I am pretty close to figuring this out...

I've got this in my product show page....I'm trying to pass user_id & product_id to my products controller, add_to_cart method...


<%= button_to  'Add to Cart', {:controller => "products", :action => "add_to_cart", :user_id=> session[:user_id], :product_id => @id   } , :method=>:post  %>

on the controller...

def add_to_cart(user_id, product_id)


@cart = Cart.new(user_id, product_id )
#

end

I get the error, 

"wrong number of arguments (given 0, expected 2)"



Any suggestions?

Thanks,

Joe
