I have a blog with file up-/download via paperclip 5.1.0 and turbolinks 5.0.1. Upload without validation works fine now, but download is only working for a short period after up
New git version of paperclip gem now works with aws-sdk-s3 gem, add this to Gemfile:
#Paperclip gem 'paperclip', git: 'git://github.com/thoughtbot/paperclip.git'
