如何在Rails中编写增加日助手？

Question

我有下面的帮助,应该把日期放在单词取决于数字:

def day_in_words(number)
    case number
    when 0
      "Sunday"
    when 1
      "Monday"
    when 2
      "Tuesday"
    when 3
      "Wednesday"
    when 4
      "Thursday"
    when 5
      "Friday"
    when 6
      "Saturday"
    when 7
      "Sunday"
    when 8
      "Monday"
    when 9
      "Tuesday"
    when 10
      "Wednesday"
    when 11
      "Thursday"
    ...
    when 16
      "Sunday"
    when 17
      "Monday"
    when 18
      "Tuesday"
    when 19
      "Wednesday"
    when 20
      "Thursday"
    when 21
      "Friday"
    else
      "Unknown Day"
    end
  end
