Hi,  I have a module in the /myApp/lib directory to help manage image
files.  It is coincidentally called 'image_manager'.

There is a function in there called asset_path, which is used to
determine the path of the images that is defined as follows:
  def asset_path
    "#{RAILS_ROOT}/#{ASSET_DIR}/#{foo.id}"
  end

I am including the image manager module in the model for the image, but
when I call this function I get the following error:
undefined local variable or method `foo' for #<Album:0x39b0d70>

"foo" is a function I have in my application controller and helper, and
is defined as follows:
  def foo
    session[:foo]
  end

Apparently the module can't see the methods in the application
controller and helper.  Is there some other way the module in 'lib' can
get at the object I have in my session?
