我正在尝试为重复类(优惠)设置 EditorTemplate - 但是,我无法让 EditorTemplate 正常工作:

我的视图模型是:

    public class OfferVM
    {
    public int RoomTypeId { get; set; }
    public int PropertyId { get; set; }
    public string RoomTypeName { get; set; }
    public string Layout { get; set; }
    public decimal RoomRate { get; set; }
    public string Inclusions { get; set; }
    public string Property { get; set; }
    public bool IncludeInOffer { get; set; }
    }

我的控制器获取代码是:

    //
    // GET: /Offer/Create
    public ActionResult Create()
    {
        var roomtypes = db.RoomTypes.Include(r => r.Property).ToList();
        IList<OfferVM> offerVM = Mapper.Map<IList<RoomType>, IList<OfferVM>>(roomtypes);
        return View(offerVM);
    }

控制器工作正常 - 我可以看到它填充在 VS 中。

我的 Create.cshtml 代码是:

@model IEnumerable<FGBS.ViewModels.OfferVM>
@{
ViewBag.Title = "Create";
}

<h2>Create</h2>

@using (Html.Bootstrap().Begin(new Form().Type(FormType.Horizontal))) {
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)

<fieldset>
    <legend></legend>


<table>
<tr>
    <th>
        @Html.DisplayNameFor(model => model.RoomTypeId)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.PropertyId)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.RoomTypeName)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.Layout)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.RoomRate)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.Inclusions)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.Property)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.IncludeInOffer)
    </th>
    <th></th>
    </tr>

    @Html.EditorFor(Model => Model.OfferVM)

    </table>

然后在我的 Views/Home/EditorTemplates 文件夹中我有我的 OfferVM.cshtml 文件:

@model FGBS.ViewModels.OfferVM

@{
    Layout = null;
}
  <tr>
    <td>
        @Html.EditorFor(model => model.RoomTypeId)
        @Html.ValidationMessageFor(model => model.RoomTypeId)
    </td>


    <td>
        @Html.EditorFor(model => model.PropertyId)
        @Html.ValidationMessageFor(model => model.PropertyId)
    </td>


    <td>
        @Html.EditorFor(model => model.RoomTypeName)
        @Html.ValidationMessageFor(model => model.RoomTypeName)
    </td>


    <td>
        @Html.EditorFor(model => model.Layout)
        @Html.ValidationMessageFor(model => model.Layout)
    </td>


    <td>
        @Html.EditorFor(model => model.RoomRate)
        @Html.ValidationMessageFor(model => model.RoomRate)
    </td>


    <td>
        @Html.EditorFor(model => model.Inclusions)
        @Html.ValidationMessageFor(model => model.Inclusions)
    </td>


    <td>
        @Html.EditorFor(model => model.Property)
        @Html.ValidationMessageFor(model => model.Property)
    </td>


    <td>
        @Html.EditorFor(model => model.IncludeInOffer)
        @Html.ValidationMessageFor(model => model.IncludeInOffer)
  </td>

    </tr>

但是,当我运行代码时,出现错误:

''System.Collections.Generic.IEnumerable' 不包含'OfferVM' 的定义,并且找不到接受'System.Collections.Generic.IEnumerable' 类型的第一个参数的扩展方法'OfferVM'(您是否缺少使用指令还是程序集引用?)'

我确定我错过了一些简单的事情——但是任何关于如何纠正我的问题的建议都会很棒。

该行@Html.EditorFor(Model => Model.OfferVM)是错误的,因为Model已经是 IEnumeration。您可能在重构时弄乱了 ViewModel?我建议有一个容器 ViewModel Create.cshtml,所以IEnumerable<FGBS.ViewModels.OfferVM>你有一个 Model类,而不是 ModelCreateViewModel类,然后有一个属性Offers,它是一个IList<OfferVM>.

您的型号代码:

public class OfferVM
{
    ....
}

public class CreateViewModel {
    public IList<OfferVM> Offers { get; set; }
    public OfferVM Header {
        get {
            return Offers.FirstOrDefault();
        }
    }
}

您的控制器代码:

var vm = new CreateViewModel();
vm.Offers = Mapper.Map<IList<RoomType>, IList<OfferVM>>(roomtypes);
return View(vm);

您的 Create.cshtml 以:

@model FGBS.ViewModels.CreateViewModel

在您的 TH 中,您将编写如下内容:

@Html.DisplayNameFor(x => x.Header.RoomTypeId)

等等
