rails-observers: Undefined method `cache_sweeper' or uninitialized constant ActionController::Caching::Sweeper
I use cache sweepers in my project and try to make it work on Rails 4 master. I have added gem 'rails-observers', updated bundle. But I am still getting error undefined methodcache_sweeper’ for ObservationsController:Class (NoMethodError)`.
I tried to debug and saw that rails-observers are actually loaded, but unfortunately I failed to go deeper into that eager_autoload stuff.
If I try to require my sweeper on top of controller I got error there: uninitialized constant ActionController::Caching::Sweeper. So it seems the values are not properly autoloaded
I tried both v 1.1.0 and edge version of the gem.

I fixed the error:
uninitialized constant ActionController::Caching::Sweeper (NameError)by addingrequire "rails/observers/action_controller/caching"at the top of the sweeper file.Using the gem from the master branch, I’m also still getting this error. Example: jb/rails-sweeper-error
As a work around, I’m using an observer instead, and expiring the cache with
ApplicationController.expire_page('/index.html'). But maybe I’m missing something?
