我有顯示對象的列表和每個對象旁邊一個刪除Ajax.actionlink的folloiwng索引視圖: -如何傳遞時間戳與我Ajax.actionlink
<legend>@Model.Where(d => d.VisitStatu.Description.ToUpper().Equals("ASSINGED")).Count() @ViewBag.subtitle</legend>
<table>
<tr>
<th>Patient Full Name </th>
<th>Created BY</th>
<th></th>
</tr>
@foreach (var item in Model.Where(d => d.VisitStatu.Description.ToUpper().Equals("ASSINGED")))
{
<tr id = @item.VisitID>
<td>@Html.DisplayFor(modelItem => item.Patient.FullName)</td>
<td>@Html.DisplayFor(modelItem => item.CreatedBy)</td>
<td>@Ajax.ActionLink("Delete",
"Delete", "Visit",
new { id = item.VisitID },
new AjaxOptions
{
HttpMethod = "Post",
OnSuccess = "deletionconfirmation",
OnFailure = "deletionerror"
}
</td> </tr>
其中Ajax.actionlink會請撥打以下POST操作方法: -
[HttpPost]
public ActionResult Delete(int id)
{ try
{ var v = repository.GetVisit(id);
if (!(v.Editable(User.Identity.Name)))
{return View("NotFound"); }
repository.DeleteVisit(v);
repository.Save();
return Json(new { IsSuccess = "True", id = id, description = v.Date.ToString() }, JsonRequestBehavior.AllowGet);
}
catch (DbUpdateConcurrencyException)
{
return Json(new { IsSuccess = "False" }, JsonRequestBehavior.AllowGet);
}
catch (OptimisticConcurrencyException)
{
return Json(new { IsSuccess = "False" }, JsonRequestBehavior.AllowGet);
}}
但目前,如果用戶點擊刪除鏈接,該紀錄是由其他用戶則沒有DbUpdateConcurrencyException
將提高修改,,因爲我沒有通過時間戳的刪除行動方法...所以我如何包括時間amp的值與刪除ajax.actionlink? //提示該對象已包含timestamp屬性。 BR
感謝您的回覆,但是我如何告訴Post操作方法在發送到數據庫的刪除請求中包含時間戳? – 2012-04-26 11:59:32
@johnG,這個問題與ASP.NET MVC不再有任何關係。請開始一個新的線程,在那裏你解釋你的數據庫結構,你正在使用的數據訪問技術,如果你正在使用一個ORM如EF來顯示你的模型類...... – 2012-04-26 13:55:37
