Rails - Jun 2006 - Why can''t I use a session? (Symbol as array index)

Hi All

I can''t for the life of me see what is wrong with this. Maybe
it''s cause
it''s midnight...

I want to put some data in a session and I have some code like this:

class ApplicationController < ActionController::Base

  model :mything

  def ApplicationController.chosen_thing

    session[:chosen_thing] ||= MyThing.defaultThing

  end

end

So whenever I try to access ApplicationController.mything in one of the 
controller subclasses I get the error below.

Any help much appreciated.

Donald

your method is _static_
but
session is an instance-bound method

change this

 def ApplicationController.chosen_thing

to

  def chosen_thing

Hi Donald,

You should not be using ApplicationController as either a controller name or 
as a method name.
