ruby-on-rails - How to determine the difference in dates in ruby

Question

I have some problem with comparing dates. I need to compare more than DateTime.now or record.updated_at for 7 days. I try do something like that: DateTime.now - record.updated_at but have result as that 143587.77856945992 or (14358777856939/8640000000000). I dont understand what is that. Maybee need convert to Time format or something else? Thanks

Answer 1

如果你想要的话，那么你可以使用 distance_of_time_in_words

Answer 2

利用：

((DateTime.now - record.updated_at) * 24 * 60 * 60).to_i

获取秒数

(DateTime.now - record.updated_at).to_i

获得天数（显然......）
