How to get link_to in Rails output an SEO friendly url?

My link_to tag is:

<%= link_to("My test title",{:controller=>"search", :action=>"for-sale", :id=> listing.id, :title => listing.title, :search_term => search_term}) %>

and produces this ugly URL:

http://mysite.com/search/for-sale/12345?title=p开发者_如何转开发remium+ad+%2B+photo+%5Btest%5D

How can I get link_to to generate:

http://mysite.com/search/for-sale/listing-title/search-term/12345

Been trying this a few different ways and cannot find much online, really appreciate any help!

Tahe a look at this

add this in your config/routes.rb

map.connect ':controller/:action/:title/search_item/:id', :controller=>'search', :action=>'for_sale' 

restart your server and check. Hope that helps :)

You need to change the URL structure in routes.rb to match what you want the URL to look like, and parse the parameters accordingly in your controller method's args.
