将数字年份转换为字符串

Question

Ruby中是否有内置方法将数字Year转换为字符串表示？
示例："2015" =＆gt; "twentyfifteen"

我知道我可以这样做：

def numeric_year_to_string(numeric_year)  
  years = {"2015" => "twentyfifteen", "2014" => "twentyfourteen" }
  years.has_key?(numeric_year) ? years[numeric_year] : "twentyfifteen"  
end  

Answer 1

Ruby中没有宝石或扩展程序可以执行此操作 - 您必须自己编写一个。

Humanize最接近 - https://github.com/radar/humanize

require 'humanize'

要求＆＃39;人性化＆＃39;

def numeric_year_to_string(numeric_year)
  tens = numeric_year%100
  hundreds = (numeric_year - tens) / 100
  return hundreds.humanize + " oh-" + tens.humanize if tens < 10
  hundreds.humanize + " " + tens.humanize
end

试试这个 - 它适用于大多数情况
