ThinkPhp5 數據遷移(think-migration)

在thinkphp5中提供了數據遷移工具(think-migration),它是機遇phinx開發(文檔地址：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",
];
?>

注意因爲think-migration存放在thinkphp/vendor中 因此在think中須要將vendor加入auoload

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

 

二：命令行運行

 在命令行輸入php think 能夠看見

migrate:數據庫遷移工具 seed:數據庫填充工具

主要討論migrate:

  migrate:create : 建立一個新的數據遷移類,php think migrate:create <file>,文件名須採用駝峯命名法

  forexample:php think migrate:create ScProductImage 文件會在制定目錄下生成一個php文件

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

migrate:run : 完成數據遷移工做 php think migrate:run

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

migrate:status:查看migrate工做狀態 php think migrate:status

 

 

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

  migrate:rollback : 回滾數據到指定的一個數據遷移版本 php think migrate:rollback -t <timeline>

  <timeline> 就是咱們上圖上面紅框表示的值

 

三：migrate文件編寫

     在migrate中有三個方法

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

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

    change:migrate:run 和migrate:rollback時執行 (若是存在該方法 則不會去執行up 與down)
