在我的广告资源跟踪计划中，每当有人打开编辑（）视图时，我都会尝试显示资产的所有历史记录。我的申请有2个相关模型INV_Assets和INV_AssetsHistory：

INV_Assets ：

现在，在我的编辑（）视图中，我尝试了以下内容以获取我之后的内容：

尝试1 ：

我使用_AssetHistoryRecordsPartial模板基于INV_AssetsHistory模型创建了List视图。目前使用我的Shared Views文件夹中的默认代码进行设置。

@model IEnumerable<InventoryTracker.Models.INV_AssetsHistory>

<p>
    @Html.ActionLink("Create New", "Create")
</p>
<table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.Location.location_dept)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Manufacturer.manufacturer_description)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Model.model_description)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Status.status_description)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Type.type_description)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Vendor.vendor_name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.AssetId)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.ip_address)
        </th>

        ........

   </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.Location.location_dept)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Manufacturer.manufacturer_description)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Model.model_description)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Status.status_description)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Type.type_description)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Vendor.vendor_name)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.AssetId)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ip_address)
        </td>

        ................

    </tr>
}

</table>

编辑（）查看：

`@Html.Partial("_AssetHistoryRecordsPartial", Model.Id)`

当我运行应用程序并加载Edit（）视图时，我收到以下标记@Html.Partial()的上述代码行：

An exception of type 'System.InvalidOperationException' occurred in System.Web.Mvc.dll but was not handled in user code

Additional information: The model item passed into the dictionary is of type 'System.Int32', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1

我可以说，错误是我的Partial视图正在寻找模型的IEnumerable<>列表，而我正在传递我的主模型.Id（{{1} }）我的父视图中的ID？

尝试2 ：

由于我在INV_Assets模型（INV_AssetHistory）上定义了INV_Assets的集合，我想也许我可以将此集合用作GRIDMvc中的模型定义： 

public virtual ICollection<INV_AssetsHistory> AssetHistoryRecords { get; set; }

然而，这只会使我的列显示数据显示＆＃34;没有要显示的项目＆＃34;。由于我处理资产1并且我确保 <div class="assetList"> @try { @Html.Grid(Model.AssetHistoryRecords).Columns(columns => { columns.Add(o => o.Status.status_description).Titled("Status").RenderValueAs(o => o.Status.status_description).Sanitized(false).Encoded(false).Sortable(true).Filterable(true).SetWidth(20); columns.Add(o => o.Location.location_dept).Titled("Dept").RenderValueAs(o => o.Location.location_dept).SetWidth(20); columns.Add(o => o.Location.location_room).Titled("Room").RenderValueAs(o => o.Location.location_room).SetWidth(20); columns.Add(o => o.owner).Titled("Owner").RenderValueAs(o => o.owner).SetWidth(20); columns.Add(o => o.Type.type_description).Titled("Type").RenderValueAs(o => o.Type.type_description).SetWidth(20); columns.Add(o => o.Manufacturer.manufacturer_description).Titled("Manufacturer").RenderValueAs(o => o.Manufacturer.manufacturer_description).SetWidth(20); columns.Add(o => o.Model.model_description).Titled("Model").RenderValueAs(o => o.Model.model_description).SetWidth(20); columns.Add(o => o.Vendor.vendor_name).Titled("Vendor").RenderValueAs(o => o.Vendor.vendor_name).SetWidth(20); columns.Add(o => o.description).Titled("Desc").RenderValueAs(o => o.description).SetWidth(20); columns.Add(o => o.asset_tag_number).Titled("Asset Tag #").RenderValueAs(o => o.asset_tag_number).SetWidth(20); columns.Add(o => o.serial_number).Titled("Serial #").RenderValueAs(o => o.serial_number).SetWidth(20); columns.Add(o => o.ip_address).Titled("IP Addr").RenderValueAs(o => o.ip_address).SetWidth(20); columns.Add(o => o.mac_address).Titled("Mac Addr").RenderValueAs(o => o.mac_address).SetWidth(20); columns.Add(o => o.po_number).Titled("PO #").RenderValueAs(o => o.po_number).SetWidth(20); columns.Add(o => o.invoice_number).Titled("Inv. #").RenderValueAs(o => Convert.ToString(o.invoice_number)).SetWidth(20); columns.Add(o => o.cost).Titled("Cost").RenderValueAs(o => "$" + Convert.ToString(o.cost)).SetWidth(20); columns.Add(o => o.note).Titled("Note").RenderValueAs(o => o.note).SetWidth(20); columns.Add(o => o.acquired_date).Titled("Acq. Date").RenderValueAs(o => Convert.ToString(o.acquired_date)).SetWidth(20); columns.Add(o => o.disposed_date).Titled("Disp.

Date").RenderValueAs(o => Convert.ToString(o.created_date)).SetWidth(20); columns.Add(o => o.created_by).Titled("By").RenderValueAs(o => o.created_by).SetWidth(20); columns.Add(o => o.modified_date).Titled("Mod.

或许做过类似事情的人可以考虑如何解决这个问题吗？

更新：

使用Murilo Amaru Gomes的建议我有以下内容：

INV_Assets - 编辑（）视图：

INV_AssetsHistory.AssetId

INV_AssetsController ：

    @{
        Html.RenderAction("AssetHistoryGrid", "INV_Assets", new { id = Model.Id });
    }

部分视图 - _AssetHistoryRecordsPartial ：

    public IQueryable<INV_AssetsHistory> GetHistoryByAssetId(int assetId)
    {
        var records = db.INV_AssetsHistory.Where(x => x.AssetId == assetId);
        return records;
    }

    public ActionResult AssetHistoryGrid(int id)
    {
        var list = GetHistoryByAssetId(id);
        return View("_AssetHistoryRecordsPartial", list);
    }

当我尝试打开@model IEnumerable<InventoryTracker.Models.INV_AssetsHistory> @using GridMvc.Html; @using System.Collections.Generic; <div class="assetList"> @try { @Html.Grid(Model).Columns(columns => { columns.Add(o => o.Status.status_description).Titled("Status").RenderValueAs(o => o.Status.status_description).Sanitized(false).Encoded(false).Sortable(true).Filterable(true).SetWidth(20); columns.Add(o => o.Location.location_dept).Titled("Dept").RenderValueAs(o => o.Location.location_dept).SetWidth(20); columns.Add(o => o.Location.location_room).Titled("Room").RenderValueAs(o => o.Location.location_room).SetWidth(20); columns.Add(o => o.owner).Titled("Owner").RenderValueAs(o => o.owner).SetWidth(20); columns.Add(o => o.Type.type_description).Titled("Type").RenderValueAs(o => o.Type.type_description).SetWidth(20); columns.Add(o => o.Manufacturer.manufacturer_description).Titled("Manufacturer").RenderValueAs(o => o.Manufacturer.manufacturer_description).SetWidth(20); columns.Add(o => o.Model.model_description).Titled("Model").RenderValueAs(o => o.Model.model_description).SetWidth(20); columns.Add(o => o.Vendor.vendor_name).Titled("Vendor").RenderValueAs(o => o.Vendor.vendor_name).SetWidth(20); columns.Add(o => o.description).Titled("Desc").RenderValueAs(o => o.description).SetWidth(20); columns.Add(o => o.asset_tag_number).Titled("Asset Tag #").RenderValueAs(o => o.asset_tag_number).SetWidth(20); columns.Add(o => o.serial_number).Titled("Serial #").RenderValueAs(o => o.serial_number).SetWidth(20); columns.Add(o => o.ip_address).Titled("IP Addr").RenderValueAs(o => o.ip_address).SetWidth(20); columns.Add(o => o.mac_address).Titled("Mac Addr").RenderValueAs(o => o.mac_address).SetWidth(20); columns.Add(o => o.po_number).Titled("PO #").RenderValueAs(o => o.po_number).SetWidth(20); columns.Add(o => o.invoice_number).Titled("Inv. #").RenderValueAs(o => Convert.ToString(o.invoice_number)).SetWidth(20); columns.Add(o => o.cost).Titled("Cost").RenderValueAs(o => "$" + Convert.ToString(o.cost)).SetWidth(20); columns.Add(o => o.note).Titled("Note").RenderValueAs(o => o.note).SetWidth(20); columns.Add(o => o.acquired_date).Titled("Acq.

Edit()

在An exception of type 'System.NotSupportedException' occurred in EntityFramework.SqlServer.dll but was not handled in user code Additional information: The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'. if (!Model.ItemsToDisplay.Any())下@helper RenderGridBody()标记了_Grid.cshtml此错误，该@helper RenderGridBody() { if (!Model.ItemsToDisplay.Any()) { <tr class="grid-empty-text"> <td colspan="@Model.Columns.Count()"> @Model.EmptyGridText </td> </tr> } else { foreach (object item in Model.ItemsToDisplay) { <tr class="grid-row @Model.GetRowCssClasses(item)"> @foreach (IGridColumn column in Model.Columns) { @column.CellRenderer.Render(column, column.GetCell(item)) } </tr> } } } 是GRIDMvc包的一部分：

{{1}}

有人对此有何想法？在使用GRIDMvc之前，我从未遇到过这样的错误。

1 个答案:

答案 0 :(得分：1)

您正在将Model.Id传递给UserControl。你应该传递这些物品。你在模特中有他们吗？如果是这样你可以做@ Html.Partial（“_ AssetHistoryRecordsPartial”，Model.Items），如果你不能使用@ {Html.RenderAction（“Action”，“Some”，new {id = Model.Id}） ;在您的控制器中，您需要

public class SomeController
{
    public ActionResult Grid(int id)
    {
          var list = // Logic code to fill the items
          return View("_AssetHistoryRecordsPartial", list);
    }
 }
