Subject: Model object in session problems

Hi,

I'm having a problem storing an AR model object in a session. Actually the problem doesn't seem to be related to storing 
it in a session. The problem occurs when the session is deserialised on the next request.

When the user logs in I pop a User object (an AR model) into the session and redirect to the homepage. Then I see the 
following error

<ActionController::SessionRestoreError: Session contained objects where the class definition wasn't available. Remember 
to require classes for all objects kept in the session. The session has been deleted. (Original exception: undefined 
class/module User [ArgumentError])>

Can anyone shed any light on my problem?


Thanks,

R.
