    At least on my system (rails 3.2, devise 2.0.4), you can do it like this:

    session is:

    {"session_id"=>"be02f27d504672bab3408a0ccf5c1db5", "_csrf_token"=>"DKaCNX3/DMloaCHbVSNq33NJjYIg51X0z/p2T1VRzfY=", "warden.user.user.key"=>["User", [3], "$2a$10$5HFWNuz5p6fT3Z4ZvJfQq."]}

    session["warden.user.user.key"][1][0], then is 3.

    So, I’d find it as:

    User.find(session["warden.user.user.key"][1][0])
