Why can't I use a session? (Symbol as array index)

Rails
1

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.

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.
