MVC4制作网站教程第三章 修改用户组操作3.3

一、用户 
二、用户组 
2.1浏览用户组 
2.2添加用户组 
2.3修改用户组 
首先打开【UserGroupController】，修改[Edit(int Id)] Action 

/// <summary>
 /// 修改用户组
 /// </summary>
 /// <param name="Id">用户组Id</param>
 /// <returns></returns>
 [AdminAuthorize]
 public ActionResult Edit(int Id)
 {
 userGroupRsy = new UserGroupRepository();
 var _userGroup = userGroupRsy.Find(Id);
 return View(_userGroup);
 }

右键添加强类型视图，并修改视图代码（与添加用户组类似）

@model Ninesky.Models.UserGroup

@{
 ViewBag.Title = "修改用户组";
 Layout = "~/Views/Layout/_Manage.cshtml";
}
<div class="left">
 <div class="top"></div>
 左侧列表
</div>
<div class="split"></div>
<div class="workspace">
 <div class="inside">
 <div class="notebar">
 <img alt="" src="~/Skins/Default/Manage/Images/UserGroup.gif" />修改用户组资料
 </div>
 @using (Html.BeginForm("Eidt","UserGroup"))
 {
 @Html.ValidationSummary(true)
 <fieldset>
 <legend>用户组资料</legend>

 @Html.HiddenFor(model => model.UserGroupId)
 <ul>
  <li>
  <div class="editor-label">
  @Html.LabelFor(model => model.Type)
  </div>
  <div class="editor-field">
  @Html.DisplayTextFor(model => model.Type)
  </div>
  </li>
  <li>
  <div class="editor-label">
  @Html.LabelFor(model => model.Name)
  </div>
  <div class="editor-field">
  @Html.EditorFor(model => model.Name)
  @Html.ValidationMessageFor(model => model.Name)
  </div>
  </li>
  <li>
  <div class="editor-label">
  @Html.LabelFor(model => model.Description)
  </div>
  <div class="editor-field">
  @Html.EditorFor(model => model.Description)
  @Html.ValidationMessageFor(model => model.Description)
  </div>
  </li>
  <li>
  <div class="editor-label">
  </div>
  <div class="editor-field">
  <input type="submit" value="保存" />
  </div>
  </li>
 </ul>
 </fieldset>
 }
 </div>
</div>
<div class="clear"></div>
@section Scripts {
 @Scripts.Render("~/bundles/jqueryval")
}

修改处理Action[Eidt(UserGroup userGroup)] 

[HttpPost]
 [AdminAuthorize]
 public ActionResult Eidt(UserGroup userGroup)
 {
 userGroupRsy = new UserGroupRepository();
 var _userGroup = userGroupRsy.Find(userGroup.UserGroupId);
 if (_userGroup == null)
 {
 Error _e = new Error { Title = "用户组不存在", Details = "修改用户时发生错误，修改的用户组不存在。", Cause = "该用户组已被其他管理员删除", Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("List", "UserGroup") + "'>用户组列表</a></li>") };
 return RedirectToAction("ManageError", "Prompt", _e);
 }
 _userGroup.Name = userGroup.Name;
 _userGroup.Description = userGroup.Description;
 if (userGroupRsy.Update(_userGroup))
 {
 Notice _n = new Notice { Title = "修改成功", Details = "成功修改了用户组信息", DwellTime = 3, NavigationName = "用户组列表", NavigationUrl = Url.Action("List", "UserGroup") };
 return RedirectToAction("ManageNotice", "Prompt", _n);
 }
 else
 {
 Error _e = new Error { Title = "更新数据失败", Details = "修改用户组信息时修改的信息未能保存到数据库。", Cause = Server.UrlEncode("<li>您并未更改用户组信息。</li><li>数据库未知错误。</li>"), Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("List", "UserGroup") + "'>用户组列表</a></li><li>重新<a href='" + Url.Action("Edit", "UserGroup", new { id = userGroup.UserGroupId }) + "'>修改用户组</a></li>") };
 return RedirectToAction("ManageError", "Prompt", _e);
 }
 }
