tp5 数据库迁移工具 migrate&seed

Posted 2020-11-27 yc-l

tp5.0时使用migrate工具，composer安装

composer require topthink/think-migration=1.*

注意，tp5.0对应1版本的migration工具，tp5.1及以上对应2版本的migration工具

查看指令

php think

 

 创建migrate文件(用来建表)

php migrate create:SqUserLogs

在applicaton/database/migrations 文件夹下会创建一个文件 20200318060333_sq_user_logs.php

<?php

use thinkmigrationMigrator;
use thinkmigrationdbColumn;

class SqUserLogs extends Migrator
{
    /**
     * Change Method.
     *
     * Write your reversible migrations using this method.
     *
     * More information on writing migrations is available here:
     * http://docs.phinx.org/en/latest/migrations.html#the-abstractmigration-class
     *
     * The following commands can be used in this method and Phinx will
     * automatically reverse them when rolling back:
     *
     *    createTable
     *    renameTable
     *    addColumn
     *    renameColumn
     *    addIndex
     *    addForeignKey
     *
     * Remember to call "create()" or "update()" and NOT "save()" when working
     * with the Table class.
     */
    public function change()
    {
        $table = $this->table(‘sq_user_logs‘,array(‘engine‘=>‘InnoDB ‘));//InnoDB //MyISAM
        $table ->addColumn(‘uid‘, ‘integer‘, array(‘comment‘=>‘用户在users表中的id‘))       
        ->addColumn(‘access_time‘,‘integer‘,array(‘comment‘=>‘出入时间‘))
        ->addColumn(‘access_status‘,‘boolean‘,array(‘default‘=>0,‘comment‘=>‘出入状态,0表示出门,1表示回家‘))        
        ->addIndex(array(‘id‘), array(‘unique‘=>true))
        ->create();
    }
   /**
    * Migrate Up.
    */
   public function up()
   {
        // 创建表格时
   }

   /**
    * Migrate Down.
    */
   public function down()
   {
        // 删除表格时
   }
}

官方文档不能看了，可以通过源码学习使用，在 项目目录/vendor/topthink/thinkmigration/src/command 中可以找到源码

创建seed文件(用来填充测试数据)

php think seed:create SqUserLogs

在application/database/seeds 文件夹下会创建文件 SqUserLogs.php

<?php


use thinkmigrationSeeder;

class SqUserLogs extends Seeder
{
    /**
     * Run Method.
     *
     * Write your database seeder using this method.
     *
     * More information on writing seeders is available here:
     * http://docs.phinx.org/en/latest/seeding.html
     */
    public function run()
    {
        $data = [
            [1, 1],
            [2, 2],
            [1, 1],
            [3, 2],            
            [1, 1],            
            [2, 2]            
        ];
        foreach($data as $v){
            $this->table(‘sq_user_logs‘)->insert([
                ‘uid‘=>$v[0], ‘access_time‘=>time() + 360, ‘access_status‘=>$v[1]
                ])->save();
        }           
    }
}
