MVC4制作網站教程第二章 用戶修改資料2.4

一、用戶 
1.1用戶注冊 
1.2用戶登錄 
1.3修改密碼 
1.4修改資料 

在用戶登陸成功後要跳轉到一個頁面，暫且叫做用戶中心吧。在【UserController】添加[default] action 

[UserAuthorize]
 public ActionResult Default()
 {
  userRsy = new UserRepository();
  var _user = userRsy.Find(UserName);
  return View(_user);
 } 

添加相應對應強類型視圖 

@model Ninesky.Models.User
@{
 ViewBag.Title = "首頁";
 Layout = "~/Views/Layout/_User.cshtml";
}

<div class="leftnav">這裡左側導航列表</div>
<div class="workspace">
 <div class ="Nav">您現在的位置： 用戶首頁</div>
 <div>@Model.UserName
 <br />
 @Model.GroupId
 </div>
</div> 

現在要把左側導航列表做出來，在視圖的User文件夾上點右鍵新建局部視圖PartialPersonalNav

<ul>
 <li>@Html.ActionLink("用戶首頁","Default","User")</li>
 <li>@Html.ActionLink("修改信息","ChangeInfo","User")</li>
 <li>@Html.ActionLink("修改密碼","ChangePassword","User")</li>
 <li>@Html.ActionLink("退出系統","Logout","User")</li>
</ul> 

將default.cshtml中“這裡左側導航列表”替換為@Html.Partial("PartialPersonalNav")。浏覽器中打開，導航列表顯示出來了。 

現在開始做修改用戶資料了。在【UserController】添加[ChangeInfo] action 

[UserAuthorize]
 public ActionResult ChangeInfo()
 {
  userRsy = new UserRepository();
  var _user = userRsy.Find(UserName);
  return View(_user);
 } 

添加修改資料的處理 action

[HttpPost]
 [UserAuthorize]
 public ActionResult ChangeInfo(User user)
 {
  userRsy = new UserRepository();
  if(userRsy.Authentication(UserName,Ninesky.Common.Text.Sha256(user.Password))==0)
  {
  var _user = userRsy.Find(UserName);
  _user.Gender = user.Gender;
  _user.Email = user.Email;
  _user.QQ = user.QQ;
  _user.Tel = user.Tel;
  _user.Address = user.Address;
  _user.PostCode = user.PostCode;
  if (userRsy.Update(_user))
  {
   Notice _n = new Notice { Title = "修改資料成功", Details = "您已經成功修改資料！", DwellTime = 5, NavigationName = "用戶首頁", NavigationUrl = Url.Action("Default", "User") };
   return RedirectToAction("UserNotice", "Prompt", _n);
  }
  else
  {
   Error _e = new Error { Title = "修改資料失敗", Details = "在修改用戶資料時時，更新的資料未能保存到數據庫", Cause = "系統錯誤", Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("ChangeInfo", "User") + "'>修改資料</a>頁面，輸入正確的信息後重新操作</li><li>聯系網站管理員</li>") };
   return RedirectToAction("UserError", "Prompt", _e);
  }
  }
  else
  {
  ModelState.AddModelError("Password","密碼錯誤！");
  return View();
  }
  
  
 } 

aciton上右鍵添加強類型視圖，修改視圖裡自動生成代碼，完成後。如下： 

@model Ninesky.Models.User

@{
 ViewBag.Title = "修改個人資料";
 Layout = "~/Views/Layout/_User.cshtml";
}

<div class="leftnav">@Html.Partial("PartialPersonalNav")</div>
<div class="workspace">
 <div class="Nav">您現在的位置： 用戶首頁</div>
 <div>
 @using (Html.BeginForm())
 {
  @Html.ValidationSummary(true)

  <fieldset>
  <legend>修改資料</legend>
  @Html.HiddenFor(model => model.UserId)
  <ul>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.UserName)
   </div>
   <div class="editor-field">
    @Html.DisplayFor(model => model.UserName)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.Password)
   </div>
   <div class="editor-field">
    @Html.Password("Password")
    @Html.ValidationMessageFor(model => model.Password)
    輸入正確的密碼才能修改資料。
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.Gender)
   </div>
   <div class="editor-field">
    @Html.RadioButtonFor(model => model.Gender, 0) 男
   @Html.RadioButtonFor(model => model.Gender, 1) 女
   @Html.RadioButtonFor(model => model.Gender, 2) 保密
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.Email)
   </div>
   <div class="editor-field">
    @Html.EditorFor(model => model.Email)
    @Html.ValidationMessageFor(model => model.Email)
    @Html.DisplayDescriptionFor(model => model.Email)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.QQ)
   </div>
   <div class="editor-field">
    @Html.EditorFor(model => model.QQ)
    @Html.ValidationMessageFor(model => model.QQ)
    @Html.DisplayDescriptionFor(model => model.QQ)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.Tel)
   </div>
   <div class="editor-field">
    @Html.EditorFor(model => model.Tel)
    @Html.ValidationMessageFor(model => model.Tel)
    @Html.DisplayDescriptionFor(model => model.Tel)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.Address)
   </div>
   <div class="editor-field">
    @Html.EditorFor(model => model.Address)
    @Html.ValidationMessageFor(model => model.Address)
    @Html.DisplayDescriptionFor(model => model.Address)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.PostCode)
   </div>
   <div class="editor-field">
    @Html.EditorFor(model => model.PostCode)
    @Html.ValidationMessageFor(model => model.PostCode)
    @Html.DisplayDescriptionFor(model => model.PostCode)
   </div>
   </li>
   <li><input type="submit" value="修改" /></li>
  </ul>
  </fieldset>
 }
 </div>
</div>

@section Scripts {
 @Scripts.Render("~/bundles/jqueryval")
} 

運行一下看

輸入資料測試一下。能夠正常保存到數據庫。 

====================================== 
剛開始學MVC，加之表達能力有限，也沒有事先寫個大致計劃，寫的很差、很亂。現在是想到哪裡就寫哪裡，有時候做到後面了，發現前邊寫的不行又去改前面寫的代碼。
