Generate devise session controller

[Maddy]

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

end

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.
