load/unload models/controllers and routes


I am trying to create routes at runtime but I am finding this a but of a challenge. I can get it to register as a route using the code below but then when url_for( with_url_options ) is called it throws an on any different fout error:

No route matches {:action=>“index”, :controller=>“admin/scientific_review_processes__1__1s”

When I try to load a different meta model/controller/route I have to stop/start the server and it will work. I want to be able to load and unload controllers/models and routes at runtime but I have yet to make this work correctly.

    def create_route(table_name)

    #  if Rails.application.routes.named_routes.routes["admin_#{table_name}".to_sym].nil?
        Rails.application.routes.disable_clear_and_finalize = true

          Rails.application.routes.draw do
            namespace :admin do
              resources table_name.to_sym do as_routes end
      #  ActiveSupport.on_load(:action_controller) {Rails.application.routes.finalize! }
    #  end

Does anyone know what would make such a thing work in a runtime environment?

Thanks in advance, Mark
