I'm trying to run the part where the effect is implemented in
application hightlight depot but is not working, I tried to download the
codes on the site but it also does not work so someone step
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>
