用于在窗体上重复数据的模板的编辑器
本文关键字:编辑器 数据 窗体 用于 | 更新日期: 2023-09-27 18:21:02
我正在尝试为重复类(Offer)设置EditorTemplate-但是,我很难让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中看到它被填充。
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>
然而,当我运行代码时,我会得到错误:
"System.Collections.Generic.IEnumerable"不包含"OfferVM"的定义,也找不到接受类型为"System.Collections.cGeneric.IEnumerable"的第一个参数的扩展方法"OfferVM"(是否缺少using指令或程序集引用?)"
我肯定我错过了一些简单的东西,但任何关于如何纠正我的问题的建议都会很棒。
行@Html.EditorFor(Model => Model.OfferVM)
是错误的,因为Model
已经是IEnumeration。你可能在重构时把ViewModel搞砸了?我建议为Create.cshtml
提供一个容器ViewModel,这样就可以使用一个类似Model的CreateViewModel
类来代替模型IEnumerable<FGBS.ViewModels.OfferVM>
,该类然后具有属性Offers
,即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,你会写一些类似的东西:
@Html.DisplayNameFor(x => x.Header.RoomTypeId)
等等。
