Rails - Nov 2010 - Help: delegated association 'App' returning ActionDispatch::Integration::Session instead

class Foo < ActiveRecord::Base
  has_one :bar
  delegate :app, :to => :bar
end

class Bar < ActiveRecord::Base
  belongs_to :app

  def self.attribute_column_names
    return @@attr_columns if defined?(@@attr_columns)
    readers = content_columns.map { |n| n.name.intern } -
[:created_at,:updated_at]
    @@attr_columns ||= readers.map { |k| [k, "#{k}=".to_sym] }.flatten
  end
end


This all worked fine until in the console in my staging and production
environments, I assigned bar.app to an undefined variable:

Bar.all.each do |p|
  p.update_attribute("app_id", my_undefined_variable)
end

After doing this, I get:
  NameError: undefined local variable or method
`my_undefined_variable'' for main:Object

and
for whatever reason Foo.first.app is now returning an
ActionDispatch::Integration::Session object -- not only in the
console, but through the web, as well.

How can I correct this?

Update- I think the ActionDispatch::Integration::Session is only
returned in console.

Seems that console believes I''m calling it''s own
''app'' method even
though I''ve delegated it to an association.

Is this something worth filing a bug report on?  Should I just rename
App to something else, however unnatural it may be?
