Tracking schema with associations

Hello,

I track schemas items, reservations, and items_reservations. I want to show all Item changes, including the item reservations, when any item_reservation is inserted or deleted.

I start the query from versions and searching for entity_schema is items, and entity_id is the current item id. After that I need to join all 'items_reservations' versions to know when item was reserved or deleted from reservation.
