实现简单的ACL 博客分类： FleaPHP/QEEPHP 资料

终于写完了 呵呵 简单的一个实现

-- ACL Tables

-- 表的结构 `aclresources`
DROP TABLE IF EXISTS `aclresources`;
CREATE TABLE IF NOT EXISTS `aclresources` (
  `rsid` varchar(64) NOT NULL ,
  `access` int(4) NOT NULL default 0,  
  `desc` varchar(240) NOT NULL default '',
  `created_at` int(10) unsigned NOT NULL default 1,
  `updated_at` int(10) unsigned NOT NULL default 0,
  PRIMARY KEY  (`rsid`)
)DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

-- 表的结构 `aclroles`
DROP TABLE IF EXISTS `aclroles`;
CREATE TABLE IF NOT EXISTS `aclroles` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `rolename` varchar(32) NOT NULL ,
  `durces_aclroles` (
  `rsid` varchar(64) NOT NULL ,
  `role_id` int(10) unsigned NOT NULL ,
  PRIMARY KEY  (`rsid`,`role_id`)
)DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

-- 表的结构 `ref_users_aclroles`
DROP TABLE IF EXISTS `ref_users_aclroles`;
CREATE TABLE IF NOT EXISTS `ref_users_aclroles` (
  `user_id` int(10) unsigned NOT NULL auto_increment,
  `role_id` int(10) unsigned NOT NULL ,
  PRIMARY KEY  (`user_id`,`role_id`)
)DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

-- 表的结构 `users`
DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `email` varchar(128) NOT NULL,
  `password` varchar(64) NOT NULL,
  `nickname` varchar(32) NOT NULL default '',
  `roles` varchar(240) NOT NULL default '',
  `created_at` int(10) unsigned NOT NULL default 1,
  `updated_at` int(10) unsigned NOT NULL default 0,
  PRIMARY KEY  (`id`),
  UNIQUE KEY `user_email` (`email`)
)DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
