    # ==> Configuration for :confirmable

    # ==> Scopes configuration

    # ==> Mountable engine configurations
    # When using Devise inside an engine, let's call it `MyEngine`, and this engine

    # The following options are available, assuming the engine is mounted as:
    #
    #     mount MyEngine, at: '/my_engine'
    #
    # The router that invoked `devise_for`, in the example above, would be:
    # config.router_name = :my_engine
    #
    # When using OmniAuth, Devise cannot automatically set OmniAuth path,
    # so you need to do it manually. For the users scope, it would be:
    # config.omniauth_path_prefix = '/my_engine/users/auth'
    OmniAuth.config.logger = Rails.logger
  end

  # Override script_name to always return empty string and avoid looking in @env
