How to write link_to method to Rails route globbing

I have a product page,I want to change the url "example.com/products/
list?category_id=1&price_id=5&type_id=2&sort_by=name&......" to

"example.com/products/list/category_id/1/price_id/5/type_id/2/sort_by/
name.....".
my routes like

  match '/products/list(/*specs)', :controller => 'products', :action
=> 'list',:as => :list_products
My controller

  @products=Product.scoped
  @products = @Product.where(Hash[*params[:specs].split("/")]) if
params[:specs]
In my views:

  Categories:
  <% Category.all.each do |category| %>
  <p><%= link_to category.name,list_products_path(:specs =>
['category', category]) %></p>
  <% end %>
  Price:
  <% Prices.all.each do |price| %>
  <p><%= link_to price.name,list_products_path(:specs => ['local',
local]) %></p>
  <% end %>
I wnat to get url like /products/list/category/1/local/2... ,but it
can only get url like /products/category/1 or /news/local/2. How to
write the link_to method to make it works? Thank you.

Setup your routes using nested resources. http://guides.rubyonrails.org/routing.html#nested-resources

After setting that up, use rake routes to find the url you need.
