the proceed i've implemented have "deleted_at" timestamp buttress denote gets timestamped destroy slight called

def destroy
  @foo = foo.find(params[:id])
  @foo.update_attribute(:deleted_at, time.now)
  ...
end

to revert/undo i'll only set same buttress nil

def revert
  @foo = foo.find(params[:id])
