Does anyone know why it's returning only 1 item? There are 2 items in my cart. Here is the "item_dict" variable:

 cart_items = CartItem.objects.filter(user=current_user)
 for cart_item in cart_items:
        total  = (cart_item.product.price * cart_item.quantity)
        quantity  = cart_item.quantity

        item_dict = f"""
            <item>
                <id>{cart_item.product.id}</id>\r\n
                <description>{cart_item.product.name}</description>\r\n
                <quantity>{cart_item.quantity}</quantity>\r\n
                <amount>{cart_item.product.price}</amount>\r\n
            </item>
            """
        return HttpResponse(item_dict)

In my HttpResponse(item_dict) it is returning me only 1 item

Meu objetivo é poder devolver todos os itens do meu carrinho no meu XML

I don't know what I'm doing wrong.

CodePudding user response：

Most likely reason is the return statement is inside the for loop, so the loop will always return on the first iteration. You probably need something more like:

returnable_string = ''

for cart_item in cart_items:
    returnable_string  = f"""
        <item>
            <id>{cart_item.product.id}</id>\r\n
            <description>{cart_item.product.name}</description>\r\n
            <quantity>{cart_item.quantity}</quantity>\r\n
            <amount>{cart_item.product.price}</amount>\r\n
        </item>
        """

return HttpResponse(returnable_string)

Although this example doesn't deal with adding up the total and quantity, notice that the return statement is outside the for loop.
