for reason unknown me heroku not linking admins/registrations/new.html.erb instead it's linking devise/registrations/new.html.erb it's reading 'name' attribute showing undefined method error.

my controllers/admins/registrations_controller.rb file looks this:

class admins::registrationscontroller < devise::registrationscontroller  end 

my routes.rb file looks this:

myfirstapp::application.routes.draw   "users/show"    devise_for :admins, :controllers => { :registrations => "admins/registrations", :sessions => "admins/sessions" }       "/admins/sign_up" => "admins/registrations#new"       "/admins/sign_in" => "admins/sessions#new"   end    resources :posts     devise_for :users   match 'users/:id' => 'users#show'     root :to => 'pages#home'   'about' => 'pages#about'  end

i'd appreciate can get! first time creating app apologize if question dumb i'm stuck , need help!

first check gitrepo make sure file, or related file, reason has been ignored.

and if isn't issue nuke heroku project , start over.

heroku has special way of not creating new repos/projects correctly. fail rate pretty small, might have rolled snake eyes.

if doesn't work post production.rb , development.rb.
