Ruby / Rails：将日期时间转换为自然语言（例如2012年3月23日至“本周五”） [英] Ruby/Rails: Converting datetime to natural language (e.g. 3/23/2012 to "this Friday")

问题描述

有没有人知道一个gem，方法或代码片段，将datetime值转换为更人性化的时间，而无需创建一系列规则或在视图中放置一堆逻辑？例如：如果今天是2012年3月19日，转换为：

• 3/23/2012至本周五


• 3/26/2012至下周一


• 3/31/2012至下周末


• 4 / 15/2012至下个月


• 3/15/2012至上周四


• 3/01/2011至去年

基本上，我正在寻找与慢性宝石。更类似于 distance_of_time_in_words ，但有一个扭曲。而不是从数据库中获取日期并按原样显示，我希望使它们在显示给最终用户时更加人性化，更加友好。

解决方案

这是一个小小的黑客，完全没有完成和不合适。但是Ruby / Rails是非常棒的日期，范围是如此完美，也许如果你没有找到宝石，这样的事情会让你开始：

  module HumanDate 
 def date_difference_for_people（from，to）
 seconds_in_day = 24 * 60 * 60 
 days_difference =（（to  -  from）/ seconds_in_day）.round 
 case days_difference 
当-1 
昨天
当0 
今天
当1 
明天
当2..days_left_in_week 
this＃{day_name（difference）}
 when（days_left_in_week + 1）..（days_left_in_week + 7）
next week
 when（days_left_in_week + 8）.. days_left_in_month 
本月晚些时候
 else 
以后 - 剩下多少:-)
 end 
 end 
 
 def day_name（days_from_now）
 days_from_now.days_from_now.strftime（％A）
 end 
 
 def days_left_in_month 
时间。 now.end_of_month.day  -  Time.now.day 
 end 
 
 def days_left_in_week 
 Time.now.end_of_week.day  -  Time.now.day 
 end 
 end 
  

Is anyone aware of a gem, method, or code snippet that will convert datetime values into sometime more human-friendly without having to create a series of rules or put a bunch of logic in the view? For example: if today is 3/19/2012, convert:

• 3/23/2012 to "This Friday"
• 3/26/2012 to "Next Monday"
• 3/31/2012 to "Next weekend"
• 4/15/2012 to "Next month"
• 3/15/2012 to "Last Thursday"
• 3/01/2011 to "Last year"

Basically, I’m looking for the opposite of the Chronic gem. Something more similar to the distance_of_time_in_words, but with a twist. Instead of taking dates from the database and displaying them as-is, I’d like to make them more human-friendly and relatable when displayed to the end user.

解决方案

This is a little hack, totally unfinished and inelegant. But Ruby/Rails is so awesome with dates, and ranges are so perfect, maybe if you don't find the gem, something like this will get you started:

module HumanDate
  def date_difference_for_people (from, to)
    seconds_in_day = 24 * 60 * 60
    days_difference = ((to - from)/seconds_in_day).round
    case days_difference
      when -1
        "yesterday"
      when 0
        "today"
      when 1
        "tomorrow"
      when 2..days_left_in_week
        "this #{day_name(difference)}"
      when (days_left_in_week + 1)..(days_left_in_week + 7)
        "next week"
      when (days_left_in_week + 8)..days_left_in_month
        "later this month"
      else
        "later -- how much left to you :-)"
    end
  end

  def day_name(days_from_now)
    days_from_now.days_from_now.strftime("%A")
  end

  def days_left_in_month
    Time.now.end_of_month.day - Time.now.day
  end

  def days_left_in_week
    Time.now.end_of_week.day - Time.now.day
  end
end
