I''ve created a module to include in a Controller. Basically it works,
but I am expecting methods in the module to have access to instance
variables from the controller, and that appears to not be the case.
Yet, a simple Ruby example says it should be. I''m not sure
what''s
different.
Simple Example:
module ShapeStuff
def set_type
@type = ''circle''
end
end
class Shape
include ShapeStuff
attr_accessor :type
def initialize
@type = ''square''
end
end
x = Shape.new
puts x.type # ''square''
x.set_type
puts x.type # ''circle''
My distilled Rails example would be something like this. I require
the file in environment.rb.
module EventControls
def change_test_var
@test_var = ''y''
end
end
class UsersAdminController < ApplicationController
include EventControls
layout ''1col_admin''
attr_accessor :test_var
def some_action
@test_var = ''x''
change_test_var
end
end
Using debug(@test_var) the value doesn''t ever appear to change from
''x''
Additionally, I expected session to be available to the module
methods too, but it isn''t.
Confused...

I just needed a sanity check that this should work before I start tearing it down section by section (at this point it''s quite a bit of code).
