我提出了一种方法，用于批准或拒绝用户注册表单中的注册请求。
当用户提交表单时，请求将变为待处理状态，然后管理员有权拒绝或批准该请求;但我的方法不能正常工作，因为没有任何事情发生。
当我点击拒绝或批准按钮时，应用程序只刷新页面。
有谁能告诉我我的代码有什么问题？代码片段如下。
这是审批控制器
public class ApprovedRegistrationController :BaseAdminController
{
// GET: Admin/ApproveRegistration
public ActionResult Index(string Status)
{ ViewBag.Status = (Status == null ? "P" : Status);
if (Status == null)
{ var register = objBs.registerBs.GetALL().Where(x => x.Approved == "P").ToList();
return View(register); }
else
{ var register = objBs.registerBs.GetALL().Where(x => x.Approved == Status).ToList();
return View(register); }}
public ActionResult Approve(int id)
{ try
{ var myRegistration = objBs.registerBs.GetByID(id);
myRegistration.Approved = "A";
objBs.registerBs.Update(myRegistration);
TempData["Msg"] = "Approved Successfully";
return RedirectToAction("Index"); }
catch (Exception e1)
{ TempData["Msg"] = "Approved Failed: " + e1.Message;
return RedirectToAction("Index");}}
public ActionResult Reject(int id)
{try
{ var myRegistration = objBs.registerBs.GetByID(id);
myRegistration.Approved = "R";
objBs.registerBs.Update(myRegistration);
TempData["Msg"] = "Rejected Successfully";
return RedirectToAction("Index");}
catch (Exception e1)
{ TempData["Msg"] = "Rejection Failed: " + e1.Message;
return RedirectToAction("Index");}}}
注册批准或拒绝视图
@model IEnumerable<XtechWebsite.Models.Registration>
@{
ViewBag.Title = "Index";}
<h2>Index</h2>
<script>
function ConfirmApprove() {
return confirm('Are u sure to accept it?');
}
function ConfirmReject() {
return confirm('Are u sure to reject it?');
}
</script>

答案 0 :(得分：2)
您不会在上下文中调用SaveChanges，说明您的修改未持久存储到数据库的原因。
您可以在更新方法中添加对Save()的通话。
