在 Edit() 视图上显示特定 Model.Id 的所有历史记录？
Show all history records for a particular Model.Id on Edit() View?
在我的库存跟踪程序中，我试图在有人打开 Edit() 视图时显示资产的所有历史记录。我的应用程序有 2 个相关模型 INV_Assets 和 INV_AssetsHistory:

现在，在我的 Edit() 视图中，我尝试了以下操作以获得我想要的：
尝试 1:
我使用 List 模板基于我的 INV_AssetsHistory 模型创建了一个 _AssetHistoryRecordsPartial 视图。这是当前使用我的 Shared Views 文件夹中的默认代码设置的。
@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，我收到以下标记上述代码行的 @Html.Partial()：
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
据我所知，错误是说我的 Partial 视图正在寻找模型的 IEnumerable<> 列表，而我正在传递我的主要 Model.Id （ INV_Assets) 我父视图中的 ID？
尝试 2:
因为我在我的 INV_Assets 模型 (public virtual ICollection<INV_AssetsHistory> AssetHistoryRecords { get; set; }) 上定义了一个 INV_AssetHistory 的集合，所以我想也许我可以使用这个集合作为 [=41= 中的模型定义]:
<div class="assetList">

}
catch (NullReferenceException ex)

return;

然而，这只会用显示 "There are no items to display" 的数据呈现我的列。我不理解这一点，因为我正在处理资产 1，并且我确保 INV_AssetsHistory 中有一条与 INV_AssetsHistory.AssetId == 1.
有关的记录
可能已经做过类似事情的人可以权衡一下如何解决这个问题吗？
更新:
根据 Murilo Amaru Gomes 的建议，我有以下几点：
INV_Assets - 编辑() 查看:
@{
Html.RenderAction("AssetHistoryGrid", "INV_Assets", new { id = Model.Id });
}
INV_Assets控制器:
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);
}
部分视图 - _AssetHistoryRecordsPartial:

当我尝试打开 Edit() 视图时，我收到以下信息：
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'.
此错误在 _Grid.cshtml 中的 @helper RenderGridBody() 下标记为 if (!Model.ItemsToDisplay.Any())，它是 GRIDMvc 包的一部分：
@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>
}
}
}
有人对此有想法吗？我以前在使用 GRIDMvc 时从来没有遇到过这样的错误。
您正在将 Model.Id 传递给 UserControl。你应该传递物品。模型中有它们吗？如果是这样你可以做@Html.Partial("_AssetHistoryRecordsPartial", Model.Items)，如果你不这样做你可以使用@{ Html.RenderAction("Action", "Some" , 新的 { id = Model.Id }); }, 在你的控制器中你需要
public class SomeController
{
public ActionResult Grid(int id)
{
var list = // Logic code to fill the items
return View("_AssetHistoryRecordsPartial", list);
}
}

然而，这只会用显示 "There are no items to display" 的数据呈现我的列。我不理解这一点，因为我正在处理资产 1，并且我确保 INV_AssetsHistory 中有一条与 INV_AssetsHistory.AssetId == 1.
可能已经做过类似事情的人可以权衡一下如何解决这个问题吗？
更新:
根据 Murilo Amaru Gomes 的建议，我有以下几点：
INV_Assets - 编辑() 查看:
@{
Html.RenderAction("AssetHistoryGrid", "INV_Assets", new { id = Model.Id });
}
INV_Assets控制器:
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);
}
部分视图 - _AssetHistoryRecordsPartial:
@model IEnumerable<InventoryTracker.Models.INV_AssetsHistory>
@using GridMvc.Html;
@using System.Collections.Generic;
<div class="assetList">
@try
{
@Html.Grid(Model).Columns(columns =>

当我尝试打开 Edit() 视图时，我收到以下信息：
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'.
此错误在 _Grid.cshtml 中的 @helper RenderGridBody() 下标记为 if (!Model.ItemsToDisplay.Any())，它是 GRIDMvc 包的一部分：
@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>
}
}
}
有人对此有想法吗？我以前在使用 GRIDMvc 时从来没有遇到过这样的错误。
您正在将 Model.Id 传递给 UserControl。你应该传递物品。模型中有它们吗？如果是这样你可以做@Html.Partial("_AssetHistoryRecordsPartial", Model.Items)，如果你不这样做你可以使用@{ Html.RenderAction("Action", "Some" , 新的 { id = Model.Id }); }, 在你的控制器中你需要
public class SomeController
{
public ActionResult Grid(int id)
{
var list = // Logic code to fill the items
return View("_AssetHistoryRecordsPartial", list);
}
}
