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);
 }
 }
