Answer 1

Try:

<%= link_to "Add to cart", {:controller => "car", :action => "add_to_cart", :car => car.id }%>

and then in your controller

@car = Car.find(params[:car])

which, will find in your 'cars' table (as with rails pluralization) in your DB a car with id == to car.id

hope it helps! happy coding
