Controller action methods do not take parameters. You get the parameters from the `params` hash. Also, as was mentioned, do not send user_id as a param. It is a security error, and you don't need to because you can access the session in the controller:

@cart = Cart.new(user_id, product_id)

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...
@cart = Cart.new(user_id, product_id )#endI get the error,"wrong number of arguments (given 0, expected 2)"
Any suggestions?
