Ajax.beginform将空值发布到控制器

Question

我已经搜索了很多但还没有找到答案..我有一个表格的局部视图：

@model PetDate.Models.ProfileDataModel

@using (Ajax.BeginForm("UpdateProfileInfo", "Profile", new AjaxOptions { HttpMethod = "Post", OnFailure = "", OnSuccess = "" }))
{
    <div class="form-group">
        @Html.LabelFor(x => x.FullName, new { @class = "text-info" })
        @Html.TextBoxFor(x => x.FullName, new { @class = "form-control" })
    </div>
    <div class="form-group">
        @Html.LabelFor(x => x.Email, new { @class = "text-info" })
        @Html.TextBoxFor(x => x.Email, new { @class = "form-control", @type = "email" })
    </div>
    <div class="form-group">
        @Html.LabelFor(x => x.BirthDay, new { @class = "text-info" })
        @Html.TextBoxFor(x => x.BirthDay, new { @class = "form-control", @type = "datetime" })
    </div>
    <div class="form-group">
        @Html.LabelFor(x => x.Username, new { @class = "text-info" })
        @Html.TextBoxFor(x => x.Username, new { @class = "form-control" })
    </div>
    <div class="form-group">
        @Html.LabelFor(x => x.AddressText, new { @class = "text-info" })
        @Html.TextBoxFor(x => x.AddressText, new { @class = "form-control", @id = "adresse" })


        @Html.HiddenFor(x => x.Postal, new { @id = "postalAddress" })
        @Html.HiddenFor(x => x.Street, new { @id = "streetAddress" })
        @Html.HiddenFor(x => x.HouseNumber, new { @id = "houseNumberAddress" })
        @Html.HiddenFor(x => x.story, new { @id = "storyAddress" })
        @Html.HiddenFor(x => x.roomPlacement, new { @id = "roomPlacementAddress" })

    </div>
    <div class="form-group">
        @Html.LabelFor(x => x.Description, new { @class = "text-info" })
        @Html.TextAreaFor(x => x.Description, new { @class = "initTinyMCE" })
    </div>
    <div class="form-group">
        <button type="submit" class="btn btn-outline-warning btn-lg" >Opdatér information</button>
    </div>
}

这个表单发布到我的控制器，但当我看到我在控制器中得到的内容时，所有值都显示为null。

我的控制器：

namespace PetDate.Controllers
{
    public class ProfileController : MasterController
    {

        [ValidateInput(false)]
        [HttpPost]
        public ActionResult UpdateProfileInfo(ProfileDataModel data)
        {
            int ownerID = Convert.ToInt32(Session["userID"]);
            if (ModelState.IsValid)
            {
                using (var context = new ModelContainer())
                {
                    var ownerProfile = context.Owners.Where(x => x.ID == ownerID).FirstOrDefault();
                    var ownerLogin = context.Logins.Where(x => x.Owner_ID == ownerID).FirstOrDefault();

                    Address ownerAddress = null;

                    if (data.story != 0 && data.roomPlacement != string.Empty)
                    {
                        ownerAddress = context.Addresses.Where(x => x.Postal == data.Postal && x.Street == data.Street && x.Housenumber == Convert.ToInt32(data.HouseNumber) && x.Story == Convert.ToInt32(data.story) && x.Door == data.roomPlacement).FirstOrDefault();
                    }
                    else { 
                        ownerAddress = context.Addresses.Where(x => x.Postal == data.Postal && x.Street == data.Street && x.Housenumber == Convert.ToInt32(data.HouseNumber)).FirstOrDefault();
                    }


                    if (ownerProfile != null && ownerLogin != null)
                    {
                        // update content.
                        ownerProfile.FullName = data.FullName;
                        ownerProfile.Email = data.Email;
                        ownerProfile.Birthday = data.BirthDay;
                        ownerProfile.Description = data.Description;
                        ownerProfile.ProfilePicture = data.ProfilePicture;
                        ownerLogin.UserName = data.Username;

                        if (ownerAddress != null)
                        {   // already created the address, just get the ID
                            ownerProfile.Address_FK = ownerAddress.ID;

                        }
                        else
                        {   // has not been created before, create new one.

                            var obj = new Address()
                            {
                                Postal = data.Postal,
                                Street = data.Street,
                                Housenumber = Convert.ToInt32(data.HouseNumber),
                                Story = data.story,
                                Door = data.roomPlacement != string.Empty ? data.roomPlacement : ""
                            };

                        }


                        context.SaveChanges();
                        return new HttpStatusCodeResult(200, "ok");
                    }
                    else
                    {
                        return new HttpStatusCodeResult(400, "failure");
                    }
                }
            }
            else
            {
                return new HttpStatusCodeResult(400, "failure");
            }
        }
    }
}

变量Data具有空值。我有一个几乎相似的形式，和控制器，处理一些完美的工作...

所以我有点迷失为什么返回的值只是null ...

我感兴趣的模型：

public class ProfileDataModel
    {
        [Required]
        public string FullName { get; internal set; }
        [Required]
        public DateTime? BirthDay { get; internal set; }
        [Required]
        public string Description { get; internal set; }
        [Required]
        public string Email { get; internal set; }
        [Required]
        public string AddressText { get; internal set; }
        [Required]
        public string Postal { get; set; }
        [Required]
        public string Street { get; set; }
        [Required]
        public int HouseNumber { get; set; }
        public int story { get; set; }
        public string roomPlacement { get; set; }
        [Required]
        public string ProfilePicture { get; internal set; }
        [Required]
        public string Username { get; internal set; }
        public string Password { get; set; }
    }

Answer 1

由于您的setter标记为internal，因此模型绑定器无法设置属性。

改变

 public string FullName { get; internal set; }

至

 public string FullName { get; set; }

应该解决你的问题

Answer 2

模型绑定不适用于DefaultModelBinder，因为你在一些属性中使用internal set accessor和public get accessor：

public string FullName { get; internal set; }

以上定义是指：

• 您的应用程序中的其他代码可以读取属性值
• 只有与您的应用程序相同的程序集中的代码可能会向该属性写入新值

由于DefaultModelBinder使用反射在属性的后端字段中执行读取和写入值（您可以在its definition中看到），因此必须将get和set访问器设置为public以启用具有自动属性的双向模型绑定。

因此，viewmodel类中的所有属性都必须将get和set访问器定义为public，以便从视图中的HTML帮助程序中分配属性值：

public string FullName { get; set; }
