Rails 3.1.1 has_secure_password digest can't be blank

I have been playing around with has_secure_password and I ran into a problem. My test for the create action in my UsersController was not working passing. So I started playing around in the console and realized that the password was not being converted to a has and saved in password_digest field.

When I try to create a user from the console the following happens.

irb(main):031:0> u = User.new(:email => "test1@test.com", :password => "test", :password_confirmation => "test")
=> #<User id: nil, email: "test1@test.com", password_digest: nil, created_at: nil, updated_at: nil>
irb(main):032:0> u.save
=> false
irb(main):033:0> u.errors
=> #<ActiveModel::Errors:0x00000100cde500 @base=#<User id: nil, email: "test1@test.com", password_digest: nil, created_at: nil, updated_at: nil>, @messages={:password_digest=>["can't be blank"]}>

I am not sure what I am doing wrong. It looks like the password_digest attribute never gets assigned. If I create a user object with no attributes and assign each attribute individually I get the same error.

Here is my model

class User < ActiveRecord::Base
  has_secure_password
  attr_accessible :email, :password, :password_confirmation
end

Thanks for the help in advance.
