如何评估年、月和日的日期差异(ruby)?

I have to make a simple difference between two dates:

我必须在两个日期之间做一个简单的区别:

Date.parse("2009-06-20") - Date.today

This gives me the difference of the dates in days.

这让我知道了日期的不同。

Anyone know a way to easily convert that to the following format:

任何人都知道一种简单地将其转换为以下格式的方法:

The event occurred X years, Y months and Z days ago

Thank you.

There is a RubyGem which returns Time difference in a hash like {:year => 0, :month => 0,...}

有一个RubyGem，它在一个散列中返回时差，比如{:year =>，:month => 0，…}

This is an example for difference in days, hours, seconds. Add the fields that you need.

这是天数、小时、秒的差异的一个例子。添加所需的字段。

def calculate_difference
  minutes = (Date.parse("2009-06-20") - Date.today).to_i / 60
  days = minutes / (24*60)
  minutes -= days * 24*60
  hours = minutes / 60
  minutes -= hours * 60
  "#{days}d#{hours}h#{minutes}m"
end

I don't know of any standard, correct way to do this. As odd as it may seem the standard Ruby library has a Date class but no DateSpan functionality. Rails has a solution but it feels somewhat of a pain for me to require this whole mammoth for such a trivial task.

我不知道有什么标准，正确的方法。奇怪的是，标准Ruby库有一个Date类，但是没有DateSpan功能。Rails有一个解决方案，但对于我来说，需要这整个庞然大物来完成这样一项琐碎的任务，感觉有点痛苦。
