hope you're enjoying you're well deserved time off. Just thought I should add that the way to ensure you have the most recent version of mongoid would be to write
gem 'mongoid', git: 'https://github.com/mongoid/mongoid.git'
This is particularly important as the gem available from rubygems.org seems to have some problems with Rails 4 whereas the github version works perfectly with it.
