I\'m trying to split my rails project in a front-end for regular users and a back-end for admins. Therefore i have created a namespace \'admin\' so that i can easily control adm

    Simply "moving" Devise to the admin namespace is wrong. Devise uses controllers like Devise::SessionsController and that cannot be "moved".

    I usually create my own controllers and inherit them from Devise:

    class Admin::SessionsController < ::Devise::SessionsController
      layout "admin"
      # the rest is inherited, so it should work
    end
    

    And configure this in config/routes.rb:

    devise_for :admins, :controllers => { :sessions => "admin/sessions" }
    

    Or you could change the layout only, by making the layout a bit more complex:

    class ApplicationController < ActionController::Base
    
      layout :layout
    
      private
    
      def layout
        if devise_controller? && devise_mapping.name == :admin
          "admin"
        else
          "application"
        end
      end
    
    end

    Both Jack Chu and iain solutions should solve the problem plus generating your views in order to customize the layout of the login form.

    So in your config/routes.rb you should have

    scope '/subfolder' do
       devise_for :admins, :controllers => { :sessions => "subfolder/sessions" }
    end
    
    namespace :subfolder do
      match '/', :to => 'subcontroller#action'
    end
    

    Remember di create your own controllers for sessions as you are already doing. Probably you will need to generate your views, too by using rails generate devise:views

    Check this for any doubt on devise tasks.

    If you want to put your devise views in views/admin/admins/ and your controllers in controllers/admin/admins/:

    your sessions_controller.rb in controllers/admin/admins:

    class Admin::Admins::SessionsController < ::Devise::SessionsController
      layout "admin/connection"
    end
    

    routes.rb :

    namespace :admin do |admin|
        devise_for :admins, :controllers => { :sessions => "admin/admins/sessions" }
    end
    

    Generating devise views :

    rails g devise:views admin/admins

    How about specifying devise the path to take, place this outside your namespace.

    devise_for :users, path: 'admins'
    

    This will generate the following routes

    new_user_session          GET      /admins/sign_in(.:format)          devise/sessions#new
    user_session              POST     /admins/sign_in(.:format)          devise/sessions#create
    destroy_user_session      DELETE   /admins/sign_out(.:format)         devise/sessions#destroy
    user_password             POST     /admins/password(.:format)         passwords#create
    new_user_password         GET      /admins/password/new(.:format)     passwords#new
    edit_user_password        GET      /admins/password/edit(.:format)    passwords#edit
                              PUT      /admins/password(.:format)         passwords#update
    cancel_user_registration  GET      /admins/cancel(.:format)           registrations#cancel
    user_registration         POST     /admins(.:format)                  registrations#create
    new_user_registration     GET      /admins/sign_up(.:format)          registrations#new
    edit_user_registration    GET      /admins/edit(.:format)             registrations#edit
                              PUT      /admins(.:format)                  registrations#updat
                              DELETE   /admins(.:format)                  registrations#destroy
    

    You don't have to change anything in that case, if this is what you are looking for.

    Happy Coding :)

    In addition to the first solution of the answer of iain i had to generate views of devise or else it throws a template missing exception.

    generate views with

    rails g devise_views
    

    The views will be located in views>devise. Move the created map 'sessions' to the map views>admin

    How about just moving the devise_for method into a scope:

    scope '/admin' do
      devise_for :admins
    end
    

    With namespace, the controllers will try to look for an Admin::SessionController that wont exist. With scope it doesn't, so that should work.
