在项目列表中发布列表 - 无法检索控制器中的项目

标签： asp.net-mvc model-binding

我知道之前已经问过这个问题，但是我已经按照这样的其他线程的答案，但仍然无法解决我的问题。

所以我所拥有的是一个包含列表的表单，其中包含另一个列表，我想在我的帖子操作控制器中检索所有这些项目，以便我可以更新控制器中的权限。但是我目前无法在我的帖子中检索我的项目而且我不知道为什么。

查看：

@using (Html.BeginForm())
                {
                    <ul class="nav well-tabs well-tabs-inverse margin-bottom">
                        @for (int counter = 0; Model.Count > counter; counter++)
                        {
                            <li @if (counter == 0) { @Html.Raw("class='active'")  }><a href="@Html.Raw("#tab" + counter)" data-toggle="tab">@Model[counter].Permissions.RoleName</a></li>
                        }
                    </ul>
                    <!-- Rechten Content -->
                    <div class="tab-content border-none padding-none">

                        @for (int counter = 0; Model.Count > counter; counter++)
                        {
                            <div @Html.Raw(string.Format("id=tab{0}", counter)) class="tab-pane @if (counter == 0)
                                                                                                {
                                                                                                    @Html.Raw("active")
                                                                                                }">
                                <table class="table table-widget table-striped">
                                    <thead>
                                        <tr>
                                            <th>Recht</th>
                                            <th>Machtiging</th>
                                        </tr>
                                    </thead>
                                    <tbody>
                                        <!-- Get all the updated permissions -->
                                        @for (int counter2 = 0; Model[counter].Permissions.Rights.Count() > counter2; counter2++)
                                        {
                                             <tr>
                                                <td>@Model[counter].Permissions.Rights[counter2].RightName</td>
                                                <td>@Html.CheckBoxFor(m=> m[counter].Items[counter2].Selected)
                                                @Html.HiddenFor(m => m[counter].Items[counter2].RightId)
                                                @Html.HiddenFor(m => m[counter].Items[counter2].RoleName)
                                                </td>
                                            </tr>
                                        }
                                    </tbody>
                                </table>
                            </div>
                        }
                        <input type="submit" value="Gegevens opslaan" css="btn btn-info" />
                    </div>

                }

型号：

  public class ViewRolePermissionsModel
{
    public Permissions Permissions { get; set; }
    public List<Items> Items;
}

// Sub class
public class Permissions
{
    public string RoleName { get; set; }
    public List<RightModel> Rights { get; set; }
}

// Sub class
public class RightModel
{
    public int RightId { get; set; }
    public string RightName { get; set; }
}

// Sub class
public class Items
{
    public int RightId { get; set; }
    public string RoleName { get; set; }
    public bool Selected { get; set; }
}

在我看来，结果如下： End result html

这是我的控制器生成的内容以及我希望在后期操作中获得的内容： Controller generated code

一些示例代码拼凑在一起。首先是控制器方法：

public ActionResult ProcessModel()
{
    ViewRolePermissionsModel newResponse = ProcessRoles(Request.Form);
}

然后将其解析为模型的方法

private ViewRolePermissionsModel ProcessRoles(System.Collections.Specialized.NameValueCollection requestForm)
{
    ViewRolePermissionsModel viewRolePermissionsModel = new ViewRolePermissionsModel();

    String[] allKeys = requestForm.AllKeys;

    foreach (String localKey in allKeys)
    {
        itemValue = requestForm.GetValues(localKey).FirstOrDefault();
        //  depending on the localKey either use this to add the value to the model or to build a list to be added later
    }
}
