Rails 3 - How can you get access to current_user in the IRB console?

I’m doing some design/debugging in IRB and need to login a user and then be able to gain access to current_user in my efforts (I’m using Devise for authentication.)

I found a sequence from SO that allows me to successfully login via IRB and access a page response:

>> ApplicationController.allow_forgery_protection = false
>> app.post('/sign_in', {"user"=>{"login"=>"some-login-id", "password"=>"some-password"}})
>> app.get '/some_other_path_that_only_works_if_logged_in'
>> pp app.response.body

I’ve been able to get session info:

>> app.session
 => {"_csrf_token"=>"1yAn0jI4VWzUH84PNTH0lVhjpY98e9echQGS4=", "session_id"=>"89984667d30d0fec71f2a5cbb9017e24"}

I’ve tried everything I can think of to try to get to current_user via app and app.session, but no luck. How can I access current_user?
