subversion 主干和分支 合并问题
应用Rails+Ext开发企业级权限平台
一般说来做企业级权限平台都是java的天下,我也不得不认同java这方面的能力。本文介绍的Ext + Rails 开发的企业级权限平台也是在原先用java实现的一套改写而成,保证了基本功能的一致性,UI界面的一致性。这样就充分说明了富客户端框架(或者说RIA)的应用广泛性,能够和多种服务器端语言组合开发应用系统平台。
该平台是基于角色的权限管理后台.集中了一般企业应用所必需包含的必须模块,包括用户维护、模块维护、角色管理、权限管理、数据字典以及统一的页面风格等.由于该开发平台的存在,大大提高了开发人员的开发效率,特别是单表操作,仅仅只需要在范例模块的基础之上进行少量修改即可达到目的.平台架构设计本着追求层次间的低耦合,层次明显分开,TDD开发模式原则进行.
下面有实现的图样~~ (貌似有蛮多 呵呵)
整个开发中没什么新颖的东西 就如同java一般从数据库中去数字组装成符合要求的json字符串输出渲染页面让Ext来显示数据和如何组织项目的结构。
数据库表结构db/schema.rb
字典类型对象和字典对象一对多关系
model/catalog.rb
字典对象
model/dict
组织对象,组织和人员是多对多关系.
model/group.rb
日志对象
model/log.rb
模块对象 模块对象和操作对象都属于资源对象
model/mod.rb

人员角色中间model

人员对象 和组织 角色 资源等关联
model/person.rb
资源对象 包含两种资源 操作和模块
model/resource.rb
角色和资源的关联的中间model
model/role2resource.rb
角色对象 和人员 资源关联
model/role.rb
下面是自己改写过的生成json的插件jsonifier
用于把对象和对象集合转换成符合EXT接受的单个对象的json格式和多个树形结构的json格式
