剃刀視圖未顯示導航屬性值

Question

我有以下動作的方法： - ：即我是

<td> 
     @Html.DisplayFor(modelItem => Model.Description) 
    </td> 
    <td> 
     @Html.DisplayFor(modelItem => Model.Answer_Description.description) 
    </td> 
    <td> 
    @Ajax.ActionLink("Delete", "Delete", "Answer", 
    new { id = Model.AnswersID }, 
     new AjaxOptions 
     { 
      Confirm = "Are You sure You want to delete this Answer ?", 
      HttpMethod = "Post", 
      UpdateTargetId = Model.AnswersID.ToString() 
        }) 


    </td> 
    </tr> 

問題 -

[HttpPost] 
     public ActionResult Create(int questionid, Answer a) 
     { 
      if (ModelState.IsValid) 
      { 
     repository.AddAnswer(a); 
      repository.Save(); 
      return PartialView("_details",a); 
      } 
      return View(a); 

和folloiwng _details partila視圖面對的是，@Html.DisplayFor(modelItem => Model.Answer_Description.description)價值是不會自動顯示ajx調用後，除非我刷新網頁，所以可能是什麼問題？

Answer 1

我會懷疑一個懶加載問題（很難確保用你給的相關信息，但）...

至於Model.Description似乎是一種原始（String）屬性，但Answer_Description.description是導航屬性的原始屬性。

是否確定Answer_Description正確加載？

編輯：更確切地說：您的操作收到答案：通過時是否具有Answer_Description.description？ 如果不是，您應該在返回查看之前從數據庫中獲取Answer_Description ...
