Devise and Rails - ArgumentError in Devise::RegistrationsController#create

When a new user submits a new user registration form they get the below error message. I suspect it because the devise/registrations_controller.rb doesn't exist. Do I need to create this folder structure and controller or can I modify the routes.rb to avoid searching for a non-existent controller? Error: ``` ArgumentError in Devise::RegistrationsController#create wrong number of arguments (0 for 1) Rails.root: C:/Users/COMPAQ/Documents/NetBeansProjects/RailsBlog Parameters: {"utf8"=>"✓", "authenticity_token"=>"xxxxxxxxxxxxxxxxxxxxxx/c=", "user"=>{"email"=>"foo@bar.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Sign up"} ``` routes.rb: ``` RailsBlog::Application.routes.draw do devise_for :users ``` User.rb (model): ``` class User < ActiveRecord::Base # Include default devise modules.
