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 class="clear"></div>

@section Scripts {

@Scripts.Render("~/bundles/jqueryval")

}

修改处理Action[Eidt(UserGroup userGroup)]

[HttpPost]

[AdminAuthorize]

publicActionResultEidt(UserGroupuserGroup)

{

userGroupRsy=newUserGroupRepository();

var_userGroup=userGroupRsy.Find(userGroup.UserGroupId);

if(_userGroup==null)

{

Error_e=newError{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<ahref='"+Url.Action("List","UserGroup")+"'>用户组列表</a></li>")};

returnRedirectToAction("ManageError","Prompt",_e);

}

_userGroup.Name=userGroup.Name;

_userGroup.Description=userGroup.Description;

if(userGroupRsy.Update(_userGroup))

{

Notice_n=newNotice{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")};

returnRedirectToAction("ManageNotice","Prompt",_n);

}

else

{

Error_e=newError{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<ahref='"+Url.Action("List","UserGroup")+"'>用户组列表</a></li><li>重新<ahref='"+Url.Action("Edit","UserGroup",new{id=userGroup.UserGroupId})+"'>修改用户组</a></li>")};

returnRedirectToAction("ManageError","Prompt",_e);

}

}
