How can the Entity Manager be accessed using the pre_deserialize event in jms_serializer?

Question

symfony

Good afternoon. When the project object is deserialized, a responsible_id comes from the client, which should be transformed into the User entity. Those. as I understand it, I need to find the corresponding user in the pre_deserialize event and assign it to the future object. I can’t get this user yet, because I don’t know how to get access to the entity manager

Answer 1

Maybe it's worth using the method of a separate service as a licenser ? And entity manager to inject into it through the container?
