Rails - Jul 2006 - Agile Web Dev on Rails - ActiveRecord::RecordNotFound Prob

Hi there

I''ve also made a start on the Agile Web Dev using Rails book! 
I''ve been
hit with a problem when hitting the ''Add to Cart'' button - I
get the
following error message:

ActiveRecord::RecordNotFound in StoreController#add_to_cart
Couldn''t find Product without an ID
RAILS_ROOT: ./script/../config/..

Application Trace | Framework Trace | Full Trace
D:/Ruby/InstantRails/ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.2/lib/active_record/base.rb:939:in
`find_from_ids''
D:/Ruby/InstantRails/ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.2/lib/active_record/base.rb:382:in
`find''
#{RAILS_ROOT}/app/controllers/store_controller.rb:11:in `add_to_cart''

It seems to me that the id of the item is not been passed in - my 
storecontroller code looks like this:

# add a product to the cart
  def add_to_cart

    @cart = find_cart
    @product = Product.find(params[:id])
    @cart.add_product(@product)

  end

It''s not obvious to me where the id is supposed to be set / got from? 
Can anybody help?

Thanks,
Dave

Oops!! Found it!! The button code in my index.rhtml page was missing '',
:id => product %>''...

Dave,

Does your app/views/store/index.html file have the ":id => product"
as
mentioned in the book?  (Pg 113 of the PDF)
