错误的类型传入视图 - ASP.NET MVC 5

Question

我正在尝试创建适用于两种不同模型的视图.但是我一直在查看视图中传递的错误类型的错误:

传递到字典中的模型项的类型为'System.Data.Entity.DynamicProxies.ApplicationUser_D1BDF9065CBA1B8BC24F5E69ACC3CAB19A6C7FB8624B0C4435112D881B7C9CA2',但此字典需要类型为'StudentBookProject.ViewModel.UserPostWrapper'的模型项.

我已经创建了一个简单的包装类,所以我可以访问两个分离的类的所有属性,如下所示:

public class UserPostWrapper
{
    public ApplicationUser UserInfoObject { get; set; }
    public List<Post> PostInfoObject { get; set; }
}

这是抛出异常的视图:

@model StudentBookProject.ViewModel.UserPostWrapper

<script src="~/Scripts/jquery-1.10.2.js"></script>
<script src="~/Scripts/jquery-ui-1.11.2.js"></script>

@using (Html.BeginForm("Upload", "Posts", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <div class="jumbotron" style="height:300px">
        <div class="col-md-3">
            <img id="profilePhoto" src="data:image/png;base64,@Convert.ToBase64String(Model.UserInfoObject.ProfilePicture, 0, Model.UserInfoObject.ProfilePicture.Length)" width="150" />
        </div>
        <div id="dialog" style="display: none;">
            <img src="data:image/png;base64,@Convert.ToBase64String(Model.UserInfoObject.ProfilePicture, 0, Model.UserInfoObject.ProfilePicture.Length)">
        </div>
        <div class="col-md-push-5">
            @Html.Label(Model.UserInfoObject.Name + " " + Model.UserInfoObject.LastName, new { @class = "nameLabel" }) <br />
            @Html.Label(Model.UserInfoObject.DateOfBirth) <br />
            @Html.Label(Model.UserInfoObject.City)
        </div>
    </div>

    <div class="jumbotron" style="height:170px">
        <div class="col-lg-7">

            <textarea class="expand" rows="3" cols="20" placeholder="Share something with colleagues..."></textarea>
            <div class="icons">
                <a href="#" id="photoId" class="glyphicon glyphicon-camera" title="Add new photo"></a>
                <a href="#" id="fileId" class="glyphicon glyphicon-paperclip"></a>
                <button class="btn btn-sm btn-primary">Post</button>
            </div>
        </div>
        <input type="file" id="id_default_image" style="visibility: hidden" />
        <input type="file" id="id_default_file" style="visibility: hidden" />
        <div class="col-lg-5"></div>
    </div>
    <br />
    <br />
    <br />
}

这是呈现视图的操作:

[Authorize]
public ActionResult GetCurrentUser()
{
    var user = UserManager.FindById(User.Identity.GetUserId());
    return View(user);
}

我不确定我明白发生了什么.谁将错误的模型类型传递给视图,如果我已明确定义了我在该视图中使用的模型？有谁知道我在这里缺少什么？这种方法是否可行？

Answer 1

将您的操作更改为:

[Authorize]
public ActionResult GetCurrentUser()
{
    var user = UserManager.FindById(User.Identity.GetUserId());
    var model = new UserPostWrapper { UserInfoObject = user};
    return View(model);
}

正如我在评论中所说,你将一个不同的模型传递给你的观点.视图需要UserPostWrapper模型,但您传递的是ApplicationUser模型.
