我想在创建孩子时自动创建父记录。
例子。
CREATE TABLE IF NOT EXISTS `front_end_users` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`userid` int(11) unsigned NOT NULL,
`tel` varchar(20) NOT NULL,
`addr1` varchar(255) NOT NULL,
`addr2` varchar(255) NOT NULL,
`city` int(11) NOT NULL,
`zip` varchar(10) NOT NULL,
PRIMARY KEY (`id`),
KEY `fk_userid` (`userid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
CREATE TABLE IF NOT EXISTS `users` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`email` varchar(127) NOT NULL,
`username` varchar(32) NOT NULL DEFAULT '',
`password` char(64) NOT NULL,
`logins` int(10) unsigned NOT NULL DEFAULT '0',
`last_login` int(10) unsigned DEFAULT NULL,
`reset_token` char(64) NOT NULL DEFAULT '',
`status` varchar(20) NOT NULL DEFAULT '',
`last_failed_login` datetime NOT NULL,
`failed_login_count` int(11) NOT NULL DEFAULT '0',
`created` datetime NOT NULL,
`modified` datetime NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `uniq_username` (`username`),
UNIQUE KEY `uniq_email` (`email`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=3 ;
CREATE TABLE IF NOT EXISTS `promouter` (
`userid` int(10) unsigned NOT NULL,
`balance` float NOT NULL,
`commision` float NOT NULL,
`mountly_fee` float NOT NULL,
`verified` tinyint(1) NOT NULL DEFAULT '0',
KEY `promouter_ibfk_1` (`userid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
ALTER TABLE `front_end_users`
ADD CONSTRAINT `front_end_users_ibfk_1` FOREIGN KEY (`userid`) REFERENCES `users` (`id`) ON DELETE CASCADE;
ALTER TABLE `promouter`
ADD CONSTRAINT `promouter_ibfk_1` FOREIGN KEY (`userid`) REFERENCES `front_end_users` (`userid`) ON DELETE CASCADE;
users->front_end_users->promouter
如果我promouter
使用登录名、密码和地址创建而不是自动在 users (login, password)
、 front_end_users(addr1, addr2, userid)
和 promouter中插入适当的字段,我想要(userid)
。
我有几个角色。所以我不能将 have_one 添加到用户模型中。但是我将 have_one 添加到 front_end_users 和 promouter 模型中。
