What is the shortest way in ruby to write these four instructions?
u = User.email_equals("tabaluga@gmail.com").first
s = u.setting
s.regular_info = false
s.save

User.email_equals("tabaluga@gmail.com").first.setting.update_attribute(:regular_info, false)

User.find_by_email("tabaluga@gmail.com").setting.update_attribute(:regular_info, false)
