c# - MVC コントローラーがレコードを作成しない

Question

Create アクションで新しいレコードを作成しようとすると失敗しますが、エラーはありません。なぜそうでないのか、なぜエラーがないのか正確にはわかりません。検索アクションを使用して、作成アクションのいくつかのフィールドに入力し、残りの情報を入力しています。

[HttpPost]
    public ActionResult Create(Incident incident)
    {
        if (ModelState.IsValid)
        {
            db.Incidents.AddObject(incident);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        ViewBag.ErrorType = new SelectList(db.Errors, "ErrorID", "ErrorDescription", incident.ErrorType);
        ViewBag.IncidentID = new SelectList(db.IncidentItems, "IncidentID", "IncidentItem1", incident.IncidentID);

Answer 1

言うのは難しいです...できることはいくつかあります：-firebugを使用して、アクションにポストバックされているパラメーターを確認します-Createアクションの周囲にいくつかのブレークポイントを設定して、正しいオブジェクト/値が処理されているかどうかを確認します。
