回发视图模型为空 [英] postback viewModel is null

问题描述

我试图寻找这个问题，但无法为它找到一个解决方案，请帮我

i try to search this problem, but could not find a solution for it, please help me:

我的视图模型：

namespace webShop.ViewModels.Home
{
    public class RegisterUserViewModel
    {
        public User User { get; set; }

        public UsersDetaile UsersDetaile { get; set; }

        public IEnumerable<state> state { get; set; }
    }
}

我的模型：

public partial class User
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Username { get; set; }
    public string Password { get; set; }
    public string Roles { get; set; }
    public byte Status { get; set; }

    public virtual UsersDetaile UsersDetaile { get; set; }
}

public partial class UsersDetaile
{
    public int userID { get; set; }
    public Nullable<System.DateTime> BirthDate { get; set; }
    public string Mobile { get; set; }
    public string Tell { get; set; }
    public bool Gender { get; set; }
    public byte city { get; set; }
    public byte state { get; set; }
    public string postCode { get; set; }
    public string address { get; set; }

    public virtual City City1 { get; set; }
    public virtual State State{ get; set; }
    public virtual User User { get; set; }
}

和我的控制器：

[HttpGet]
public ActionResult Register()
{ 
    OstanRepository stateRep = new OstanRepository();
    var model = new RegisterUserViewModel();
    model.state = stateRep.Select().ToList();
    return View(model);
}

[HttpPost]
public ActionResult Register(RegisterUserViewModel user)
{
   //My Code
}

和我注册查看

@model webShop.ViewModels.Home.RegisterUserViewModel

@using (Ajax.BeginForm("Register", "Home", new AjaxOptions { HttpMethod = "Post", Url = "/Home/Register" }))
{

  @Html.AntiForgeryToken()
  @Html.ValidationSummary(true)
  <h1 class="block-header">Register</h1>
      <div class="group">
          <label class="label">Name <span class="required">*</span></label>
          <div class="controls">
              @Html.TextBoxFor(p => p.User.Name, new { @class = "text" })
              @Html.ValidationMessageFor(p => p.User.Name)
          </div>
      </div>

    //....

  <div class="group">
        <label class="label">Address </label>
        <div class="controls">
            @Html.TextBoxFor(p => p.UsersDetaile.address, new { @class = "text" })
            @Html.ValidationMessageFor(p => p.UsersDetaile.address)
        </div>
  </div>

  <div class="form">
    <div class="group">
        <div class="controls">
             <button class="button">Submit</button>
        </div>
    </div>
  </div>
}

在preSS提交的用户和 usersDetaile 为 空的，我能做些什么？

after press submit user and usersDetaile is null, what can i do?

当然，如果我用这个acction，这是借机！

Of course, if i use this acction, it's worke!!!

public ActionResult Register(User user)
{
    //...
}

我不能找到一个解决方案，请帮我

推荐答案

绑定失败（ RegisterUserViewModel ）包含具有相同的名称（公众用户用户{获取;设置;}属性）

The binding fails because you POST method parameter is named user and your model (RegisterUserViewModel) contains property with the same name (public User User { get; set; })

您的方法签名更改为

[HttpPost]
public ActionResult Register(RegisterUserViewModel model)

和属性会被正确绑定。或者，您可以更改属性名称，但这就意味着更新您的看法code

and the properties will be correctly bound. Alternatively, you can change the property name but this would mean updating your view code

`public User Person { get; set; }`
