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 = { |n| } - [:created_at,:updated_at]     @@attr_columns ||= { |k| [k, "#{k}=".to_sym] }.flatten   end end

This all worked fine until in the console in my staging and production environments, I assigned 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 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?
