c# - Ajax.beginform 将空值发布到控制器

问题描述

我已经搜索了很多，但还没有找到答案。我有一个表格的部分视图：

@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>
}

此表单发布到我的控制器，但是当我查看控制器中的内容时，所有值都显示为空。

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表单和控制器，它可以处理其他一些可以完美运行的事情......

所以我有点迷茫，为什么返回的值只是空......

我的模型如果有兴趣：

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; }
    }

解决方案

模型绑定不起作用，DefaultModelBinder因为您在某些属性中使用internalset 访问器和get 访问器，如下所示：public

public string FullName { get; internal set; }

上述定义意味着：

  • 应用程序中的其他代码可以读取属性值
  • 只有在与您的应用程序相同的程序集中的代码才能向属性写入新值

由于DefaultModelBinder使用反射对属性的后端字段执行读取和写入值（您可以在其定义中看到），因此 get 和 set 访问器都必须设置public为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，以允许从 HTML 助手分配的属性值在视图中：

public string FullName { get; set; }
