Unable to Seed Data for Authlogic

When I run rake db:seed in my Rails 3 application I get the error:

rake aborted!
undefined method 'find_or_create_by_first_name_and_last_name_and_role_and_email_and_password_and_password_confirmation'

Below are my create_users.rb and seeds.rb files respectively. Why isn't the find_or_create_by_* method being dynamically created?

def self.up
    create_table :users do |t|
      t.string :first_name, :null => false
      t.string :last_name, :null => false
      t.string :role, :null => false
      t.string :email, :null => false
      t.string :crypted_password, :null => false
      t.string :password_salt, :null => false
      t.string :persist开发者_C百科ence_token, :null => false
      t.string :current_login_ip
      t.string :last_login_ip
      t.datetime :current_login_at
      t.datetime :last_login_at

      t.timestamps
    end
  end

User.find_or_create_by_first_name_and_last_name_and_role_and_email_and_password_and_password_confirmation(...)

According to the docs:

This dynamic finder is called with find_or_create_by_ and will return the object if it already exists and otherwise creates it, then returns it. Protected attributes won’t be set unless they are given in a block. (emphasis mine)

I'm guessing password and password_confirmation are protected attributes.

You are missing "and" between role and email

User.find_or_create_by_first_name_and_last_name_and_role_and_email_and_password_and_password_confirmation(...)
