Not sure about existing gems, not having looked at this in Ruby or
Rails, but having solved it in another language: you create an entry in
your database with a token and a timestamp. When a user sends the token
back, you check the current time against the token's associated
timestamp, and reject it if the token is unknown or the timestamp is too
old. (Periodically, you can garden your database to delete any entry
with an old timestamp.)
