我所能提出的是关于同一个schnaader的想法： code> MONTHNAMES 等，然后循环遍历映射，执行 gsub 。那就是：

All I can come up with is about the same schnaader's idea: make a mapping between MONTHNAMES, etc. and then loop through the mapping, doing gsub. That is:

english_to_italian = {
  'english' => 'italian',
  ...
  'august' => 'agosto',
  ...
}

english_to_italian.each do |en, it|
  date_string.gsub!(/\b#{en}\b/i, it)
end

date = Date.parse(date_string)

Date.italy （与日期::意大利​​，我想）方法值得指出，以防万一有日历差异，我不知道。

The Date.italy (same as Date::ITALY, I think) method is worth pointing out, just in case there are calendar differences that I'm not aware of.

真的，我很惊讶，我找不到一个一般的解决方案。也许有一些可以做的Rails的i18n模块？

Really, I'm surprised I couldn't find a general solution for this. Maybe there are some i18n modules for Rails that might do it?
