  • Можеш да интерполираш регулярни изрази в регулярни изрази
  • Ползвай константи за тези регулярни изрази, а не методи
  • Validations_regexps е супер невалидно име на константа :) ValidationsRegexps е най-малкото подобрение, което можеш да направиш с него :)
  • В кода ти като че ли има малко повторения, които биха могли да се избегнат

Сега кодът ти е по-добре.

Аз бих го написал така, ако искам да ползвам метапрограмиране, тъй като не очаквам отвън някой да вика Validations.validations:

[:email, :phone, :hostname, :ip_address, :number, :integer, :date, :time, :date_time].each do |validation_method|
  define_singleton_method("#{validation_method}?") do |value|
     test(/^#{const_get(validation_method.upcase)}$/, value)
  end
end

И в моето решение на тази задача, умишлено не съм използвал метапрограмиране, защото не сме говорили за него, но знам, че човек има нужда да си начеше крастата от време на време... :)
