ruby on rails - Devise within namespace -

i'm trying split rails project in front-end regular users , back-end admins. therefore have created namespace 'admin' can control admin specific controller methods/layouts/authentication in map admin.

i'm using devise register/authenticate admins only. because used admins i'm trying move devise admin namespace.

i not find looking in documentation of devise tried in routes.rb:

namespace 'admin'do    devise_for :admins end 

i tried make custom devise::sessions controller didn't seem work out.

does know how this? should use regular routes devise custom(admin) layout?

simply "moving" devise admin namespace wrong. devise uses controllers devise::sessionscontroller , cannot "moved".

i create own controllers , inherit them devise:

class admin::sessionscontroller < ::devise::sessionscontroller   layout "admin"   # rest inherited, should work end 

and configure in config/routes.rb:

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

or change layout only, making layout 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
