ActionController::Caching::Sweeper not autoloading

Rails
1

Hi

I’ve been following this issue on Lighthouse (https://
rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/1977-
actioncontrollercachingsweeper-autoloading-is-broken). I’ve since
upgraded to 2-3-stable which contain’s Josh’s fix, but I’m still
seeing the same error:

     `load_missing_constant': uninitialized constant

ActionController::Caching::Sweeper (NameError)

I’ve tried a variety of fixes as suggested in the Lighthouse comments,
all to no avail. The only way I can get my app to start is by
replacing:

@@@
class MySweeper < ActionController::Caching::Sweeper
@@@

with

@@@
require ‘rails/actionpack/lib/action_controller/caching/sweeper’
class MySweeper < ActionController::Caching::Sweeping::Sweeper
@@@

This is clearly wrong.

Can anyone help?

My environment.rb file is as follows, if this helps?

Rails::Initializer.run do |config|
  %w(sweepers observers accounting).each do |dir|
    config.load_paths << "#{RAILS_ROOT}/app/#{dir}"
  end
  config.cache_store = :file_store, "#{RAILS_ROOT}/tmp/cache"
  config.active_record.observers = :my_sweeper
  config.active_record.default_timezone = :utc
  config.action_controller.session_store = :active_record_store
  config.action_mailer.default_charset = "utf-8"
end
