学用MVC4做网站二：2.3修改用户组

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。

年底了，这几天酒醉头晕厉害，好几天没写了，昨天终于写了一点，结果忘记吧代码打包发上来了。今天下午还是头晕的厉害写不了了，先把昨天的代码打包不上来吧。分享地址http://pan.baidu.com/share/link?shareid=118238&uk=2198133459
