Question

剃刀代码：

 @model Clarifi.API.DataContract.ManualScanItem
    @using (Html.BeginForm(new { @class = "pull-left" }))
    { 
        @Html.HiddenFor(m => m.ItemType)
        @Html.HiddenFor(m => m.ItemIdentifier)
        @Html.HiddenFor(m => m.Hotel.Address.AddressLine1)
        @Html.HiddenFor(m => m.Hotel.Address.AddressLine2)
        @Html.HiddenFor(m => m.Hotel.Address.CityCode)
        @Html.HiddenFor(m => m.Hotel.Address.CityName)
        @Html.HiddenFor(m => m.Hotel.Address.CompleteAddress)
        @Html.HiddenFor(m => m.Hotel.Address.CountryCode)
        @Html.HiddenFor(m => m.Hotel.Address.StateCode)
        @Html.HiddenFor(m => m.Hotel.Address.StateName)
        @Html.HiddenFor(m => m.Hotel.Address.ZipCode)
        @Html.HiddenFor(m => m.Hotel.ClarifiId)
        @Html.HiddenFor(m => m.Hotel.GeoCode.Latitude)
        @Html.HiddenFor(m => m.Hotel.GeoCode.Longitude)
        @Html.HiddenFor(m => m.Hotel.GeoCode.GeoCodeSource)
        @Html.HiddenFor(m => m.Hotel.HasIssue)
        @Html.HiddenFor(m => m.Hotel.Name)
        @Html.HiddenFor(m => m.Hotel.PhoneNumber)
        @Html.HiddenFor(m => m.Hotel.Rating)
        @Html.HiddenFor(m => m.Hotel.SupplierFamily)
        @Html.HiddenFor(m => m.Hotel.SupplierId)

        <input type="submit" value="Verify" class="button-orange btn-action mtm btn-validate">
    }

控制器中的动作：

public ActionResult MapGeoCode(ManualScanItem hotelModel)
        {
            ItemRs<ManualScanItem> response = manualScanProvider.GetNextScanItem(ManualScanItemType.GeoCodeScan);

            if (!response.IsSuccess)
            {
                //this.SetErrorView(response);
                return View("ErrorView");
            }

            return View(response.Item);
        }

我甚至检查了http请求。还有输入数据。但在我的控制器动作中，'hotelModel'为空。该怎么办？为什么会这样呢？

Answer 1

您将模型传递到某个地方的视图？类似的东西：

    [HttpGet]
    public ActionResult MapGeoCode()
    {
        return View(new ManualScanItem());
    }

    [HttpPost]
    public ActionResult MapGeoCode(ManualScanItem hotelModel)
    {
        ItemRs<ManualScanItem> response = manualScanProvider.GetNextScanItem(ManualScanItemType.GeoCodeScan);

        if (!response.IsSuccess)
        {
            //this.SetErrorView(response);
            return View("ErrorView");
        }

        return View(response.Item);
    }

Answer 2

[HttpGet]
public ActionResult MapGeoCode()
{
    return View();
}

[HttpPost]
public ActionResult MapGeoCode(ManualScanItem hotelModel)
{
    ItemRs<ManualScanItem> response = manualScanProvider.GetNextScanItem(ManualScanItemType.GeoCodeScan);

    if (!response.IsSuccess)
    {
        return View("ErrorView");
        //or return get action
        return View(response.Item);
    }

    return RedirectToAction("Index");
}

在视图中尝试这个：

@using (Html.BeginForm("MapGeoCode", "Controller", FormMethod.Post, new { @class = "pull-left" }))
{
  //...
}

Answer 3

使用此重载..

@using (Html.BeginForm("actionname", "controllername", FormMethod.Post, new { @class = "your class name" })) { 

}

为什么模型没有被控制器动作接收？
