Proper way of rails routing custom Users controller and devise gem - ruby-on-rails

Question

Im having a problem routing my custom Users controller and devise gem.
When i try to reach http://localhost:3000/users
<%= link_to 'Users', users_path, class: 'navbar-brand' %>
I get error:
Could not find devise mapping for path "/users". This may happen for two reasons:
1) You forgot to wrap your route inside the scope block. For example: devise_scope :user do get "/some/route" => "some_devise_controller" end
2) You are testing a Devise controller bypassing the router. If so, you can explicitly tell Devise which mapping to use: #request.env["devise.mapping"] = Devise.mappings[:user]
If i run command rake routes i get this output:
Prefix Verb URI Pattern Controller#Action
root GET / static_pages#home
new_user_session GET /users/sign_in(.:format) devise/sessions#new
user_session POST /users/sign_in(.:format) devise/sessions#create
destroy_user_session DELETE /users/sign_out(.:format) devise/sessions#destroy
user_password POST /users/password(.:format) devise/passwords#create
new_user_password GET /users/password/new(.:format) devise/passwords#new
edit_user_password GET /users/password/edit(.:format) devise/passwords#edit
PATCH /users/password(.:format) devise/passwords#update
PUT /users/password(.:format) devise/passwords#update
cancel_user_registration GET /users/cancel(.:format) devise/registrations#cancel
user_registration POST /users(.:format) devise/registrations#create
new_user_registration GET /users/sign_up(.:format) devise/registrations#new
edit_user_registration GET /users/edit(.:format) devise/registrations#edit
PATCH /users(.:format) devise/registrations#update
PUT /users(.:format) devise/registrations#update
DELETE /users(.:format) devise/registrations#destroy
user_confirmation POST /users/confirmation(.:format) devise/confirmations#create
new_user_confirmation GET /users/confirmation/new(.:format) devise/confirmations#new
GET /users/confirmation(.:format) devise/confirmations#show
users GET /users(.:format) users#index
POST /users(.:format) users#create
new_user GET /users/new(.:format) users#new
edit_user GET /users/:id/edit(.:format) users#edit
user GET /users/:id(.:format) users#show
PATCH /users/:id(.:format) users#update
PUT /users/:id(.:format) users#update
DELETE /users/:id(.:format) users#destroy
account_update PATCH /account_update(.:format) users#update
And this are my routes
root 'static_pages#home'
devise_for :users
resources :users
as :user do
patch 'account_update' => 'users#update'
get 'users' => 'users#index'
end
How to tell rails that on /users it should go to controller Users and select index page

Answer 1

You can try something like that,
devise_for :users
devise_scope :user do
end
