My app has an order. This order has products, which is chosen in a
each product is added by a partial like this:
6. <input name="product_price" />
"Onchange" a product, the price is updated via ajax using rjs. thats
but, when I add another product, it update the first product price, of
course, because it have the same name and ID. But I can not change
this, so is there some way to get the next input element via
thnks a lot!!!
