation, create a service for your user manager. The
following example will assume that its id is
1 2 3 4 5 6 7
# app/config/config.yml fos_user: db_driver: custom # custom means that none of the built-in implementation is used user_class: AppBundle\Model\CustomUser service: user_manager: app.custom_user_manager firewall_name: main
Your own service can be a private one. FOSUserBundle will create an alias
to make it available through
The validation of the uniqueness of the username and email fields is done using the constraints provided by DoctrineBundle. You will need to take care of this validation when using a custom storage layer, using a custom constraint
