alias_method_chain_emulation

📦 Emulating alias_method_chain safely

Create method chains by aliasing the original implementation and redefining the method, then invoking the aliased version. This pattern is explicit and avoids monkey‑patch pitfalls.

module Auditable
  def self.included(base)
    base.class_eval do
      alias_method :save_without_audit, :save

      def save(*args)
        audit_changes
        save_without_audit(*args)
      end
    end
  end
end

class Model
  include Auditable

  def save
    # persistence logic
  end
end
