MVC4做网站后台:模块管理1、修改模块信息

网站可能会包含一些模块：像文章、产品、图片、留言等。

栏目模块主要实现功能，启用或禁用模块，模块权限设置，模块上传设置等。

权限设置和上传设置以后专门考虑，先来显示或禁用模块。

1、在顶部导航栏添加管理连接

打开Home/Header.cshtml，在<nav>添加代码

2、添加Module接口

using Ninesky.Models;
using System.Linq;namespace Ninesky.Areas.Admin.Repository
{/// <summary>/// 后台管理模块接口/// <remarks>/// 版本v1.0/// 创建2013.12.10/// </remarks>/// </summary>interface InterfaceModule:Ninesky.Repository.InterfaceModule{/// <summary>/// 查找模块/// </summary>/// <returns>所有模块列表</returns>IQueryable<Module> Find();/// <summary>/// 修改模块信息/// </summary>/// <param name="module">模块</param>/// <returns>是否修改成功</returns>bool Modify(Module module);}
}

3、接口实例

using Ninesky.Models;
using System.Linq;namespace Ninesky.Areas.Admin.Repository
{/// <summary>/// 模块接口实例/// <remarks>/// 版本v1.0/// 创建2013.12.12/// </remarks>/// </summary>public class ModuleRepository:Ninesky.Repository.ModuleRepository,InterfaceModule{public IQueryable<Module> Find(){return nContext.Modules;}public bool Modify(Module module){nContext.Modules.Attach(module);nContext.Entry<Module>(module).State = System.Data.EntityState.Modified;return nContext.SaveChanges() > 0;}}
}

4、添加控制器ModuleController

首先添加一个实现返回模块列表的action

/// <summary>/// 列表/// </summary>/// <param name="enable">启用状态。【0-全部，1-启用，2-禁用】</param>/// <returns>/// 普通请求时返回包含强类型List\<Module\>的视图<br />/// ajax请求返回json类型List\<Module\>/// </returns>public ActionResult Items(int id = 0){var _modules = moduleRepository.Find();if (Request.IsAjaxRequest()) return Json(_modules);return View(_modules);}

菜单

/// <summary>/// 菜单/// </summary>/// <returns></returns>public ActionResult Menu(){return PartialView(moduleRepository.Find());}

菜单视图

@model IEnumerable<Ninesky.Models.Module>
<div id="westmenu" class="easyui-accordion"><div title="模块列表" class="leftsidebar"><ul>@foreach(var item in Model){<li>@Html.ActionLink(item.Name, "Index", "Module", new { id = item.ModuleId }, new { @class = "westmenuitem" })</li>}</ul></div>
</div>
@*@Scripts.Render("~/Areas/Admin/Scripts/Category.js")*@
<script type="text/javascript">WestMenu();
</script>

模块信息页

/// <summary>/// 模块信息页/// </summary>/// <param name="id"></param>/// <returns></returns>public ActionResult Index(int id){return PartialView(moduleRepository.Find(id));}

@model Ninesky.Models.Module<div class="c_navbar">后台管理 >> 模块管理 >> 模块信息</div>
<div class="easyui-tabs"><div title="基本信息"><div class="fs_wapper">@using (Html.BeginForm("Modify", "Module", FormMethod.Post, new { id = "module_base" })){@Html.AntiForgeryToken()@Html.ValidationSummary(true)<div class="header">@Html.HiddenFor(model => model.ModuleId)</div>@Html.ValidationSummary()<table class="fieldset"><tr><th>@Html.LabelFor(model => model.Name)<span>*</span></th><td>@Html.TextBoxFor(model => model.Name, new { disabled = "disabled" })</td></tr><tr><th>@Html.LabelFor(model => model.Enable)<span>*</span></th><td>@Html.EditorFor(model => model.Enable)@Html.ValidationMessageFor(model => model.Description)</td></tr><tr><th>@Html.LabelFor(model => model.Model)<span>*</span></th><td>@Html.TextBoxFor(model => model.Model, new { disabled = "disabled" })</td></tr><tr><th>@Html.LabelFor(model => model.Description)</th><td>@Html.EditorFor(model => model.Description)@Html.ValidationMessageFor(model => model.Description)</td></tr><tr><th></th><td><a id="btn_modulebase_save" class="easyui-linkbutton">保存</a></tr></table> }@Scripts.Render("~/Areas/Admin/Scripts/Module.js")<script>ModuleBase_Ready();</script></div></div><div title="上传设置">……</div><div title="权限设置">……</div>
</div>

效果图

这里上传设置和权限设置以后补充。

5、控制器中添加启用、关闭模块处理action

/// <summary>/// 修改模块信息/// </summary>/// <returns></returns>public ActionResult Modify(int? ModuleId,bool? Enable,string Description){JsonViewModel _jsonViewModel = new JsonViewModel() { Authentication = 0, Success = true };bool _modifyed = false;if (ModuleId == null) {_jsonViewModel.Success = false;_jsonViewModel.ValidationList.Add("ModuleId", "模块Id不能为空");}if (Enable == null){_jsonViewModel.Success = false;_jsonViewModel.ValidationList.Add("Enable", "启用状态不能为空");}if (_jsonViewModel.Success){var _module = moduleRepository.Find((int)ModuleId);if (_module == null){_jsonViewModel.Success = false;_jsonViewModel.Message = "模块存在";}else{if (_module.Enable != Enable) { _module.Enable = (bool)Enable; _modifyed = true; }if (_module.Description != Description) { _module.Description = Description; _modifyed = true; }if (_modifyed){if (moduleRepository.Modify(_module)) { _jsonViewModel.Success = true; _jsonViewModel.Message = "修改模块成功。"; }else { _jsonViewModel.Success = false; _jsonViewModel.Message = "数据未能保存到数据库"; }}else { _jsonViewModel.Success = false; _jsonViewModel.Message = "数据未发生更改"; }}}else _jsonViewModel.Message = "数据验证失败！";return Json(_jsonViewModel);}

6、模块过滤器

这里写个过滤器，ModuleFilter。命名空间Ninesky.Extensions。作用是加到模块上面，当模块关闭时，前台用户讲不能访问模块内容。

using Ninesky.Repository;
using System.Web.Mvc;namespace Ninesky.Extensions
{/// <summary>/// 模块过滤器/// 屏蔽禁用模块/// <remarks>/// 版本v1.0/// 创建2013.12.12/// </remarks>/// </summary>public class ModuleFilter:ActionFilterAttribute{/// <summary>/// 模型名/// </summary>public string Model { get; set; }public override void OnActionExecuting(ActionExecutingContext filterContext){if (string.IsNullOrEmpty(Model)) filterContext.Result = new ContentResult() { Content = "未指定模块" };switch (Model){case "Article":InterfaceModule _moduleRepository = new ModuleRepository();var _module = _moduleRepository.Find(Model);if (_module == null) filterContext.Result = new ContentResult() { Content = "未找到指定模块" };else if (!_module.Enable) filterContext.Result = new ContentResult() { Content = _module.Name + "已关闭" };break;default:filterContext.Result = new ContentResult() { Content = "未找到指定模块" };break;}}}
}
