所以,我有一个控制器/视图/视图模型的问题。它与我认为的this issue类似。基本上,我有一个viewmodel,我发送到我的控制器的视图。在将整个混乱发送回控制器后期操作之前,有些项目会显示,然后是一些其他字段供用户操作。当我在帖子中收到数据时,所有的viewmodel都是空的。
所以,不用多说了,这里有一些代码可以看:
视图模型:
public class ASideReceivingViewModel
{
public PurchaseOrderLine poLine;
public ReceivingItem receivingItem;
public Dictionary<string, string> TankerOrRailcarOptions { get; set; }
public ASideReceivingViewModel()
{
TankerOrRailcarOptions = new Dictionary<string, string>();
TankerOrRailcarOptions.Add("R", "Railcar");
TankerOrRailcarOptions.Add("T", "Tanker");
}
}
控制器操作:
public ActionResult Receive(string strOrdNo, short? shtLineNo)
{
//if there isn't a selected po line, then shoot them back to the first page
if (strOrdNo == null || !shtLineNo.HasValue) return RedirectToAction("Index");
PurchaseOrderService poService = new PurchaseOrderService();
ReceivingItemService s = new ReceivingItemService(p);
ASideReceivingViewModel vm = new ASideReceivingViewModel();
vm.poLine = poService.GetOpenPurchaseOrderLines().Where(po => po.Ord_no == strOrdNo &&
po.Line_no == shtLineNo).FirstOrDefault();
if (vm.poLine == null) return RedirectToAction("Index");
vm.receivingItem = s.CreateNewReceivingItem(vm.poLine);
return View(vm);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Receive(ASideReceivingViewModel mytestvm)
{
if (ModelState.IsValid && mytestvm.receivingItem != null)
{
ReceivingItemService s = new ReceivingItemService(p);
s.Update(mytestvm.receivingItem);
return RedirectToAction("Index");
}
return View(mytestvm);
}
查看:
@model FSIApps.Presentation.Models.ASideReceivingViewModel
<div class="row">
@{Html.RenderPartial("POLineDetails", Model.poLine);}
</div>
@using (Html.BeginForm("Receive", "Receiving", FormMethod.Post))
{
@Html.HiddenFor(model => model.receivingItem.Id)
<div class="row">
<div class="col-md-8 col-md-offset-2">
<div class="row">

<div class="col-md-6">

<label for="receivingItem_">Tanker or Railcar</label>
@Html.DropDownListFor(m => m.receivingItem.Tanker_or_railcar, new SelectList(Model.TankerOrRailcarOptions, "Key", "Value", Model.receivingItem.Tanker_or_railcar), new { @class = "form-control" })
</div>
</div>
</div>
<div class="row">
<div class="col-md-6">
<div class="form-group">

@Html.TextBoxFor(model => model.receivingItem.Railcar_number, new { @class = "form-control" })
</div>
</div>
<div class="col-md-6">
<div class="form-group">
<label for="receivingItem_Manifest_number">Manifest Number</label>
@Html.TextBoxFor(model => model.receivingItem.Manifest_number, new { @class = "form-control" })
</div>
</div>
</div>
<div class="row">
<div class="col-md-6">
<div class="form-group">
<input type="submit" value="Save" class="btn btn-success" />
</div>
</div>
</div>
</div>
</div>
}
我不一定关心我发送到局部视图的数据,但是当我回发常规表单时,我在ViewModel中没有设置任何内容。在另一篇文章中,他们讨论了如何将发送回控制器的参数命名为一个问题,但是在@Html.BeginForm()
中设置值的任何组合似乎都没有。
在这里有人对我有什么建议吗?

要使用自动模型绑定,您应该使用属性而不是视图模型中的字段。希望这可以解决问题:
public class ASideReceivingViewModel
{
public PurchaseOrderLine poLine { get; set; };
public ReceivingItem receivingItem { get; set; };
...
}
