将订单添加到我的交付表的简单方法，而无需转到我的订单编辑页面来执行此操作？

Question

我是ASP.Net MVC的新手，而我正在尝试的是找到一种向Orders表添加多个Delivery的简单方法。目前，我可以添加 Orders到Delivery表的唯一方法是通过我的Order Edit View。这是非常耗时的，因为我必须经历多次点击。

因此，在创建Delivery之后，我会定向到我的Delivery Detail View，在那里我可以看到我的Delivery和Orders与Delivery相关联，但我可以将Orders添加到Delivery的唯一方法是，如果我转到Edit Order View我将delivery_id链接到Order的地方。

我现在所做的是，我在Delivery Details View上添加了一个按钮，将我带到Order Index View的所有Orders，然后我设置了delivery_id点击Edit Order为每个Order我希望成为Delivery的一部分，然后在那里进行链接。这基本上是一个接一个地完成的。

我希望能够将多个Orders添加到特定Delivery，而无需经过该过程。

如果有人可以为此提出更简单的解决方案，我将非常感激！

您可以将所有订单的选中列表框添加到创建和编辑交付的视图中。

从表示您想要显示和编辑的视图模型开始

public class OrderVM
{
  public int ID { get; set; }
  public string Name { get; set; }
  public bool IsSelected { get; set; }
}
public class DeliveryVM
{
  public int? ID { get; set; }
  public int DriverID { get; set; }
  public SelectList DriverList { get; set; }
  public List<OrderVM> Orders { get; set; }
}

控制器

public ActionResult Create()
{
  DeliveryVM model = new DeliveryVM()
  {
    DriverList = new SelectList(db.Drivers, "DriverID", "First_Name"),
    Orders = db.Orders.Where(...).Select(o => new OrderVM()
    {
      ID = o.OrderID,
      Name = // build the display string you want based on other properties
    }).ToList()
  };
  return View(model);
}
public ActionResult Create(DeliveryVM model)
{
  Delivery delivery = new Delivery()
  {
    DriverID = model.DriverID,
    // map other properties of the view model to the data model
    Dispatched_Date = DateTime.Now, // set here, NOT in the GET method
    ....
  }
  db.Deliverys.Add(delivery);
  db.SaveChanges();
  // save the selected orders based on the ID of the Delivery object
  IEnumerable<int> selectedOrders = model.Orders.Where(o => o.IsSelected).Select(o => o.ID);
  foreach (int ID in selectedOrders)
  {
    Order order = db.Orders.Where(o => o.OrderID == ID).FirstOrDefault();
    order.DeliveryID = delivery.DeliveryID;
    db.Orders(order).State = EntityState.Modified
  }
  db.SaveChanges();
  // redirect
}

在视图中

@model DeliveryVM
@using (Html.BeginForm())
{
  @Html.DropDownListFor(m => m.DriverID, Model.DriverList, "-Please select-")
  ....
  for(int i = 0; i < Model.Orders.Count; i++)
  {
    @Html.HiddenForFor(m => m.Orders[i].ID)
    @Html.CheckBoxFor(m => m.Orders[i].IsSelected)
    @Html.LabelFor(m => m.Orders[i].IsSelected, Model.Orders[i].Name)
    // include hidden input for the name if you likely to return the view
  }
  <input type="submit" ../>
}

除了将现有对象的值映射到视图模型之外，Edit方法将类似，而在POST方法中，您调用数据库以获取现有对象并从视图模型更新其属性。

附注：您的数据模型似乎包含许多DateTime和属性，这些属性不应该是可编辑的，因此不应包含在视图模型中。不应在保存之前立即在GET方法中设置Dispatched_Date等属性。此外，您通过使用[Bind]属性打开了自己的优势 - 您包含了所有属性，因此恶意用户可以轻松发布导致您的应用失败的无效日期。使用视图模型意味着您永远不需要使用属性
