Reading back through I might still not have explained simply enough. I have a VehicleSearch Model with a m2m to Vehicle and a FK to User. I want to be able to notify the user that has the VehicleSearch object when a vehicle inside of the m2m has been added or updated.
I'm looking for the best way to cross reference the new ones and the best way to handle the notifications that the specific VehicleSearch was updated with N new vehicles and there were changes to N vehicles.
