ボタンは繰り返しGETメソッドを呼び出し、編集時にPOSTしません。

Question

私のデータベース内のエントリを編集しようとしていますが、submitをクリックするとGETメソッドが何度も何度も呼び出され続けます。私はブレークポイントを介してこれをテストしましたが、POSTメソッドが実行されているという証拠はありません - 私の製造元バインドとは何か？

// GET: Model/Edit/5 
    public ActionResult Edit(int? id) 
    { 
     if (id == null) 
     { 
      return new HttpStatusCodeResult(HttpStatusCode.BadRequest); 
     } 
     Model model = db.Models.Find(id); 
     if (model == null) 
     { 
      return HttpNotFound(); 
     } 

     ViewBag.Manufacturers = GetManufacturerList(model); 

     return View(model); 
    }

    [HttpPost]

    public ActionResult EditPost(int? id) 
    { 
     if (id == null) 
     { 
      return new HttpStatusCodeResult(HttpStatusCode.BadRequest); 
     } 
     var modelToUpdate = db.Models.Find(id); 
     if (TryUpdateModel(modelToUpdate, "", 
      new string[] { "ModelName", "ManufacturerID" })) 
     { 
      try 
      { 
       db.SaveChanges(); 

       return RedirectToAction("Index"); 
      } 
      catch (DataException /* dex */) 
      { 
       //Log the error (uncomment dex variable name and add a line here to write a log. 
       ModelState.AddModelError("", "Unable to save changes. Try again, and if the problem persists, see your system administrator."); 
      } 
     } 

     ViewBag.Manufacturers = GetManufacturerList(); 

     return View(modelToUpdate); 
    }

感謝。どんな助けでも大歓迎です。

Answer 1

HttpPostメソッドの名前は "EditPost"です。このように単に「編集」する必要はありませんか？ここで

[HttpPost] 
[ValidateAntiForgeryToken] 
public ActionResult Edit(Model model) 
{

Answer 2

- 私は以下のようにACTIONNAME属性を追加するのを忘れ：

[HttpPost, ActionName("Edit")] 
[ValidateAntiForgeryToken] 
public ActionResult EditPost(int? id) 
{...}
