Answer 1

An entity is a data model and should only hold data (and not have any dependencies on services). If you want to modify your model in case of a certain event (PrePersist in your case) you should look into making a Doctrine listener for that. You can inject the container when defining the listener:

services:
    my.listener:
        class: Acme\SearchBundle\Listener\YourListener
        arguments: [@your_service_dependency_or_the_container_here]
        tags:
            - { name: doctrine.event_listener, event: prePersist }
