ThinkPhp5 数据迁移(think-migration)

在thinkphp5中提供了数据迁移工具(think-migration),它是机遇phinx开发(文档地址：http://docs.phinx.org/en/latest/)

一：配置think-migration

在commond.php 中添加

<?php
return [
    "think\\migration\\command\\migrate\\Create",
    "think\\migration\\command\\migrate\\Run",
    "think\\migration\\command\\migrate\\Rollback",
    "think\\migration\\command\\migrate\\Status",
    "think\\migration\\command\\seed\\Create",
    "think\\migration\\command\\seed\\Run",
];
?>

注意由于think-migration存放在thinkphp/vendor中 所以在think中需要将vendor加入auoload

require __DIR__.‘/../thinkphp/vendor/autoload.php‘;

二：命令行运行

 在命令行输入php think 可以看见

migrate:数据库迁移工具 seed:数据库填充工具

主要讨论migrate:

  migrate:create : 创建一个新的数据迁移类,php think migrate:create <file>,文件名须采用驼峰命名法

  forexample:php think migrate:create ScProductImage 文件会在制定目录下生成一个php文件

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

migrate:run : 完成数据迁移工作 php think migrate:run

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

migrate:status:查看migrate工作状态 php think migrate:status

***********************************************************************************************

  migrate:rollback : 回滚数据到指定的一个数据迁移版本 php think migrate:rollback -t <timeline>

  <timeline> 就是我们上图上面红框表示的值

三：migrate文件编写

     在migrate中有三个方法

     up:在migrate:run时执行(前提是文件中不存在change方法)

    down:在migrate:rollback时执行(前提是文件中不存在change方法)

    change:migrate:run 和migrate:rollback时执行 (如果存在该方法 则不会去执行up 与down)
