how to delete with ajax

Hello, I'm trying to create a link to delete the record of a discount in my database. I have a page that lists them, each one rendered in a partial with a delete link. I'm trying link_to_remote, but it gives me this errors:

No method responded to 28 (which is the record id)

Here is a link to my code:

Try adding a :method => :delete to the link. If you're using default resource routes, that should do the trick (also you don't need to use :action => 'destroy', but can instead pass discount_url(discount) as :url.

Are you on Rails3 (can’t access pastie from mobile)? <%= link_to ‘destroy’, product, :confirm => ‘Are you sure?’, :method => :delete, :remote => :true %>
