Flexible authentication solution for Rails with Warden.

ActionDispatch::Routing::Mapper#authenticated

Allow you to route based on whether a scope is authenticated. You
can optionally specify which scope and a block. The block accepts
a model and allows extra constraints to be done on the instance.

  authenticated :admin do
    root to: 'admin/dashboard#show', as: :admin_root
  end

  authenticated do
    root to: 'dashboard#show', as: :authenticated_root
  end

  authenticated :user, lambda {|u| u.role == "admin"} do
    root to: "admin/dashboard#show", as: :user_root
  end

  root to: 'landing#show'
