You would do that in your controller, or if you want to encapsulate the
functionality to be reusable, you can do it in the model. And you
already figured out the code for it!
Consider the following controller action
def add_film_to_actor
@actor = Actor.find(params[:actor_id])
@actor.films << Film.find(params[:film_id])
@actor.save
end
