Rails Trackable Concern: Automatically Set Created By

                  module Trackable
  extend ActiveSupport::Concern

  included do
    before_create :set_created_by
  end

  private

  def set_created_by
    self.created_by = Current.user
  end
end

                  class Post < ApplicationRecord
  include Trackable

  belongs_to :user, foreign_key: :created_by, optional: true
end

The Trackable concern automatically assigns the created_by field when a record is created, using Current.user. This keeps model logic clean while ensuring proper tracking of record ownership. The Post model includes Trackable, to get this functionality. A potential challenge is managing Current.user in background jobs. This approach makes user attribution seamless.
