如何在 ASP.NET MVC 中绑定 HttpPost 上的嵌套对象 [英] How to bind nested objects on HttpPost in ASP.NET MVC

问题描述

我已经开始实施这个解决方案绑定属性包含和排除具有复杂类型嵌套对象的属性

I have started to implement this solution bind attribute include and exclude property with complex type nested objects

但它根本不起作用.

同样的问题在这里在 HttpPost 上使用 MVC3 绑定嵌套模型

但没有具体的答案.

型号

[Bind(Include = "FirstName,MiddleName,LastName,Position,TruckTypeID,Direction,Organization,Objective,TimeStart,TimeEnd")]
public partial class UserRequestRegisterModel
{
    [DisplayName("Имя")]
    [Required]
    public string FirstName { get; set; }

    [DisplayName("Фамилия")]
    [Required]
    public string MiddleName { get; set; }

    [DisplayName("Отчество")]
    [Required]
    public string LastName { get; set; }

    [DisplayName("Должность")]
    [Required]
    public string Position { get; set; }

    [DisplayName("Тип транспорта")]
    [Required]
    public System.Guid TruckTypeID { get; set; }

    [DisplayName("Направление")]
    [Required]
    public string Direction { get; set; }

    [DisplayName("Организация")]
    [Required]
    public string Organization { get; set; }

    [DisplayName("Цель")]
    [Required]
    public string Objective { get; set; }

    [DisplayName("Время убытия")]
    [Required]
    // [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy  HH:mm}", ApplyFormatInEditMode = true)]
    public System.DateTime TimeStart { get; set; }

    [DisplayName("Время прибытия")]
    [Required]
    // [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy HH:mm}", ApplyFormatInEditMode = true)]
    public Nullable<System.DateTime> TimeEnd { get; set; }        
}


[Bind(Include = "UserRequest")]
public partial class RequestUserModel
{
    public List<UserRequestViewItem> UserRequestViewItems { get; set; }
    public UserRequestRegisterModel UserRequest { get; set; }

    public RequestUserModel()
    {
        UserRequestViewItems = new List<UserRequestViewItem>();
        UserRequest = new UserRequestRegisterModel();
    }
}

控制器

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Index([Bind(Include = "FirstName,MiddleName,LastName,Position,TruckTypeID,Direction,Organization,Objective,TimeStart,TimeEnd")] RequestUserModel userRequest)
//public ActionResult Index(RequestUserModel userRequest)
{
    // !  userRequest.UserRequest is empty  !
    //...
}

推荐答案

经过 30 分钟的自由泳实验后，我终于让它发挥作用了.

After 30 minutes of freestyle experimenting I finally get it working.

所以，伙计们，解决方案如下

So, guys, solution is following

模型

 [Bind(Include = "FirstName,MiddleName,LastName,Position,TruckTypeID,Direction,Organization,Objective,TimeStart,TimeEnd")]
    public partial class UserRequestRegisterModel
    {
        [DisplayName("Имя")]
        [Required]
        public string FirstName { get; set; }

        [DisplayName("Фамилия")]
        [Required]
        public string MiddleName { get; set; }

        [DisplayName("Отчество")]
        [Required]
        public string LastName { get; set; }

        [DisplayName("Должность")]
        [Required]
        public string Position { get; set; }

        [DisplayName("Тип транспорта")]
        [Required]
        public System.Guid TruckTypeID { get; set; }

        [DisplayName("Направление")]
        [Required]
        public string Direction { get; set; }

        [DisplayName("Организация")]
        [Required]
        public string Organization { get; set; }

        [DisplayName("Цель")]
        [Required]
        public string Objective { get; set; }

        [DisplayName("Время убытия")]
        [Required]
        // [DataType(DataType.Date)]
        [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy  HH:mm}", ApplyFormatInEditMode = true)]
        public System.DateTime TimeStart { get; set; }

        [DisplayName("Время прибытия")]
        [Required]
        // [DataType(DataType.Date)]
        [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy HH:mm}", ApplyFormatInEditMode = true)]
        public Nullable<System.DateTime> TimeEnd { get; set; }        
    }


public partial class RequestUserModel
    {
        public List<UserRequestViewItem> UserRequestViewItems { get; set; }
        public UserRequestRegisterModel UserRequest { get; set; }

        public RequestUserModel()
        {
            UserRequestViewItems = new List<UserRequestViewItem>();
            UserRequest = new UserRequestRegisterModel();
        }
    }

HTML

@model TransportRequests.Models.RequestUserModel
...

@using (Html.BeginForm("CreateUserRequest", null, FormMethod.Post, null))
{
   @Html.EditorFor(model => model.UserRequest.FirstName, new { htmlAttributes = new { @class = "form-control", @style = "width:200px" } })
}

控制器

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult CreateUserRequest([Bind(Include = "UserRequest")] RequestUserModel model)
{
     // and here all properties has inputed values... YEAH!!!  :)

     var firstName = model.UserRequest.FirstName;

     return RedirectToAction("Index");
}
