checking ttl for Rails.cache object

问题

So I have some items stored in Rails.cache and I always write them with :expires_in => 5.minutes

My question is, is there a way to see what the ttl is on a cache entry?

I know the entry class in activesupport has a method but I can't seem to get an entry object out of Rails.cache methods.

I'm implementing rate limiting by the way.

You can check ttl in Rails cache using command below.

Rails.cache.data.ttl("yourkey")
