ruby-on-rails - 如何检查 Rails 中某个范围内是否包含日期时间？

Question

使用 Ruby 的 Range#include?具有日期时间范围会引发异常:

> (Time.zone.now.beginning_of_day..Time.zone.now.end_of_day).include?(Time.zone.now)
TypeError: can't iterate from ActiveSupport::TimeWithZone

在使用 Rails 时 Range#overlaps?作品:

> (Time.zone.now.beginning_of_day..Time.zone.now.end_of_day).overlaps?(Time.zone.now..Time.zone.now)
=> true

我不喜欢这样一个事实，即我必须创建一个单元素范围以使用 overlaps? 检查是否包含 有没有一种方法可以将 include? 与日期时间范围一起使用在 Rails 中？

Answer 1

啊哈!

这是怎么回事？

Time.zone.now.between?(Time.zone.now.beginning_of_day,Time.zone.now.end_of_day)

结果:

2.3.0 :001 > Time.zone.now.between?(Time.zone.now.beginning_of_day,Time.zone.tomorrow.end_of_day)
 => true 
2.3.0 :002 > Time.zone.tomorrow.between?(Time.zone.now.beginning_of_day,Time.zone.now.end_of_day)
 => false 
2.3.0 :003 > Time.zone.yesterday.between?(Time.zone.now.beginning_of_day,Time.zone.now.end_of_day)
