  • ОК ли е да ползвам method_missing за тази цел? Аргументацията ми е, че няма нужда да пипам нищо из Validations щом добавя нов шаблон, пък и избягвам досадни повторения.
  • ОК ли е да вкарам логиката с показване на част от потребителското име в шаблона? Струва ми се доста кофти, но пък не правя разни конкатенации в самия метод. От друга страна, би следвало тази логика да е точно в метода, а не в шаблона.
  • Това ли е правилният начин да сливам шаблони (ред 12 и 13)?
