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;
}
}
}
}
