2. add pg gem
3. in application.rb re-add ActiveRecord
4. for all models
- inherit from ActiveRecord::Base
- get rid of Mongoid:Document line
- make migrations and put fields there

1. the default index.html does not work well in prodution mode, so do not borther to config that, just delete it and go on.

2. To put things in production mode, do

    rails g scaffold items name:string
    rake db:migrate RAILS_ENV=production
    rm public/index.html
    #change route.rb point root to items#index
    rake assets:precompile
    sudo service nginx restart
   

./config/unicorn_init.sh stop
