Question

我试图查看两个单独的表，但在同一视图中它们之间没有关系。这个想法是创建一个帐户并将其添加到帐户表中，并添加多个吊球并将其添加到吊球表中。所以我为每个视图制作了两个局部视图。我制作了一个ViewModel，它有一个帐户实例和lob列表。问题出在主视图中，局部模型返回null。我不知道为什么有任何想法吗？感谢您的帮助。

@model Manage_account.Models.AccountVM

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>


@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
<div class="form-horizontal">
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })

        <div class="form-group">
            <div>
                @{Html.RenderPartial("~/Views/AccountOrOU/PartialViews/_Account.cshtml", Model);}
            </div>
            <div>
                @{Html.RenderPartial("~/Views/AccountOrOU/PartialViews/_Lob.cshtml", Model);}
            </div>
        </div>

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" />
            </div>
        </div>

    </div>

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

局部视图：

@model Manage_account.Models.AccountOrOU


@using (Html.BeginForm())
{
    <div class="form-horizontal" id="ViewData">
        <h4>AccountOrOU</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })

        <div class="form-group">

            <div class="col-md-10">
                @Html.HiddenFor(model => model.AccountOrOUID, new { htmlAttributes = new { @class = "form-control" } })

            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.AccountOrOUName, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.AccountOrOUName, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.AccountOrOUName, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.DepartmentID, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.DepartmentID, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.DepartmentID, "", new { @class = "text-danger" })
            </div>
        </div>
    </div>

}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

型号：

 public class AccountVM
    {
        public AccountOrOU AccountOrOU { get; set; }
        public List<Lob> lobs { get; set; }

    }

控制器：

 public ActionResult Create()
        {

            return View();
        }


        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Create(AccountVM vM)
        {if (vM != null)
            {
                var myAccount = db.AccountOrOUs.ToList();
                foreach (var acc in myAccount)
                {
                    acc.AccountOrOUID= vM.AccountOrOU.AccountOrOUID ;
                    acc.AccountOrOUName=vM.AccountOrOU.AccountOrOUName ;
                    acc.DepartmentID=vM.AccountOrOU.DepartmentID ;
                    db.AccountOrOUs.Add(acc);
                }
                db.SaveChanges();
            }


            return View("Index");
        }

Answer 1

我刚刚删除了部分ViewData.Model.AccountOrOU并添加了Model，它起作用了?。但老实说，我不知道这里的区别。第一个我曾经使用过并且正在工作。我不知道为什么不参与这个项目？

部分视图模型从主视图返回null
