Hitting a road block on the Ruby videos

Hi there everyone, I have tried almost everything to fix this issue I'm having. I have just started to learn about ruby and found out about these videos, I have gotten as far as "Generating the user model", as far as I'm aware devise installed properly without spitting any errors, everything else is installed and I followed the exact steps on the video.

This is the error that it spits out when I do rake db:migrate--trace, but it doesn't really make much sense to me, hopefully someone can help me out, I don't have much time on my hands to do the course so hopefully I don't have to start all over again.

C:\Sites\projects\treebook>rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!

I stole this from staffer Andrew Chalkley's post in a similar thread but I had the exact same problem and it worked for me.

add 

gem 'bcrypt-ruby', '~> 3.0.0', :require => "bcrypt"

to your Gemfile

Thank you for this, I tried it and it spat something about a wrong file, I restarted the project through the commit from git and it's worked perfectly.

Can you paste your user model file (user.rb)?

from treebook > app > models > 

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me
  # attr_accessible :title, :body
end

Sorry about the wait. Should check my emails more often...
