Find ActiveRecord Session by session_id

Searching Google has given me this:
<code>
@user=CGI::Session::ActiveRecordStore::Session.find_by_session_id(@session_ id).data[:user]</code>

That would have worked pre rails 2.3

which does not work either. It throws an error saying: NameError
(uninitialized constant CGI::Session::ActiveRecordStore):

I am probably guessing that is because CGI::Session::ActiveRecordStore
is a different class than ActionController::Session::AbstractStore which
my application uses.

The corresponding active record class is now
ActiveRecord::SessionStore::Session

Solved it, by using Raw SQL query to fetch the needed session object.
But decoding the base 64 encoded data gives some extra characters.
