I'm going through DHH's Agile Web Development with Rails for Rails 3.1. In chapter 14 they create a Users sign-in model/view/controller using the has_secure_password method. My user.rb file looks like this:

    class User < ActiveRecord::Base
      attr_accessible :name, :password_digest, :password, :password_confirmation
      validates :name, presence: true, uniqueness: true
      has_secure_password
    end

now when I go to localhost:3000/users/new I first get some kind of bcrypt-ruby error and then when I reload the page I get a undefined method `key?' for nil:NilClass

I don't know what needs to be done, mike

I think I figured out what happened. I installed bcrypt-ruby and ran bundle install but never restarted the server. Everything's working now.
