I am trying to add order list from shopping cart.
I am doing this similarly as http://www.asp.net/mvc/tutorials/mvc-music-store/mvc-music-store-part-9
db.saveChanges() has error, 'An error occurred while updating the entries. See the inner exception for details.'
When I see the order, orderId is '0'. Is it problem with this?
I am giving you some code.
Could you give me some idea?
Thanks.
//Order.cs
public class Order
{
rentalDB db = new rentalDB();
[Key] public int orderId { get; set; }
public int customerId { get; set; }
public DateTime orderDate { get; set; }
public int rentalPeriod { get; set; }
public DateTime startDate { get; set; }
public decimal total { get; set; }
public virtual Customer Customer { get; set; }
public List<OrderDetails> OrderDetails { get; set; }
}
And here is controller.
//AccountController.cs
[Authorize]
public ActionResult Order()
{
var order = new Order();
TryUpdateModel(order);
string customerName = User.Identity.Name;
if (customerName == "")
{
return RedirectToAction("LogOn", "Account");
}
int customerId = (from a in db.Customer
where a.userName == customerName
select a.customerId).Single();
order.customerId = customerId;
db.Order.Add(order);
//I added orderDate and startDate, then it is saving now.
order.orderDate = System.DateTime.Now;
order.startDate = System.DateTime.Now.AddDays(2);
db.SaveChanges();
var cart = ShoppingCart.GetCart(this.HttpContext);
cart.CreateOrder(order);
return View(order);
}
