Custom Devise routes

Question

Using devise (3.2.2)
Using rails (4.0.2)

Working on developing an API which only has the need for only certain routes. I have the following in my routes.rb:

devise_for :users, path: '/users', controllers: {
  sessions: 'v1/custom_devise/sessions',
  passwords: 'v1/custom_devise/passwords'
}

Great! Now we have all these routes:

              Prefix Verb    URI Pattern                    Controller#Action
    new_user_session GET     /users/sign_in(.:format)       v1/custom_devise/sessions#new
        user_session POST    /users/sign_in(.:format)       v1/custom_devise/sessions#create
destroy_user_session DELETE  /users/sign_out(.:format)      v1/custom_devise/sessions#destroy
       user_password POST    /users/password(.:format)      v1/custom_devise/passwords#create
   new_user_password GET     /users/password/new(.:format)  v1/custom_devise/passwords#new
  edit_user_password GET     /users/password/edit(.:format) v1/custom_devise/passwords#edit
                     PATCH   /users/password(.:format)      v1/custom_devise/passwords#update
                     PUT     /users/password(.:format)      v1/custom_devise/passwords#update

But I do not want or need these routes:

    new_user_session GET     /users/sign_in(.:format)       v1/custom_devise/sessions#new
   new_user_password GET     /users/password/new(.:format)  v1/custom_devise/passwords#new
  edit_user_password GET     /users/password/edit(.:format) v1/custom_devise/passwords#edit

So I thought I will just create my own routes as per the documentation. So I changed my routes.rb:

devise_scope :user do
  post   '/users/sign_in'  => 'custom_devise/sessions#create',  as: :user_session
  delete '/users/sign_out' => 'custom_devise/sessions#destroy', as: :destroy_user_session

  post  '/users/password'  => 'custom_devise/passwords#create', as: :user_password
  put   '/users/password'  => 'custom_devise/passwords#update', as: nil
  patch '/users/password'  => 'custom_devise/passwords#update', as: nil
end

Now my routes look perfect, just the way I want them:

              Prefix Verb    URI Pattern                   Controller#Action
        user_session POST    /users/sign_in(.:format)      v1/custom_devise/sessions#create
destroy_user_session DELETE  /users/sign_out(.:format)     v1/custom_devise/sessions#destroy
       user_password POST    /users/password(.:format)     v1/custom_devise/passwords#create
                     PUT     /users/password(.:format)     v1/custom_devise/passwords#update
                     PATCH   /users/password(.:format)     v1/custom_devise/passwords#update

But now my requests fail, with:

 AbstractController::ActionNotFound:
   Could not find devise mapping for path "/users/sign_in".
   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]

I have tried many variations, to no avail.

UPDATE: This may be overkill, but here is an sample example app demonstration this. Not sure if I am doing something wrong or if this might be a devise bug.

You are missing the GET for the sign in action that shows you the login form.. you only have the session creation, fix it like such (you :

devise_scope :user do
  get   '/users/sign_in'  => 'custom_devise/sessions#new',  as: :new_user_session      
  post   '/users/sign_in'  => 'custom_devise/sessions#create',  as: :user_session
  delete '/users/sign_out' => 'custom_devise/sessions#destroy', as: :destroy_user_session

  post  '/users/password'  => 'custom_devise/passwords#create', as: :user_password
  put   '/users/password'  => 'custom_devise/passwords#update', as: nil
  patch '/users/password'  => 'custom_devise/passwords#update', as: nil
end
