是否有 Rails 助手或其他 Ruby 方法来获取 DateTime 对象并转换为类似的东西？

  • “13 天”（如果不到一个月）
  • “3 个月”（如果不到一年）
  • “1年3个月”

我熟悉 Rails内置的 helpers，但正在寻找能给我上面输出的东西。

也许distance_of_time_in_words是您正在寻找的：

distance_of_time_in_words(from_time, from_time + 50.minutes)        # => about 1 hour
distance_of_time_in_words(from_time, 50.minutes.from_now)           # => about 1 hour
distance_of_time_in_words(from_time, from_time + 15.seconds)        # => less than a minute
distance_of_time_in_words(from_time, from_time + 15.seconds, true)  # => less than 20 seconds
distance_of_time_in_words(from_time, 3.years.from_now)              # => about 3 years
distance_of_time_in_words(from_time, from_time + 60.hours)          # => 3 days
distance_of_time_in_words(from_time, from_time + 45.seconds, true)  # => less than a minute
distance_of_time_in_words(from_time, from_time - 45.seconds, true)  # => less than a minute
distance_of_time_in_words(from_time, 76.seconds.from_now)           # => 1 minute
distance_of_time_in_words(from_time, from_time + 1.year + 3.days)   # => about 1 year
distance_of_time_in_words(from_time, from_time + 3.years + 6.months) # => over 3 years
distance_of_time_in_words(from_time, from_time + 4.years + 9.days + 30.minutes + 5.seconds) # => about 4 years

Rails 辅助方法是您想要的，然后您使用 i18n 对其进行自定义。查看这些答案：Rails distance_of_time_in_words 返回“en，about_x_hours”

另外，看看这是如何实现的： https ://github.com/rails/rails/blob/master/actionpack/lib/action_view/helpers/date_helper.rb
