I have this line of code:
<%= link_to "Add to cart", :controller => "car", :action => "add_to_cart", :car => car %>
when im in the add_to_cart method...how can i call the :car please?
@car = Car.new(params[:car])
That doesn't work because it says that I'm trying to stringify it.
I don't understand what's wrong; because I used this to create new users and it worked fine.
By the way, car is my car object.
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).
You probably don't want to pass the car object as a parameter, try just passing car.id. What do you get when you inspect(params) after clicking "Add to cart"?
