Question

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

我的ViewModel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 - 我可以在VS中看到它。

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，我收到错误：

''System.Collections.Generic.IEnumerable'不包含'OfferVM'的定义，并且没有扩展方法'OfferVM'接受类型'System.Collections.Generic.IEnumerable'的第一个参数可以找到（你是吗？）缺少using指令或程序集引用？）'

我确信我错过了一些简单的事情 - 但是如何纠正我的问题会很好。

行@Html.EditorFor(Model => Model.OfferVM)错误，因为Model已经是IEnumeration。您可能在重构时弄乱了ViewModel？我建议为Create.cshtml设置一个容器ViewModel，因此您有一个类似IEnumerable<FGBS.ViewModels.OfferVM>类的模型，而不是模型CreateViewModel，它具有属性Offers，这是一个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：

开头

@model FGBS.ViewModels.CreateViewModel

在你的TH中，你会写出类似的东西：

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

等

EditorFor Template用于在表单上重复数据
