Demonstration of autoloading issue in ActiveSupport::Dependencies.

Edit Gemfile to switch between patched and unpatched versions of ActiveSupport.

# Simple case: load class within first folder

#   #

puts Blog::Post.new.inspect

# Another simple case: load nested class within folders

#   #

puts Blog::Admin::PostsController.hardcoded.inspect

# It gets complicated: attempts to load Blog::Admin::Post (similar to inherited_resources)

# We would expect either a NameError or have it return Blog::Post. Instead we get:

#   /Users/sam/.rvm/gems/ruby-1.9.2-p180/bundler/gems/rails-12786518f1f7/

#      activesupport/lib/active_support/dependencies.rb:476:in `load_missing_constant':

#      Blog is not missing constant Post! (ArgumentError)

puts Blog::Admin::PostsController.autodetect.inspect

# Interestingly, this last line works if we run it first (before Blog::Post is loaded)

# but then fails if we run it again (since Blog::Post is now loaded).
