Question

这是一个非常简单的例子,但应当足以表明我的问题。我需要通过模型来看待用户将进行更新,但这一观点还需要一些其他数据,以形成从下名单或提供其他信息。

根据以下守则,I希望避免使用<代码>ViewBag/ViewData/code>,这样我就能够把问题List和-PaswordLength结合起来。 (引入“超级例子情景”) 更改安全问题或产生新的观点或其他目标?



[Authorize]
public ActionResult ChangeSecurityQuestion() {
  var user = Membership.GetUser();
  if (user != null) {
    var model = new ChangeSecurityQuestionModel() {
      PasswordQuestion = user.PasswordQuestion
    };
    ViewBag.QuestionList = new SelectList(membershipRepository.GetSecurityQuestionList(), "Question", "Question");
    ViewBag.PasswordLength = MembershipService.MinPasswordLength;
    return View(model);
  }

  // user not found
  return RedirectToAction("Index");
}

[Authorize]
[HttpPost]
public ActionResult ChangeSecurityQuestion(ChangeSecurityQuestionModel model) {
  if (ModelState.IsValid) {
    var user = Membership.GetUser();
    if (user != null) {
      if (user.ChangePasswordQuestionAndAnswer(model.Password, model.PasswordQuestion, model.PasswordAnswer)) {
        return View("ChangeQuestionSuccess");
      } else {
        ModelState.AddModelError("", "The password is incorrect.");
      }
    }
  }

  // If we got this far, something failed, redisplay form
  ViewBag.QuestionList = new SelectList(membershipRepository.GetSecurityQuestionList(), "Question", "Question");
  ViewBag.PasswordLength = MembershipService.MinPasswordLength;
  return View(model);
}

Answer 1

为什么不把问题语言和密码放在你们的变革安全问题上

var model = new ChangeSecurityQuestionModel() {
      PasswordQuestion = user.PasswordQuestion,
      QuestionList = new SelectList(membershipRepository.GetSecurityQuestionList(), "Question", "Question"),
      PasswordLength = MembershipService.MinPasswordLength;
    };

Answer 2

反复出现的“多用途观点”或继续增加模型”问题的一个替代办法是为HtmlHelper创造推广方法:

public static class HtmlExtensions
{
     public static MvcHtmlString SecurityQuestionDropDown(this HtmlHelper helper)
     {
          return helper.DropDownList(....,new SelectList(membershipRepository.GetSecurityQuestionList(), "Question", "Question"));
     }
}

Answer 3

可在<条码>上添加<问题List和<条码>。之后:

[Authorize]
public ActionResult ChangeSecurityQuestion() {
    var user = Membership.GetUser();
    if (user != null) {
        var model = new ChangeSecurityQuestionModel() {
            PasswordQuestion = user.PasswordQuestion,
            QuestionList = new SelectList(membershipRepository.GetSecurityQuestionList(), "Question", "Question"),
            PasswordLength = MembershipService.MinPasswordLength
        };
        return View(model);
    }
    // user not found
    return RedirectToAction("Index");
}

[Authorize]
[HttpPost]
public ActionResult ChangeSecurityQuestion(ChangeSecurityQuestionModel model) {
    if (ModelState.IsValid) {
        var user = Membership.GetUser();
        if (user != null) {
            if (user.ChangePasswordQuestionAndAnswer(model.Password, model.PasswordQuestion, model.PasswordAnswer)) {
                return View("ChangeQuestionSuccess");
            } else {
                ModelState.AddModelError("", "The password is incorrect.");
            }
        }
    }
    // If we got this far, something failed, redisplay form
    model.QuestionList = new SelectList(membershipRepository.GetSecurityQuestionList(), "Question", "Question");
    model.PasswordLength = MembershipService.MinPasswordLength;
    return View(model);
}
