In your application_controller.rb

class ApplicationController < ActionController::Base
before_action :configure_strong_params, if: :devise_controller?

end

Now in your registration form you can use address_attributes & devise signup params will accept this.

class RegistrationsController < Devise::RegistrationsController
 skip_before_filter :require_no_authentication, only: :create
 #other codes 
end
