MVC 5 单个视图中的多个模型

有人可以提供一个如何在一个视图中组合两个模型的示例吗？

目前我有一个名为 RecordCard 的页面，其中包含：

@model IEnumerable<WebApplication1.Models.Weight>

这是由 AccountController 中的以下代码提供的：

public ActionResult RecordCard()
{
    var UserId = User.Identity.GetUserId();
    var weightModel = from m in db.Weights where m.UserId == UserId select m;
    return View(weightModel);
}

RecordCard 页面还包含一个绑定到以下类的表单：

public class AddWeightModel
{
    [Required]
    [DataType(DataType.Text)]
    [Display(Name = "Stone")]
    public Nullable<short> Stone { get; set; }

    [Required]
    [DataType(DataType.Text)]
    [Display(Name = "Pound")]
    public Nullable<short> Pound { get; set; }
}

但是，这是两个具有不同用途的单独模型，因此如何组合成一个包含 IEnumerable 列表和表单元素集的单个模型，这些元素最终将正确发布到 AccountController 以使用以下代码将记录添加到数据库：

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult RecordCard(Weight Model)
{
    if (ModelState.IsValid)
    {
        using (WebApplication1Entities db = new WebApplication1Entities())
        {
            Weight weight = new Weight();
            weight.UserId = User.Identity.GetUserId();
            weight.Stone = Model.Stone;
            weight.Pound = Model.Pound;
            weight.Date = System.DateTime.Now;

            db.Weights.Add(Model);
            db.SaveChanges();
        }
    }
    return View(Model);
}

我已经包括了下面的重量等级：

public partial class Weight
{
    public int Id { get; set; }
    public string UserId { get; set; }
    public Nullable<short> Stone { get; set; }
    public Nullable<short> Pound { get; set; }
    public Nullable<System.DateTime> Date { get; set; }
}

这里还有 WebApplication1 Entities 类，它将权重表声明为 Weights：

public partial class WebApplication1Entities : DbContext
{
    public WebApplication1Entities()
        : base("name=WebApplication1Entities")
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        throw new UnintentionalCodeFirstException();
    }

    public virtual DbSet<Weight> Weights { get; set; }
}

请解释一下需要修改什么，以及无论我尝试阅读、遵循和实施什么，我似乎都遗漏了一些东西。

任何帮助将非常感激 ：-）

我想说这是使用的一个很好的例子ViewModel这里。我会建议类似的东西 -

Create ViewModel以及两个班级的组成

public class AddWeightModel
{
    [Required]
    [DataType(DataType.Text)]
    [Display(Name = "Stone")]
    public Nullable<short> Stone { get; set; }

    [Required]
    [DataType(DataType.Text)]
    [Display(Name = "Pound")]
    public Nullable<short> Pound { get; set; }
}
....
public partial class Weight
{
    public int Id { get; set; }
    public string UserId { get; set; }
    public Nullable<short> Stone { get; set; }
    public Nullable<short> Pound { get; set; }
    public Nullable<System.DateTime> Date { get; set; }
}
.....
public class WeightViewModel
{
    public IList<AddWeightModel> AddWeightModel { get; set; }
    public Weight Weight { get; set; }
}

然后更改您的视图以接受视图模型 -

@model WeightViewModel

最后修改你的控制器以应对变化 -

public ActionResult RecordCard()
    {
        var UserId = User.Identity.GetUserId();
        var weightModel = from m in db.Weights where m.UserId == UserId select m;
        var viewModel = new WeightViewModel
        {
            Weight = weightModel,
            AddWeightModel = new List<AddWeightModel>(){}
        };
        return View(viewModel);
    }

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult RecordCard(WeightViewModel viewModel)
{
    Weight Model = viewModel.Weight;
    if (ModelState.IsValid)
    {
        using (WebApplication1Entities db = new WebApplication1Entities())
        {
            Weight weight = new Weight();
            weight.UserId = User.Identity.GetUserId();
            weight.Stone = Model.Stone;
            weight.Pound = Model.Pound;
            weight.Date = System.DateTime.Now;

            db.Weights.Add(Model);
            db.SaveChanges();
        }
    }
    return RedirectToAction("RecordCard");
}
