How to program a Sort feature

Question

I'm working on Ruby on rails 2.3.4 and I'm trying to develop a Sort feature on my website's search page(its url is /anuncios/buscar).

What I tried is to create a "map" on routes file:

map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance'

Then, I wrote this on the view:

<%=  link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path(@announcements) %>

And finally, I created a method in the controller, as is specified on the routes' line:

  def search_filer_relevance
    raise params.inspect
  end

First of all, as I'm sorting search results, I'd like to keep them in their public variable called @announcements. Please help me do this.

An the other thing is that when I click the link I get an error due its trying to access the Show action instead of search_filter_relevance as specified in routes. Why is this happening?

EDIT:

It seems that I have a conflict between some of my lines at routes.rb file.

There more than one line that calls the same path. For example:

  map.search "/anuncios/buscar", :controller => 'announcements', :action => 'search'
  map.power_search "/anuncios/buscar", :controller => 'announcements', :action => 'power_search'
  map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance'

So if I click the Sort link I'll be redirected to the Search action instead of the 'search_filter_relevance'. But, if I change its path to another thing(for example: "anuncios/buscar_2") it will execute the action I want but it will ask me to create a template "buscar_2" for that, and I don't want to do this.

I just want to have a link button that when is clicked a table is sorted. That's all.

Any ideas?

The error is because the route helper method is search_filter_relevance_path.

You can run rake routes to see all of the routes and methods you have set up.

As for the sorting, searchlogic already exists, so I'd have to have a really good reason to reinvent the wheel.
