I am in the correct directory, but I am now seeing an error pertaining to the prescence validations I used when following the video
/Users/salvi/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/activemodel-4.1.4/lib/active_model/validations/validates.rb:118:in `rescue in block in validates': Unknown validator: 'PrescenceValidator' (ArgumentError)
