Question

我整天都在挣扎这是我有史以来的第一篇文章，如果很难理解或格式不正确，敬请见谅

我正在使用ViewModel在一个视图中合并两个实体。对于第一个实体，我使用textboxfor和lablefor html帮助器来收集发布请求的数据。对于第二实体Im，使用下拉列表，该下拉列表是在另一视图中输入的一组地址对象的选择列表。我在地址类上使用了数据注释，以使所有字段必填。一旦条目通过验证并通过添加地址视图保存到我的数据库中。当我尝试使用视图模型选择它时，我收到验证异常，该异常指示我的地址条目中必填字段

如果我删除了对地址类的验证，那似乎可行

我的控制器

public ActionResult AddMember()
    {
        var ViewMember = new MemberViewModel(); 
            ViewMember.AddressList = new SelectList(_context.Addresses, "Id", "streetName");



        return View(ViewMember);
    }




    [HttpPost]
    public ActionResult AddMember(MemberViewModel Entry)
    {
        var entry = new Member();
        entry = Entry.member;

        entry.Address = new Address() {Id= Entry.addressId };

        if (ModelState.IsValid)
        {

            repository.AddMember(entry, _context);

            TempData["message"] = "Your Member was added";


            return RedirectToAction("Members", new { id = entry.Id });
        }
        return View();
    }

我的观点

@model  AdesinaWebApp.ViewModels.MemberViewModel
@{
  ViewBag.Title = "AddMember";
  Layout = "~/Views/Shared/_Layout.cshtml";
}

 <h2>AddMember</h2>

@using (Html.BeginForm()){


@Html.LabelFor(fn => fn.member.Name)<br>
@Html.TextBoxFor(fn => fn.member.Name)<br /><br />

@Html.LabelFor(fn => fn.member.LastName)<br>
@Html.TextBoxFor(fn => fn.member.LastName)<br />

@*@Html.LabelFor(fn => fn.address.DoorNumber)<br>
@Html.TextBoxFor(fn => fn.address.DoorNumber)<br /><br />

@Html.LabelFor(fn => fn.address.streetName)<br>
@Html.TextBoxFor(fn => fn.address.streetName)<br /><br />

@Html.LabelFor(fn => fn.address.PostCode)<br>
@Html.TextBoxFor(fn => fn.address.PostCode)<br /><br />*@



@Html.LabelFor(m=>m.addressId)
@Html.DropDownListFor(m=>m.addressId,Model.AddressList,"please select your address")



<button type="submit">Submit</button>

 }

我的视图模型

 public class MemberViewModel


{

    public int addressId { get; set; }

    public Address address { get; set; }

    public Member member { get; set; } = new Member();

   public SelectList AddressList { get; set; }



}

我的地址分类

public class Address
{
    [Key]
    public int Id { get; set; }
    [Required(ErrorMessage = "Please enter a Door Number")]
    public int DoorNumber { get; set; }
    [Required(ErrorMessage = "Please enter a Street Name.")]
    public string streetName { get; set; }
    [Required(ErrorMessage = "Please enter a Post Code.")]
    public string PostCode { get; set; }

    public ICollection<Member> Members { get; set; }
}


     public class Member
   {
    [Key]
    [Required]
    public int Id { get; set; }
    [Required]
    public string Name { get; set; }
    [Required]
    public string LastName { get; set; }


    public Address Address { get; set; }
    }

非常感谢您的帮助
