I'm trying to follow the instructions of the video. I executed the commands as required:

rails new store
rails g scaffold product name price:decimal --skip-stylesheets
rake db:migrate
rails g bootstrap:install
rails g bootstrap:themed products -f

of course I also put the twitter-bootstrap-rails gem into the gemfile

but when I run localhost:3000/products I get this (from the terminal where I run the server)

Started GET "/products" for at 2013-06-29 16:06:39 +0800

i've solved it thanks. Thanks to Raison D'souza's comment


Hi I keep getting:

NoMethodError in SessionsController#create
undefined method `[]' for nil:NilClass

This appears after I logged into Twitter and before redirecting back to the callback page.
