You can create some has_many :through associations to keep history of associations changes. Also you can track for changes in your object with Active Model Dirty: https://api.rubyonrails.org/classes/ActiveModel/Dirty.html

Or create separate table/tables for tracking all changes.

Or if you don't want to implement it all by yourself, you can use gem for this case: I think that is the most popular one:
