Routing for custom controller actions

Question

I'm trying develop a reddit style site which allows users to vote on links. The voting feature goes beyond basic CRUD supported by resources :links I've written the up/down actions and linked them to the view but I'm not sure how to handle routing. Could someone demonstrate how I would route to custom controller actions? I've attached my files below. Thanks

I receive this error when I load the view

No route matches {:controller=>"links", :action=>"up"}

You can extend resources mapping with this example:

resources :links do
  member do
    match :up
    match :down
  end
end

These actions must be available in LinksController class (same as new, create...). More in Ruby on Rails Guide: Rails Routing.

Tip: actions changing state of entity should not use GET verb. This is because search bots or accelerator may follow your voting links. You link should be:

<%= link_to "+", up_link_path, :method => :post, :rel => 'nofollow' %>

And in controller should modify your entinty only inside if request.post?. You should still support GET to not cause 404s.

I updated the routes file and ran 'rake routes' but this solution didn't work. I also replaced 'post' with 'put' since I'm trying to update attributes, didn't solve it either.

I changed 'post' to 'put' and also modified my view links <%= link_to '+', up_link_url(link), :method => :put %> <%= link.points %> Thanks for the help.
