Is this unless block really needed? n.attribute?

ThugNotes PUT block Edit

# Are the 'n.attribute' and 'unless' blocks really needed here? 

put '/:id' do
  n = Note.get params[:id]
      n.content = params[:content]
      n.complete = params[:complete] ? 1 : 0
      n.updated_at = Time.now 
  if n.save
    redirect '/', :notice => "Note updated thuggishly."
  else
    redirect '/', :error => 'Update failed, son.'
  end
end

ThugNotes PUT block original
