Hi, I am implementing shopping cart and getting error in add_to_cart. The error is: ActiveRecord::AssociationTypeMismatch in StoreController#cart Product expected, got Fixnum The add_to_cart method is: def add_to_cart product = Product.find(params[:id]) @cart = find_cart @cart.add_product(product) redirect_to(:action =>''display_cart'') rescue logger.error("Attempt to access invalid product #{params[:id]}") flash[:notice] =''Invalid product'' redirect_to(:action => ''index'') end render_text product.id is giving id of the product. Can anyone tell me how to solve it? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
