MVCアーキテクチャとEntityFramework（データベースファースト）を使用してイントラネットASPWebアプリケーションを開発しています。私の問題は次のとおりです。

エンティティ「Person」と、外部キーとして「Person」の主キー（つまり、Id_Person）を含むエンティティ「PhoneCard」があります。Entity Frameworkを使用してCRUDコントローラー「PersonController」を作成しました。VisualStudioは、対応するビュー（インデックス、詳細、作成、編集、削除）を自動的に生成しました。次に、「PhoneCardController」という名前の別のCRUDコントローラー（常にEFを使用）を作成しました。私のCreatePersonビューには、AJAX関数のおかげでCreatePhoneCardビューが含まれています。

function addPhoneCardCreateView() {

    $('#divCreatePhoneCard').load("@Url.Action("Create","PhoneCard")");

}

そしてそれをそのように呼んでください：

<a href = "javascript:addPhoneCardCreateView()">Add a Phone card</a>
    <div id = "divCreatePhoneCard"></div>

これにより、部分ビューを呼び出して、人を追加しているときにテレホンカードを追加できるようにします。残念ながら、[作成]ボタンをクリックすると、データベースに新しい人が追加されるだけです。これが私のPersonControllerのCreateアクションです：

        public ActionResult Create()
    {
        ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories, "Id_ProductPackageCategory", "Name");
        return View();
    }

    //
    // POST: /Person/Create

    [HttpPost]
    public ActionResult Create(Person person)
    {
        if (ModelState.IsValid)
        {

            db.Persons.AddObject(person);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories, "Id_ProductPackageCategory", "Name", person.Id_ProductPackageCategory);
        return View(person);
    }

    Layout = null;

モデルには、を尊重しなかったため、Postアクションでは常にnullでPersonあるコレクションプロパティがあります。また、あなたは部分的なビューではなく、完全なビューです（間違っているタグが含まれています）。PhoneCardsnaming convention for binding to a listPhoneCard.cshtml<html><body>
