Question

再次，在经过无聊的尝试解决这个恼人的问题之后，我又回到了这里。在我的控制器上执行了return RedirectToAction("Index", "Roles", model);操作后，我在MVC5应用程序中的视图中遇到了“对象移动到此处”。

我考虑过以下链接中的解决方案：

RedirectToAction and "Object moved to here" error
ASP.NET MVC Website: Object Moved to Here
https://forums.asp.net/t/1643235.aspx?+Object+moved+to+here+problem 但没有一个适用于我的问题。

之前有人将此标记为重复内容，请考虑以下方案：

但现在奇怪的是，点击“此处”链接后，它现在呈现我的视图 - 它有一个水平分屏，显示我的视图在顶部和在抛出Http错误代码的视图下方 - 在这种情况下，其错误代码500：内部服务器错误。

我收到http状态代码错误的原因是由于这个未解决的问题（许多人中的一个）：

Failed to load resource: Uncaught TypeError: $(...).select2 is not a function

但这就是现在的重点。

控制器：

        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Create([Bind(Include = "Name,Description")] ApplicationRole model)
        {
            try
            {
                if (ModelState.IsValid)
                {
                    var role = new ApplicationRole()
                    {
                        Name = model.Name,
                        Description = model.Description
                    };

                    var roleManager = new RoleManager<ApplicationRole>(new RoleStore<ApplicationRole>(db));
                    var result = await roleManager.CreateAsync(role);
                    if (result.Succeeded)
                    {
                        return RedirectToAction("Index", "Roles", model);
                    }
                    else
                    {
                        AddErrors(result);
                    }
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
            }
            // If we got this far, something failed, redisplay form
            return View(model);
        }

        //Below is my index method in my Roles controller which is the action that redirection needs to route to:

        [Route("/Roles")]
        public ActionResult Index()
        {
            if (TempData["StatusMessage"] != null)
            {
                ViewBag.StatusMessage = TempData["StatusMessage"].ToString();
            }
            else
            {
                ViewBag.StatusMessage = "";
            }

            var roles = db.Roles.ToList();
            return View("Index", roles);
        }



        //GET method to create view
        public ActionResult Create()
        {
          return View();
        }

查看：

@model IEnumerable<User_Manager_Interface.Models.ApplicationRole>

    Layout = "~/Views/Shared/_Layout.cshtml";
}


@if (ViewBag.StatusMessage != null)
{
    if (ViewBag.StatusMessage != "")
    {
        string tmp = ViewBag.StatusMessage;
        if (tmp.Contains("error"))
        {
            <div class="notification msgerror">
                <a class="close"></a>
                <p>@ViewBag.StatusMessage</p>

        }
        else
        {
            <div class="notification msgsuccess">
                <a class="close"></a>

“错误”控制器：

    public class ErrorController : Controller
    {
        //
        // GET: /Error/
        public ActionResult Index(int statusCode, Exception exception)
        {
            Response.StatusCode = statusCode;
            return View();          
        }
    }

“错误”查看：

@{
    ViewBag.Title = Response.StatusCode;
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2 style="visibility:hidden">@ViewBag.Title</h2>

<div class="errorWrapper">
    <h2>An internal server error @ViewBag.Title has occurred</h2>

请查看截图以获得更清晰的视觉效果：

更新根据@Munzer在下面的回答，我尝试更改我的索引操作方法以获取模型路由值，就像我在return语句中传递它一样。见下文：

        public async Task<ActionResult> Create(ApplicationRole model)
        {

                if (ModelState.IsValid)
                {
                    var role = new ApplicationRole()
                    {
                        Name = model.Name,
                        Description = model.Description
                    };

                    var roleManager = new RoleManager<ApplicationRole>(new RoleStore<ApplicationRole>(db));
                    var result = await roleManager.CreateAsync(role);
                    if (result.Succeeded)
                    {
                        //return RedirectToAction("Index", "Roles", model);
                        return RedirectToAction("SuccessfullyAddedNewRole", "Roles", model);
                    }
                    else
                    {
                        AddErrors(result);
                    }
                }


            // If we got this far, something failed, redisplay form
            return View(model);
        }



       public ActionResult SuccessfullyAddedNewRole(ApplicationRole model)
       {
          return View(model);
       }

但错误仍然存在。我已经尝试了我能想到的一切。

Answer 1

我认为错误就在这里

return RedirectToAction("Index", "Roles", model);

您正在传递路线值，但您的索引操作不接受任何，它会自动生成值，您可以简单地执行此操作

return RedirectToAction("Index", "Roles");，

并且您的索引将查询新模型，如果要传递模型，则需要相应地编辑索引操作，以接受角色模型。

Answer 2

解决方案可以在我的SO帖子上找到。修正了一切:-)

GET http://localhost/Roles/Create 500 (Internal Server Error)

对象已移至此处 - RedirectToAction
