Ruby on Rails - set attribute after record was created

I'm using activeadmin in my RoR webapp. when I create a new user/record, I want to set/update an attribute depend on it's id/pk. e.g his id is 1234, column X should have the value 1234-XXX.

Since there is no activerecord callback for that(i cant set the value with callbacks, because there isnt one, after the entry is created/stored in the db) you to ask, how I could solve this?

Thanks in advance

I think you can use after_commit callback

after_commit :do_something, on: :create

def do_something
  update_column(:column_x, "#{id}-XXX")
end

You can use the after_action controller callback :

class RecordsController < ApplicationController
  after_action :set_columnx, only: [:create, :update]

  private
  def set_columnx
    @record = Record.find(params[:id])
    @record.columnx = "#{@record.id}-ABCD"
    @record.save!
  end
end
