私は人物モデルを持っています:
Partial Public Class Person
Public Property Id As Long
<DisplayName("Fornavn")>
Public Property Firstname As String
<DisplayName("Efternavn")>
Public Property Lastname As String
Public Property chr_cpr As String
<DisplayName("Medarbejdernummer")>
Public Property EmployeeNumber As String
Public Overridable Property Accounts As ICollection(Of Account) = New HashSet(Of Account)
Public Overridable Property PaymentCards As ICollection(Of PaymentCard) = New HashSet(Of PaymentCard)
Public Overridable Property PaymentRoles As ICollection(Of PaymentRole) = New HashSet(Of PaymentRole)
Public Overridable Property AllPaymentRoles As ICollection(Of PaymentRole) = New HashSet(Of PaymentRole)
Public Overridable Property BillableDepartments As ICollection(Of Department) = New HashSet(Of Department)
Public Overridable Property AllDepartments As ICollection(Of Department) = New HashSet(Of Department)
Public Overridable Property AccessablePosDevices As ICollection(Of PosDevice) = New HashSet(Of PosDevice)
Public Overridable Property AllPosDevices As ICollection(Of PosDevice) = New HashSet(Of PosDevice)
End Class
そしてアカウントモデル:
Partial Public Class Account
Public Property Id As Long
Public Property PersonId As Long
Public Property Balance As Decimal
Public Property SchemaId As Long
Public Property HasAutoRefill As Boolean
Public Overridable Property Schema As AccountSchema
Public Overridable Property Person As Person
End Class
そして paymentCard モデル:
Partial Public Class PaymentCard
Public Property Id As Long
Public Property Serial As String
Public Property TypeId As Nullable(Of Long)
Public Property IsActive As Boolean
Public Property PersonId As Long
Public Overridable Property Type As CardType
Public Overridable Property Person As Person
End Class
Person/Edit ビューから Person、PaymentCard、および Account プロパティを編集できるようにしたいと考えています。EditorTemplates を使用しています。これは私の見解です:
@ModelType IDCompany.WEB.Person
@Using Html.BeginForm()
@Html.ValidationSummary(True)
@<fieldset>
<legend>Person</legend>
@Html.HiddenFor(Function(model) model.Id)
<div class="editor-label">
@Html.LabelFor(Function(model) model.Firstname)
</div>
<div class="editor-field">
@Html.EditorFor(Function(model) model.Firstname)
@Html.ValidationMessageFor(Function(model) model.Firstname)
</div>
<div class="editor-label">
@Html.LabelFor(Function(model) model.Lastname)
</div>
<div class="editor-field">
@Html.EditorFor(Function(model) model.Lastname)
@Html.ValidationMessageFor(Function(model) model.Lastname)
</div>
<div class="editor-label">
@Html.LabelFor(Function(model) model.chr_cpr)
</div>
<div class="editor-field">
@Html.EditorFor(Function(model) model.chr_cpr)
@Html.ValidationMessageFor(Function(model) model.chr_cpr)
</div>
<div class="editor-label">
@Html.LabelFor(Function(model) model.EmployeeNumber)
</div>
<div class="editor-field">
@Html.EditorFor(Function(model) model.EmployeeNumber)
@Html.ValidationMessageFor(Function(model) model.EmployeeNumber)
</div>
</fieldset>
@<table class="cardTable">
<tr>
<th>Id</th>
<th>Serienummer</th>
<th>Type</th>
<th>Aktiv</th>
</tr>
@Html.EditorFor(Function(x) x.PaymentCards)
</table>
@Html.EditorFor(Function(x) x.Accounts)
@<p><input type="submit" value="Save" /></p>
End Using
<div>
@Html.ActionLink("Back to List", "Index")
</div>
@Section Scripts
@Scripts.Render("~/bundles/jqueryval")
End Section
これが私の Person/EditorTemplates/Account です:
@ModelType IDCompany.WEB.Account
@Html.EditorFor(Function(model) model.PersonId)
@Html.EditorFor(Function(model) model.Id)
@Html.EditorFor(Function(model) model.HasAutoRefill)
@Html.EditorFor(Function(model) model.SchemaId)
そして、私の Person/EditorTemplates/PaymentCard:
@ModelType IDCompany.WEB.PaymentCard
@Html.HiddenFor(Function(model) model.TypeId)
@Html.HiddenFor(Function(model) model.PersonId)
@Html.HiddenFor(Function(model) model.Id)
@Html.HiddenFor(Function(model) Model.Serial)
@Html.HiddenFor(Function(model) Model.Type.Name)
<tr class="cardRow">
<td>@Model.Id</td>
<td>@Model.Serial</td>
<td>@Model.Type.Name</td>
<td>@Html.EditorFor(Function(model) model.IsActive)</td>
</tr>
そして、これは私の PersonController の編集機能です:
<HttpPost()> _
Function Edit(ByVal person As Person) As ActionResult
Dim kontoSubMenu As New List(Of MenuPoint)
Dim emptyList As New List(Of String)
kontoSubMenu.Add(New MenuPoint("Kantine", emptyList, "Kontooplysninger", "Home", "All"))
kontoSubMenu.Add(New MenuPoint("Personer", emptyList, "Personer", "Person", "All"))
kontoSubMenu.Add(New MenuPoint("Test", emptyList, "LogUd", "Home", "All"))
ViewBag.kontoSubMenu = kontoSubMenu
If ModelState.IsValid Then
Dim paymentcardList
paymentcardList = person.PaymentCards.ToList()
For Each pc In paymentcardList
db.Entry(pc).State = EntityState.Modified
db.SaveChanges()
Next
Dim accountList
accountList = person.Accounts.ToList()
For Each ac As Account In accountList
db.Entry(ac).State = EntityState.Modified
'Dim accountValue As Account = db.Accounts.Find(accountt.Id)
db.SaveChanges()
Next
db.Entry(person).State = EntityState.Modified
db.SaveChanges()
Return RedirectToAction("Index")
End If
Return View(person)
End Function
私はMVCが初めてです。ビューでいくつかのデータを編集しようとすると、「参照整合性制約違反が発生しました: 参照制約を定義するプロパティ値が、リレーションシップのプリンシパル オブジェクトと依存オブジェクトの間で一貫していません。」というエラーが表示されます。「db.Entry(pc).State = EntityState.Modified」について
私は何を間違っていますか?
