Uninitialized constant ActionController::Caching::Fragments


#1

Hey, i’m trying to use “s3cache” plugin with my app, but after adding it
to my vendor/plugins directory and following the install steps i’m
getting this error after running script/server:

/Users/richardschneeman/Documents/AptanaStudio/slangasaurus/vendor/rails/activesupport/lib/active_support/dependencies.rb:275:in
load_missing_constant': uninitialized constant ActionController::Caching::Fragments::UnthreadedFileStore (NameError) from /Users/richardschneeman/Documents/AptanaStudio/slangasaurus/vendor/rails/activesupport/lib/active_support/dependencies.rb:467:inconst_missing’

I’ve extensively googled this error but haven’t been able to come up
with any good answers for what is causing it. Rails 2.1.0, Ruby 1.8.6:
this is the first two lines in s3_cache.rb:

require ‘s3’
class S3Cache <
ActionController::Caching::Fragments::UnthreadedFileStore

Any clues or suggestions??

Your plugin was written against 2.0.2. That class doesn’t exist in
rails 2.1
