How to recover an integer from an ActiveSupport::Duration object

问题

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

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

exemple:

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

回答1:

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]
