Rails 4 Friendship Routes

So the 'Creating the Friendship' section is working on renaming devise routes for our purposes. Specifically changing sign_in to login. Here is their suggested code.

as :user do
    get "/register", to: "devise/registrations#new", as: :register
    get "/login", to: "devise/sessions#new", as: :login
    get "/logout", to: "devise/sessions#destroy", as: :logout
end

devise_for :users, skip: [:sessions]

as :user do
    get "/login" => 'devise/sessions#new', as: :new_user_session
    post "/login" => 'devise/sessions#create', as: :user_session
    delete "/logout" => 'devise/sessions#destroy', as: :destroy_user_session
end

In Rails 4 this doesn't work. Per this Devise issue, "Rails 4 router doesn't support identically named routes with conditional logic"

Does anyone have a workaround for this?

Actually I'm just an idiot. Devise creates a resource when you first install devise. This lesson has you change it but in Rails 4 you can't have matching resource names. So the code actually looks like this (in Rails 3.2.6 aka the video)

devise_for :users

as :user do
    get "/register", to: "devise/registrations#new", as: :register
    get "/login", to: "devise/sessions#new", as: :login
    get "/logout", to: "devise/sessions#destroy", as: :logout
end

devise_for :users, skip: [:sessions]

as :user do
    get "/login" => 'devise/sessions#new', as: :new_user_session
    post "/login" => 'devise/sessions#create', as: :user_session
    delete "/logout" => 'devise/sessions#destroy', as: :destroy_user_session
end

The solution for Rails 4 is to delete the first devise_for :users
