Question

我正在尝试从视图中发布模型。我发布的模型总是错误的，此刻第二个属性什么都没有。通过不同的方法，有时我会填充展位属性，但是这两个属性中的属性什么都没有。

对不起，我英语不好。希望您能理解我的问题。

根据谷歌，模型绑定搞砸了，所以我应该在POST方法中为我的属性使用一个不同的名称。没有工作。我还读到我可以为模型中的每个属性尝试使用两个参数“ Anfang”和“ Ende”。没有工作。

我的模特：

Public Class Stempel
    Public Property ID As Integer
    <Required>
    Public Property Gestempelt As Date
    <Required>
    Public Overridable Property Mitarbeiter As Mitarbeiter
    <Required>
    Public Overridable Property Stempelstati As Stempelstati
End Class

<NotMapped>
Public Class StempelBearbeiten
    Public Property Anfang As Stempel
    Public Property Ende As Stempel
End Class

我的Get-Method，用于编辑数据：

Function StempelBearbeiten(ByVal id As Integer?, ByVal ende As Integer?) As ActionResult
        If id Is Nothing OrElse ende Is Nothing Then
            Return New HttpStatusCodeResult(Net.HttpStatusCode.BadRequest)
        End If
        Dim stempelAnfang = entity.Stempel.Find(id)
        Dim stempelEnde = entity.Stempel.Find(ende)
        If stempelAnfang Is Nothing OrElse stempelEnde Is Nothing Then
            Return New HttpStatusCodeResult(Net.HttpStatusCode.NotFound)
        End If
        Dim t As New StempelBearbeiten With {
            .Anfang = New Stempel With {.ID = stempelAnfang.ID, .Gestempelt = stempelAnfang.Gestempelt, .Stempelstati = stempelAnfang.Stempelstati},
            .Ende = New Stempel With {.ID = stempelEnde.ID, .Gestempelt = stempelEnde.Gestempelt}}
        ViewData("Stempelliste") = New SelectList(entity.Stempelstati.Where(Function(x) x.Aktiv).ToList, "ID", "Bezeichnung", stempelAnfang.Stempelstati.ID)
        Return View(t)
    End Function

我的观点：

@ModelType ZeiterfassungWebMvc.Models.StempelBearbeiten
@Code
ViewData("Title") = "StempelBearbeiten"
End Code
@Using (Html.BeginForm())
@Html.AntiForgeryToken()

                                                                                End Sub).GetHtml
                </div>

        </div>
        <div class="form-group">
            <label>Stempelbezeichnung</label>
            @Html.HiddenFor(Function(x) x.Anfang.Stempelstati.ID)
            @Html.DropDownListFor(Function(x) x.Anfang.Stempelstati.ID, DirectCast(ViewData("Stempelliste"), SelectList), New With {.class = "selectpicker form-control", .title = "Bitte wählen Sie eine Rolle aus"})
        </div>

        <div Class="form-group">
            <div Class="btn-group" role="group" aria-label="Bearbeitung">
                <input type="submit" value="Speichern" Class="btn btn-success" />
                @Html.ActionLink("Abbrechen & Zurück", "Übersicht", Nothing, New With {.class = "btn btn-danger"})
            </div>
        </div>
    </div>
</div>
End Using

我的POST方法：

<HttpPost>
    <ValidateAntiForgeryToken>
    <ActionName("StempelBearbeiten")>
    Function Bearbeiten(ByVal brb As Models.StempelBearbeiten) As ActionResult

    End Function

为什么某些模型属性为空/无？
