我创建了订单类，您可以进行订单和查看订单。但是现在我正在尝试创建一个＆＃34;返回＆＃34;基本上允许用户输入退货原因然后打印原因/发票的页面。我有订单创建表单但是我不知道如何链接2来说这个返回属于这个订单所有我能做的就是创建一个没有链接的泛型返回。我已经建立了关系我只是不确定如何将退货连接到特定订单。我知道这是一个基本问题，我无法在网上找到任何帮助我的东西。我是学生，解释会非常有益，因为我需要在其他方面使用类似的方法
以下是我的控制器，可以查看 MyOrders 和 ReturnsForm
namespace T_shirt_Company_v3.Controllers
{
public class MyOrderController : Controller
{
TshirtStoreDB db = new TshirtStoreDB();
/// <summary>
/// Returns a list of Orders made by the user
/// </summary>
/// <param name="date">choose date period viewing orders</param>
/// <param name="order">Orders being viewed</param>
/// <returns></returns>
[Authorize]
public ActionResult Index(string date, Order order)
{
TshirtStoreDB db = new TshirtStoreDB();
string currentUser = this.User.Identity.GetUserName();
List<T_shirt_Company_v3.ViewModels.MyOrdersViewModel> list = (from o in new TshirtStoreDB().Orders
.Where(o => o.Username == currentUser)
.OrderByDescending(o => o.OrderDate)
.Select(o => new MyOrdersViewModel()
{
OrderId = o.OrderId,
Address = o.Address,
FirstName = o.FirstName,
LastName = o.LastName,
City = o.City,
OrderDate = o.OrderDate,
PostalCode = o.PostalCode,
Total = o.Total,
HasBeenShipped = o.HasBeenShipped,
PostageList = o.PostageList,
Details = (from d in o.OrderDetails
select new MyOrderDetails
{
Colour = d.Product.Colour,
Quantity = d.Quantity,
Title = d.Product.Title,
UnitPrice = d.UnitPrice
}).ToList()
}).ToList() select o).ToList();
if (date != null)
{
DateTime today = DateTime.Now.AddDays(Convert.ToInt32(date) * -1);
return View(list.Where(x => x.OrderDate >= today).ToList());
}
return View(list);
}
public ActionResult ReturnsForm()
{
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult ReturnsForm([Bind(Include = "ReturnId,OrderId,ReturnDate,Reason")] returnDetails returnDetails)
{
if (ModelState.IsValid)
{
if (returnDetails != null)
{
returnDetails.ReturnDate = DateTime.Now;
}
db.returnDetails.Add(returnDetails);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(returnDetails);
}
}
}
和我的 MyOrders 视图

键 在返回类

public virtual Order order { get; set; }
在订单类
中public int ReturnId { get; set; }
public virtual returnDetails returns { get; set; }
答案 0 :(得分：1)
在MyOrders.cshtml视图中，您需要生成指向ReturnsForm()方法的链接并传递订单的ID
@foreach (var m in Model)
{
....
@Html.ActionLink("Return Order", "ReturnsForm", new { orderID = m.OrderId })
}
并将方法修改为
public ActionResult ReturnsForm(int orderID)
{
returnDetails model = new returnDetails()
{
OrderId = orderID
};
return View(model );
}
然后在ReturnsCreate.cshtml视图中，为该属性添加隐藏的输入
@Html.HiddenFor(m => m.OrderId )
当您回发模型时，值也将被绑定。
附注：上面的代码使用了您的数据模型，但这种做法很糟糕，您应该使用Returns的视图模型
