学用MVC4做网站二：2.3修改用户组

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);

            }

        }

浏览器中打开看一下

点保存

保存成功了。
