You want to delete the rest of sessions for that user, but in a
regular setup of the AR session store the user_id associated to a
record is marshalled as session data.
You''d need to add a custom column user_id in the sessions table and
maintain that column somehow, for example in an after_filter in
ApplicationController. This solution is explained in The Rails Way.
