學用MVC4做網站二：2.3修改用戶組

一、用戶

二、用戶組

2.1瀏覽用戶組

2.2添加用戶組

2.3修改用戶組

首先打開【UserGroupController】，修改[Edit(int Id)] Action

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

右鍵添加強類型視圖，並修改視圖代碼（與添加用戶組類似）

@model Ninesky.Models.UserGroup

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

修改處理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 = "用戶組不存在", Details = "修改用戶時發生錯誤，修改的用戶組不存在。", Cause = "該用戶組已被其他管理員刪除", Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("List", "UserGroup") + "'>用戶組列表</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 = "成功修改了用戶組信息", DwellTime = 3, NavigationName = "用戶組列表", NavigationUrl = Url.Action("List", "UserGroup") };
                return RedirectToAction("ManageNotice", "Prompt", _n);
            }
            else
            {
                Error _e = new Error { Title = "更新數據失敗", Details = "修改用戶組信息時修改的信息未能保存到數據庫。", Cause = Server.UrlEncode("<li>您並未更改用戶組信息。</li><li>數據庫未知錯誤。</li>"), Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("List", "UserGroup") + "'>用戶組列表</a></li><li>重新<a href='" + Url.Action("Edit", "UserGroup", new { id = userGroup.UserGroupId }) + "'>修改用戶組</a></li>") };
                return RedirectToAction("ManageError", "Prompt", _e);
            }
        }

瀏覽器中打開看一下

點保存

保存成功了。
