module_prepend

🧩 Using Module#prepend for Method Overrides

Module#prepend lets you inject behavior before existing methods are invoked, making it excellent for decorators or logging. Unlike include, prepend places the module higher in the lookup chain. Use it to wrap or modify method behavior transparently.

module Auditor
  def save
    puts "Auditing before save"
    super
  end
end

class Record
  prepend Auditor

  def save
    puts "Saving record"
  end
end

Record.new.save
# ⇒ Auditing before save
# ⇒ Saving record
