数据库迁移工具
数据库迁移工具
首先通过 composer 安装
composer require topthink/think-migration=2.0.*
注意事项,不支持修改文件配置目录
在命令行下运行查看帮助,可以看到新增的命令
php thinkmigratemigrate:create Create a new migrationmigrate:rollback Rollback the last or to a specific migrationmigrate:run Migrate the databasemigrate:status Show migration statusoptimizeoptimize:autoload Optimizes PSR0 and PSR4 packages to be loaded with classmaps too, good for production.optimize:config Build config and common file cache.optimize:route Build route cache.optimize:schema Build database schema cache.seedseed:create Create a new database seederseed:run Run database seeders
创建迁移类,首字母必须为大写
php think migrate:create Users
可以看到目录下有新文件 .\database\migrations\20161117144043_users.php
使用实例
phpuse Phinx\Migration\AbstractMigration;class Users extends AbstractMigration{/*** Change Method.*/public function change(){// create the table$table = $this->table('users',array('engine'=>'MyISAM'));$table->addColumn('username', 'string',array('limit' => 15,'default'=>'','comment'=>'用户名,登陆使用'))->addColumn('password', 'string',array('limit' => 32,'default'=>md5('123456'),'comment'=>'用户密码'))->addColumn('login_status', 'boolean',array('limit' => 1,'default'=>0,'comment'=>'登陆状态'))->addColumn('login_code', 'string',array('limit' => 32,'default'=>0,'comment'=>'排他性登陆标识'))->addColumn('last_login_ip', 'integer',array('limit' => 11,'default'=>0,'comment'=>'最后登录IP'))->addColumn('last_login_time', 'datetime',array('default'=>0,'comment'=>'最后登录时间'))->addColumn('is_delete', 'boolean',array('limit' => 1,'default'=>0,'comment'=>'删除状态,1已删除'))->addIndex(array('username'), array('unique' => true))->create();}/*** Migrate Up.*/public function up(){}/*** Migrate Down.*/public function down(){}}
对于同一个数据表,如果需要新的迁移动作,例如删除字段、创建字段,可以创建新的更改文件,像svn一样往前记录操作,方便回滚。
