def id_attachment_require_upload?     !object.id_attachment? end  ...  def work_attachment_require_upload?     !object.work_attachment? end

i want make below.

array = %w(id address work) array.each |a|     def #{a}_attachment_require_upload?         !object.#{a}_attachment?     end end

is there way me create array of methods automatically in rails save me redundant work.

arup's answer looks it's way go i'm not sure if object.#{a}_attachment? work. if does, learned new today. can use public_send.

array = %w[id address work] array.each |a|   define_method "#{a}_attachment_require_upload?"     !object.public_send("#{a}_attachment?")   end end
