は、なぜあなたはdb.PurchaseInvoiceDetailsTables.Add（model.PurchaseInvoiceDetailsTable） '呼び出している：あなたはこれを使用することができます検証エラーを見るために

。（model.PaymentTerm）;を2回追加する。さらに、_ EntityValidationErrorsプロパティを参照してください詳細はこちら –

そして、なぜ世界中に隠れた入力があるのですか？ビューモデルを使用する。 –

2回はテストを行っていません==、隠れた入力は自動的に挿入されますが、ユーザは隠し値を入力しません。 – nonstop328

であるあなたが取得している例外は、あなたが保存しようとしている事業体の特性の1つ以上ではないことを意味し有効です。例えば列がnullではなく、保存しようとしているプロパティがnullであると定義されています。 ; `と` db.PaymentTerms

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);
