ActionNotFound for root :to => "Devise::Sessions#new"

[moritz]

I am trying to route to the sign_in page by using

DeviseExample::Application.routes.draw do
devise_for :users
root :to => "Devise::Sessions#new"

but get the following error (in devise 1.1.2):

Started GET "/" for 127.0.0.1 at 2010-09-20 09:42:28 -0700
Processing by Devise::SessionsController#new as HTML
Completed in 0ms

AbstractController::ActionNotFound
(AbstractController::ActionNotFound):

Using devise 1.2 that changes to:

Started GET "/" for 127.0.0.1 at 2010-09-20 09:20:21 -0700
Processing by Devise::SessionsController#new as HTML
[Devise] Could not find devise mapping for /.
Completed in 0ms

AbstractController::ActionNotFound (Could not find devise mapping
for /.):

How else can I accomplish this? Am I trying something impossible?

I'm not sure pointing "/" to Devise session would be the best, cause every time a user access "/", if he's signed in, it's going to have a redirect.

Take a look on the wiki here to have some more info: http://github.com/plataformatec/devise/wiki/How-To:-Change-the-default-sign_in-and-sign_out-routes

You are right, that was backwards. After a bit of refactoring, I came
up with

devise_for :users
devise_scope :user do
root :to => "users#current"
get '/users/current' => "users#current", :as => :current_user
resources :users, :only => [:index, :show]
end

to do what I was looking for.

I could not use

devise_for :users do
root :to => "users#current"
get '/users/current' => "users#current", :as => :current_user
resources :users, :only => [:index, :show]
end

due to route ordering. '/users/:id(.:format)' would be before '/users/
sign_in(.:format)', for example.

There are still aspects that I don't understand. In particular, if I
use

devise_scope :users do ...

instead of

devise_scope :user do ...

I get the error

Started GET "/" for 127.0.0.1 at 2010-09-27 10:08:42 -0700
Processing by UsersController#current as HTML

Completed in 0ms

AbstractController::ActionNotFound

even though routes look exactly the same.

Any further insight would certainly be welcome. Thanks in advance.

That's because Devise uses the singular name as it's mapping name, so you'll always end up with :user as the scope. In devise_scope / authenticate methods you need give the scope itself, Devise won't try to find it.
