Generate devise session controller

Hi Folks Good morning,

Am new to rails.

I used devise in my project ,i need to write some conditions in my session controller.How can i generate devise session controller.

I have user.rb model.

Steps which i made:

  1. Generate rails g controller session

  2. Session controller generated

  3. Changes the text like,

class Users::SessionsController < Devise::SessionsController

4.In routes i have changed,

devise_for :users, :controllers => { :sessions => “users/sessions” }

While execute  i got an error:

# Routing Error

uninitialized constant Users

Try running `rake routes` for more information on available routes.

Please advice.
