如何从ActiveSupport :: Duration对象中恢复整数 [英] How to recover an integer from an ActiveSupport::Duration object

问题描述

如何恢复与ActiveSupport :: Duration对象相对应的整数？

How can I recover the integer corresponding to an ActiveSupport::Duration object?

同时可以恢复持续时间的类型吗？

At the same time, is it possible to recover the type of time duration?

例如：

foo = 2.day
bar = foo.duration_integer  # expected "2"
baz = foo.duration_type     # expected "day" or "days"

推荐答案

您可以使用 parts 访问器是这样的。第一个元素是您称为 duration_type 的元素，最后一个是整数值：

You can use the parts accessor like this. The first element is what you call the duration_type and the last one the integer value:

2.day.parts
=> [:days, 2]
