Rails - Mar 2006 - Accessing cookie and session objects

Is it possible to directly access session and cookie objects from within 
a Model? When I try to read the session object in my User Model I get 
the following error:

NameError (undefined local variable or method `session'' for
User:Class):

I could pass attributes taken from the session into my method in the 
User Model, but this seems to go against DRY.

No, ActiveRecord models have no direct access to the ActionController
objects or methods. Handling sessions or cookies within the model would
breach against the MVC (Model, View, Controller) principle what is the
base Rails is build upon. It goes over DRY.

If you need some information about session parameters in the model, pass
them to model methods.

Yes, I suppose MVC should trump DRY. I''ll just send my session 
attributes to the Model.
