Warum rufen Sie 'db.PurchaseInvoiceDetailsTables.Add (model.PurchaseInvoiceDetailsTable);' und 'db.PaymentTerms. Add (model.PaymentTerm); zweimal. Und was sagt _See 'Eigenschaft' EntityValidationErrors 'für mehr Details_ Ihnen –

Und warum in der Welt haben Sie alle diese versteckten Eingaben. Verwenden Sie Ansichtsmodelle. –

zweimal mache ich das Testen löschte nicht ==, versteckte Eingabe ist für wenn ich es erstelle wird automatisches Einfügen wird nicht lassen Benutzer geben Sie den versteckten Wert ein – nonstop328

Die Ausnahme, die Sie Mittel bekommen, dass eine oder mehrere der Einheiten Eigenschaften, die Sie nicht versuchen, zu speichern ist gültig. z.B. Die Spalte ist nicht null und die Eigenschaft, die Sie speichern möchten, ist null.

Um die Validierungsfehler sehen Sie diese verwenden können:

catch (DbEntityValidationException dbEx) 
{ 
    foreach (var validationErrors in dbEx.EntityValidationErrors) 
    { 
     foreach (var validationError in validationErrors.ValidationErrors) 
     { 
      Trace.TraceInformation("Property: {0} Error: {1}", 
            validationError.PropertyName, 
            validationError.ErrorMessage); 
     } 
    } 
}
