原文:构建ASP.NET MVC4+EF5+EasyUI+Unity2.x注入的后台管理系统（22）-权限管理系统-模块导航制作

最近比较忙，系统难度独步增加，文章的发布速度明显比以前慢了。

由于我们已经跑通了整个系统，所有东西都回到了简单，接下来我们做模块制作也就是操作SysModule表。

首先我们来回顾一下之前的难点主要就是SysRight这个表Rightflag字段的改变，这个字段关系导航与角色组的关系显示（即有权限时候显示菜单导航,这个更新讲到授权讲到，在这里浮头一下）

所以我们操作SysModule必须更新SysRight这张表,把模块先分配给角色

所以思路已经比较明显和简单了，这里我们模块将用treegrid来做，同时也间接学习怎么用treegrid，我之前也没用过easyui的datagrid，系统是jqgrid

这里用到权限控制了，所以你必须为SysModule添加增加，删除，修改等权限，并为admin用户授权，添加权限跳转到第十八讲 （必须非常熟练这一步，多用手动插入数据）

在此之前，由于我之前没用过treegrid不知道有个字段state（展开或者关闭属性）与数据库表SysModule的state字段冲突。然后更新EF

所以我们要修改一下SysModule的State变成Enable

添加后，我们依旧添加SysModule和SysModuleOperate模块的DAL BLL Model层代码（老套路了）

CreateOpt.cshtml

创建模块的DAL层用到了一个存储过程，这个存储过程就是分配模块给角色的，要添加到EF

USE [AppDB]
GO
/****** Object:  StoredProcedure [dbo].[P_Sys_InsertSysRight]    Script Date: 12/24/2013 23:10:18 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
Create proc [dbo].[P_Sys_InsertSysRight]
as
--将设置好的模块分配到角色组
    insert into SysRight(Id,ModuleId,RoleId,Rightflag)
        select distinct b.Id+a.Id,a.Id,b.Id, from SysModule a,SysRole b
        where a.Id+b.Id not in(select ModuleId+RoleId from SysRight)

P_Sys_InsertSysRight

后面补充一个存储过程,这个存储过程执行了清除无用的SysRightOperate(当每次删除角色或者模块,或者操作码时候会产生的垃圾),当然不清楚也不会对系统造成任何影响

Create proc [dbo].[P_Sys_ClearUnusedRightOperate]
as
--清理权限中的无用项目
delete from SysRightOperate where Id not in(
    select a.RoleId+a.ModuleId+b.KeyCode from SysRight a,SysModuleOperate b
        where a.ModuleId = b.ModuleId
)
GO

P_Sys_ClearUnusedRightOperate

最后大家别忘记要注入！！！一个丑陋的界面就这样完成了，大家自己动手美化一下吧.

本节演示了Easyui制作菜单，即无限级别树的做法，以及DataGrid之间的联动，我也是和大家一起学习，我也是Easyui的新手，如有不足，请大家见谅
