I have a number of seconds. Let's say 270921. How can I display that number saying it is xx days, yy hours, zz minutes, ww seconds?

推荐答案

使用 divmod 可以非常简洁地完成:

It can be done pretty concisely using divmod:

t = 270921
mm, ss = t.divmod(60)            #=> [4515, 21]
hh, mm = mm.divmod(60)           #=> [75, 15]
dd, hh = hh.divmod(24)           #=> [3, 3]
puts "%d days, %d hours, %d minutes and %d seconds" % [dd, hh, mm, ss]
#=> 3 days, 3 hours, 15 minutes and 21 seconds

您可能可以通过使用 collect 或 inject 发挥创意来进一步干燥它，但是当核心逻辑是三行时，它可能会过大.

You could probably DRY it further by getting creative with collect, or maybe inject, but when the core logic is three lines it may be overkill.
