pass parameter by link_to ruby on rails

Question

I have this line of code:

<%= link_to \"Add to cart\", :controller => \"car\", :action => \"add_to_cart\", :car => car %>

wh

Answer 1

Maybe try this:

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

But I'd really like to see where the car object is getting setup for this page (i.e., the rest of the view).
