Question

我在ADO.NET实体数据模型中有两个链接模型。

AspNetUsers

    public partial class AspNetUsers
{
    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
    public AspNetUsers()
    {
        this.UserVacations = new HashSet<UserVacations>();
        this.UserSicknesses = new HashSet<UserSicknesses>();
    }
    public string Id { get; set; }
    public string Email { get; set; }
    public bool EmailConfirmed { get; set; }
    public string PasswordHash { get; set; }
    public string SecurityStamp { get; set; }
    public string PhoneNumber { get; set; }
    public bool PhoneNumberConfirmed { get; set; }
    public bool TwoFactorEnabled { get; set; }
    public Nullable<System.DateTime> LockoutEndDateUtc { get; set; }
    public bool LockoutEnabled { get; set; }
    public int AccessFailedCount { get; set; }
    public string UserName { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }

    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
    public virtual ICollection<UserVacations> UserVacations { get; set; }
    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
    public virtual ICollection<UserSicknesses> UserSicknesses { get; set; }
}

和UserSicknesses

    public partial class UserSicknesses
{
    public int SicknessId { get; set; }
    public string UserId { get; set; }
    public System.DateTime StartDate { get; set; }
    public System.DateTime EndDate { get; set; }

    public AspNetUsers AspNetUsers { get; set; }
}

在我的视图中，我想提交AspNetUsers的用户名和来自UserSicknesses的两个日期

    <div class="form-group row">
    @Html.LabelFor(model => model.AspNetUsers.UserName, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-xs-10">
        @Html.EditorFor(model => model.AspNetUsers.UserName, new { htmlAttributes = new { @class = "form-control"} })
        @Html.ValidationMessageFor(model => model.AspNetUsers.UserName, "", new { @class = "text-danger" })
    </div>
</div>
<div class="form-group row">
    @Html.LabelFor(model => model.StartDate, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-xs-10">
        @Html.EditorFor(model => model.StartDate, new { htmlAttributes = new { @class = "form-control", type = "date" } })
        @Html.ValidationMessageFor(model => model.StartDate, "", new { @class = "text-danger" })
    </div>
</div>
<div class="form-group row">
    @Html.LabelFor(model => model.EndDate, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-xs-10">
        @Html.EditorFor(model => model.EndDate, new { htmlAttributes = new { @class = "form-control", type = "date" } })
        @Html.ValidationMessageFor(model => model.EndDate, "", new { @class = "text-danger" })
    </div>
</div>

现在的问题是发布时userSicknesses.AspNetUsers为空，我无法接收用户名。 它们都由UserId连接，但我只想获取UserName和两个日期。

        [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "SicknessId,StartDate,EndDate,UserName")] UserSicknesses userSicknesses)
    {

        if (ModelState.IsValid && User.Identity.IsAuthenticated)
        {
            if (userSicknesses.StartDate > userSicknesses.EndDate)
            {
                ModelState.AddModelError("StartDate", "Das erste Datum kann nicht größer als das zweite sein!");
                return View(userSicknesses);
            }
            int sicId = 1;

            // Just for testing purposes but userSicknesses.AspNetUsers is Null
            string s = userSicknesses.AspNetUsers.UserName;

            if (db.UserSicknesses.Any())
            {
                sicId = (from a in db.UserSicknesses select a.SicknessId).Max() + 1;
            }
            userSicknesses.SicknessId = sicId;

            userSicknesses.UserId = db.AspNetUsers.Where(u => u.UserName == userSicknesses.AspNetUsers.UserName).Select(u => u).FirstOrDefault().ToString();

            db.UserSicknesses.Add(userSicknesses);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        return View(userSicknesses);
    }

在表单数据中Firefox告诉我： __RequestVerificationToken：KlY6b4CD41PaGoKJ ... AspNetUsers.UserName：管理员开始日期：2016年12月4日结束日期：2016年12月18日

我做错了什么？提前谢谢。

顺便说一句：这是我在asp.net的第一个项目，我很感激你的每一个建议！

检查以下代码以通过此结果：

$('#btnClick').on('click', function () {
var UserSicknesses= {
                    "AspNetUsers.UserName": $("#AspNetUsers_UserName").val(),
                    "StartDate ": $("#StartDate").html(),
                    "EndDate": $("#EndDate").val()

                };

                $.ajax({
                    url: '/ControllerName/Create',
                    type: "Post",
                    async: false,
                    data: JSON.stringify(UserSicknesses),
                    dataType: "html",
                    contentType: "application/json;charset=utf-8",
                    success: function (result) {
                        $("#gdiv").empty();
                        $("#gdiv").html(result);

                    }
                });
  });

我认为您可以使用包含两个模型的ViewModel并将其传递给视图。 check this answer，它与您的问题非常相似
