无法将数据从模型传递到局部视图

Question

问题是我无法将数据从模型传递到 PartialView。这是我的做法。

我的PartialsController.cs

public PartialViewResult _GridView()
    {

        var currentUser = UserManager.FindById(User.Identity.GetUserId());
        var ranks = ApplicationDbContext.Ranks.ToList();

        foreach (var item in ranks)
        {
            if (currentUser.ReputationPoints > item.ReputationPoints && currentUser.ReputationPoints < item.PointsToAdvance)
            {
                currentUser.UserRankId = item.Id;
                ApplicationDbContext.Entry(currentUser).State = EntityState.Modified;
                ApplicationDbContext.SaveChanges();
            }
        }
        var Rank = ApplicationDbContext.Ranks.SingleOrDefault(c => c.Id == currentUser.UserRankId);



        return PartialView(currentUser);
    }

我的局部视图名为 _GridView.cshtml

@model Destiny.Models.ApplicationUser
@using Microsoft.AspNet.Identity
@if (Request.IsAuthenticated)
{
using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))
{
    @Html.AntiForgeryToken()

    <ul class="nav navbar-nav navbar-right">
        <li>
            @Html.ActionLink("Zalogowano jako " + Model.CurrentUser.Gamertag, "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" })
        </li>
        <li><a href="javascript:document.getElementById('logoutForm').submit()">Wyloguj</a></li>
    </ul>
}
  }
  else
          {
<ul class="nav navbar-nav navbar-right">
    <li>@Html.ActionLink("Zarejestruj", "Register", "Account",routeValues: null, htmlAttributes: new { id = "registerLink" })</li>
    <li>@Html.ActionLink("Zaloguj", "Login", "Account", routeValues: null, htmlAttributes: new { id = "loginLink" })</li>
</ul>
 }

partialView 需要另一个 ViewModel（顺便说一句，它用于我的 Home/Index），事实是我 100% 确定我在传递数据时做错了什么，但我不知道它是什么。这是我第一次弄乱部分视图。

使用

   @Html.RenderAction

而不是

   @Html.Partial( in the layout –

这边

 @{Html.RenderAction("_GridView");}
