Sorry english evil, I am learning:)
Codes
cart.rb <code> def add_product(product) current_item = @items.find {|item| item.product == product} if current_item current_item.increment_quantity else current_item = CartItem.new(product) @items << current_item end current_item end </code>
store_controller <code> def add_to_cart begin product = Product.find(params[:id]) rescue ActiveRecord::RecordNotFound logger.error("Attempt to access invalid product #{params[:id]}") redirect_to_index("Invalid product") else @cart = find_cart @current_item = @cart.add_product(product) end end </code>
Partial _cart_item.rhtml <code> <% if cart_item == @current_item %> <tr id="current_item"> <% else %> <tr> <% end %>
<td><%= cart_item.quantity %>×</td> <td><%= h(cart_item.title) %> </td> <td class="item-price"><%= number_to_currency(cart_item.price) %></td> </tr> </code>
add_to_cart.rjs
<code> page.replace_html("cart", :partial => "cart", :object => @cart)
page[:current_item].visual_effect :highlight, :startcolor => "#88ff88", :endcolor => "#114411"
</code>
