When deploying to cloud-foundry its advised to change from 'jquery-rails' gem to 'cloudfoundry-jquery-rails'
# For Ruby 1.9 Cloud Foundry requires a tweak to the jquery-rails gem.
# gem 'jquery-rails'
gem 'cloudfoundry-jquery-rails'
so that jquery can seamlessly work with cloudfoundry.
What are those fixes refered to in this that are necessary to make it work on cloud-foundry?
The documentation for this is a little out of date and is in the process of being updated. For Rails 3.1 this may well be the case, but certainly not for 3.2, it should work fine as is.
