一个美国州的简称，全名（宝石国家和国家选择）答案

【问题标题】：The short name of a USA state by its full name (the gems countries and country_select)一个美国州的简称，全名（宝石国家和国家选择）
【发布时间】：2014-08-04 08:48:50
【问题描述】：

我在国家和他们的州（美国和加拿大）使用 2 颗宝石：

gem "countries"
gem "country_select"

为了简单起见，假设我只使用USA，并且我的状态为California。我想获得它的简称，即 CA。我可以通过迭代所有状态以非常直接的方式做到这一点。但这可能有标准方法。

那么它存在吗？如果没有，有简单的方法吗？

【解决方案1】：

迭代似乎是最简单的方法，因为 countries 将 State Select 作为 TODO。
