角色权限管理组件

角色权限管理：role basic access control，简称rbac。

权限管理:
表：
	用户表
	角色表
	用户角色关系表
	
	菜单表
	权限表
	操作表
	角色权限操作关系表
	
功能：
	- 权限控制
	- 动态菜单

原理：
- 权限控制
	a. 登录时，获取当前用户所有权限，放置在Session中
		request.session['rbac_permission_session_key'] = 'asdf'
		{
			'/index.html': [G,P...]
		}
	b. 其他请求，在session中检测是否具有权限
		中间件 + 配置文件
- 动态菜单
	a. 登录时，获取当前用户菜单和权限，放置在Session中
	
	b. 其他请求，在session中获取菜单，动态生成（simple_tag）

a. 以后调用 

#自定义的中间件加入到settings

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'rbac.middleware.md.RbacMiddleware',    
]

#后端
from rbac import service
  
1. 用户登录后,拿到用户的ID,调用permission_session()函数(函数代码还没写)
   函数获取用户角色的权限,格式如：
   “”“
    user_permission_dict = {
        '/ah-index.html': ["GET","POST","DEL","Edit"],
        '/order.html':  ["GET","POST","DEL","Edit"],
        '/index-(\d+).html':  ["GET","POST","DEL","Edit"],
    }
   ”“”
  
    def login():
    　　permission_session(用户ID,request)
    　　return .....
  
2.setting中加入中间件,如上
　　
  
3.#获取菜单
    current_url= request.pathinfo
    menu_list = service.menu(用户ID，current_url)
  
4.尽量用simple_tag
    css = servicr.css()
    js = servicr.js()
  
5.前端
  
    {{ css|safe }}
    {{ menu_list|safe }}
    {{ js|safe }}

生产环境使用

a. RBAC原理：

原理：
    1. 简单管理
        角色单一，无需使用权限管理

    2. 角色多管理（权限）
        a. 登录
            session放置用户信息（检测是否已经登录）
            session放置权限信息（检测是否有权访问）
                {
                    '/index.html':[GET,EDIT],
                    '/order.html':[GET,EDIT],
                    '/xxx.html':[GET,EDIT...],
                    '/xxx.html':[GET,EDIT...],
                    '/xxx.html':[GET,EDIT...],
                    '/xxx.html':[GET,EDIT...],
                    '/xxx.html':[GET,EDIT...],
                    '/xxx.html':[GET,EDIT...],
                    '/xxx.html':[GET,EDIT...],
                    '/xxx.html':[GET,EDIT...],
                    '/xxx.html':[GET,EDIT...],
                    '/xxx.html':[GET,EDIT...],
                    '/xxx.html':[GET,EDIT...],
                }
                
            session放置菜单权限信息（用于生成动态多级菜单）
            
        b. 访问网站其他功能: http://www.baiuc.om/xxx.hmtl
            - 获取当前访问的URL, request.path_info
            - 
                    /xxx.hmtl?md=get
                匹配1
                    /xxx.hmtl
                    session放置权限信息（检测是否有权访问）
                    {
                        '/index.html':[GET,EDIT],
                        '/order.html':[GET,EDIT],
                        '/xxx.html':[GET,EDIT...],
                    }
                    
                匹配2
                    /xxx.hmtl
                    session放置权限信息（检测是否有权访问）
                    {
                        '/index.html':[GET,EDIT],
                        '/order.html':[GET,EDIT],
                        '/xxx.html':[GET,EDIT...],
                    }
                
                request.permission_code = "EDIT"
                request.permission_code_list = [GET,EDIT...]
                
                
                PS: 中间件实现
                
        c. 视图函数
        
                def xxx(request):
                    request.permission_code = "EDIT"              # 业务逻辑的编写
                    request.permission_code_list = [GET,EDIT...]  # 前端显示功能按钮
                    
        d. 模板
        
        
        e. 创建动态菜单【多级菜单】
                session中获取菜单权限信息（用于生成动态多级菜单）
                    - 当前用户权限
                    - 所有菜单
                1. 权限挂到菜单上
                2. 菜单父子关系处理
                3. 递归生成菜单
                
                辅助：
                    css
                    js
                    
                
                推荐：simple_tag
        
    
    
使用：【详细见README】
    1. 导入rbac
        - 表
        - 中间件
        - service
        - simple_tag
        
    2. 注册app
    
    3. 用户登录
          初始化权限信息： service.initail_permission(request,user_id)
          
          
    4. settings中配置中间件
    
    5. {% rbac_menu reqeust %}
            
        
    其他配置：
        ...
