ruby on rails - Devise multiple users - uninitialized constant UserRegistrationsController -

i relatively new rails , trying set multiple user types devise (borrowers , lenders). followed tutorial multiple user models ruby on rails , devise have separate registration routes 1 common login route

but keep coming error "uninitialized constant userregistrationscontroller".

here code have updated basic devise , locations (some of these moved/created based on understanding of tutorial may wrong):

in: app/controllers/users/registrations_controller.rb

class userregistrationscontroller < devise::registrationscontroller def create build_resource  # customized code begin  # crate new child instance depending on given user type user_type = params[:user][:user_type] resource.rolable = child_class.new(params[child_class.to_s.underscore.to_sym])  # first check if child instance valid # cause if , parent instance valid # it's being saved @ once valid = resource.valid? valid = resource.rolable.valid? && valid  # customized code end  if valid && resource.save    # customized code   if resource.active_for_authentication?     set_flash_message :notice, :signed_up if is_navigational_format?     sign_in(resource_name, resource)     respond_with resource, :location => redirect_location(resource_name, resource)   else     set_flash_message :notice, :inactive_signed_up, :reason => inactive_reason(resource)     if is_navigational_format?     expire_session_data_after_sign_in!     respond_with resource, :location => after_inactive_sign_up_path_for(resource)   end else   clean_up_passwords(resource)   respond_with_navigational(resource) { render :new }   end  end end 

in: app/controllers/users_controller.rb

class userscontroller < applicationcontroller def show @user = user.find(params[:id]) @pins = @user.pins.page(params[:page]).per_page(20) end end 

in: app/models/borrower.rb

class borrower < activerecord::base  has_one :user, :as => :rolable   has_many :pins end 

in: app/models/lender.rb

class lender < activerecord::base  has_one :user, :as => :rolable   has_many :pins end 

in: app/models/user.rb

class user < activerecord::base # include default devise modules. others available are: # :token_authenticatable, :confirmable, # :lockable, :timeoutable , :omniauthable devise :database_authenticatable, :registerable,       :rememberable, :trackable, :validatable #:recoverable,  # setup accessible (or protected) attributes model attr_accessible :email, :password, :password_confirmation, :remember_me, :name,  :description # attr_accessible :title, :body  belongs_to :rolable, :polymorphic => true  has_many :pins  end

in: config/locales/routes.rb:

get "users/show"  resources :pins  devise_for :users, :controllers => { :registrations => 'userregistrations' } match 'users/:id' => 'users#show', :as => :user  'about' => 'pages#about' 'clothing' => 'pages#clothing' 'bags' => 'pages#bags' 'shoes' => 'pages#shoes' 'stylefeed' => 'pages#stylefeed' 'accessories' => 'pages#accessories' 'designers' => 'pages#designers'  root :to => 'pins#index'  match 'borrower/sign_up' => 'user_registrations#new', :user => { :user_type => 'borrower' } match 'lender/sign_up' => 'user_registrations#new', :user => { :user_type => 'lender' } 

i added rolabe id , rolable type users table , generated registrations controller.

does have idea going wrong? thanks!!

rails autoload failing find file class. rename userregistrationscontroller users::registrationscontroller
