activerecord-duplicator

https://github.com/kufu/activerecord-duplicator

activerecord-duplicator copies an ActiveRecord record and its associated rows (has_many, has_one, belongs_to, has_many :through) in one call. It rewires foreign keys through an internal id map, bypasses callbacks by using insert_all!, and lets you plug in per-model handlers for records that need custom logic. Composite primary keys (Rails 7.1+) are supported.
