说一说MVC的MenuCard(五)

1.数据库设计

 1  
 2  create database BookShop
 3  go
 4 
 5  use bookshop
 6  go
 7 
 8 --模块表
 9 create table Module
10 (
11     ModuleID int not null primary key identity(1,1),
12     ModuleName varchar(50) not null  unique,
13     ModuleIcon varchar(20) not null default '',
14 )
15 
16 
17 -- 功能表 Menu
18 create table Menu
19 (
20     MenuID int not null primary key identity(1,1),
21     MenuName varchar(50) not null  unique,
22     MenuIcon varchar(20) not null default '',
23     CtrlName varchar(50) not null, -- 对应的 控制器名称    BookController
24     ModuleID int not null foreign key references Module(ModuleID)  --
25 )
26 
27 -- 方法函数表 Action
28 create table [Action]
29 (
30     ActionID int not null primary key identity(1,1),
31     ActionName varchar(50) not null  unique,
32     ActionIcon varchar(20) not null default '',
33     ActName varchar(50) not null ,    
34     MenuID int not null foreign key references Menu(MenuID)  --
35 )
36 
37 
38 
39 create table [Role]
40 (
41     RoleID int not  null primary key identity(1,1),
42     RoleName varchar(20) not null unique,
43     [Description] varchar(100) not null default '没描述'
44 )
45 
46 create table [User]
47 (
48     UserID int not  null primary key identity(1,1),    
49     LoginName varchar(20) not null unique,        --登录名
50     UserName varchar(20) not null ,        --真实姓名
51     [Password] varchar(20) not null,
52     
53 )
54 
55 
56 create table UserRole  --用户和角色的关系表
57 (
58     RoleID int not null foreign key references [Role](RoleID),
59     UserID int not null foreign key references [User](UserID) 
60 )
61 
62 
63 alter table UserRole
64 add constraint PK_UserRole primary key (RoleID,UserID)
65 
66 go
67 
68 create table RoleAction -- 角色 方法 关系表
69 (
70     RoleID int not null foreign key references [Role](RoleID),
71     ActionID int not null foreign key references [Action](ActionID) 
72 )
73 
74 alter table RoleAction
75 add constraint PK_RoleAction primary key (RoleID,ActionID)

2.实体类

public class ModuleVM
    {
        public ModuleVM()
        {
            menuVms = new List<MenuVm>();
        }
        public string ID { get; set; }
        public string Name { get; set; }
        public List<MenuVm> menuVms { get; set; }
    }
    public class MenuVm
    {
        public MenuVm()
        {
            actions = new List<ActionVm>();
        }
        public int ID { get; set; }
        public string Name { get; set; }
        public string ctrName { get; set; }
        public List<ActionVm> actions { get; set; }
    }
    public class ActionVm
    {
        public int ID { get; set; }
        public string Name { get; set; }

        public string ActName { get; set; }
    }

3.模板页面代码

@using Action= PowerDemo.Models.Action
