How to dynamically add a route to a scoped resource in Rails3?

right now I am trying to generalize some of my code. So far it went well, I wrote a few mixins which I can dynamically add to Controllers or Models in order to get things done while obeying DRY.

But with my "Searchform-Helper" I hit a corner in which, right now, I am a bit clueless.

I have a mixin 'SearchIndexController' which adds the methods needed to search for data within a searchindex-table.

After including the mixin I can initialize search-actions within the according controller calling this method:

def init_searchaction(object, name=nil)
  singular = object.to_s.classify
  plural   = singular.pluralize
  name = "search_#{singular}".to_sym if name.nil?

  unless self.respond_to?(name)
    define_method(name) do
      # init
      success=false

      #TODO 
      # >>> DRAW NEW ROUTE TO THIS ACTION <<<

      # evaluate searchform input for Searchindex-Call
      needle = params[:query]

      success, x, notice = execute_search("#{singular}", needle)
      # send selected/filtered data to page
      respond_to do |format|
        format.js {
          render :update do |page|
            page.call "sidx_updateSearchResultContentAtIdTag", "##{plural.downcase} tbody", "#{rend开发者_JAVA百科er x}" if success
            page.call "sidx_updateNotice", success, "#{notice}"
            page.call "sidx_stopSpinner"
          end
        }
      end
    end
  else
    logger.warn("#{__FILE__}:#{__LINE__}:#{self.to_s}: search-action for '#{self.class.name}' can not be created, it already exists!")
  end
end

So lets say I have a User-Controller. Within the Userform I have the need to search for several objects. Lets assume I want to be able to search for users, departments and clients... with my mixin I'd just have to initialize the searchactions like this:

init_searchaction :user
init_searchaction :department
init_searchaction :client, :find_clients

these would create actions within the including controller that are called

search_user
search_department
find_clients

The only thing missing is a way to get a route for them. I don't want to have to define the route upfront. I just want to 'init_searchaction' and have the mixin create the necessary route.

So... would it be possible to add the route to the accoring search-action from withing the mixins init_searchaction method dynamically? I think the necessary code would be placed at the #TODO mark in the code example above. But I still haven't found out how to do it... I mean, actually I would be surprised if it would not be possible.

Would anyone have an idea as how to do this? Thanks in advance for any idea that leads to the solution!

You can add work around standart dynamic route

match ':controller(/:action(/:id(.:format)))'

change it to your goals and enjoy :)
