1.安装
composer require "robmorgan/phinx
2.执行
php vendor/bin/phinx
直接运行
php vendor/bin/phinx init可生成配置文件
另外一种方法是直接使用php文件做配置文件
使用phinx.php进行配置
#db_config.php
'localhost',
'DB_NAME' => 'lleg',
'DB_USER' => 'root',
'DB_PWD' => '',
);
$settings = $config;
#phinx.php
array(
"migrations" => "db/migrations",
"seeds" => "db/seeds"
),
"environments" => array(
"defaut_migration_table" => "phinxlog",
"default_database" => "lleg",
"default_environment" => "development"
"production" => array(
"adapter" => "mysql",
"host" => $settings["DB_HOST"],
"name" => $settings["DB_NAME"],
"user" => $settings["DB_USER"],
"pass" => $settings["DB_PWD"],
"port" => 3306,
"charset" => "utf8"
),
"development" => array(
"adapter" => "mysql",
"host" => $settings["DB_HOST"],
"name" => $settings["DB_NAME"],
"user" => $settings["DB_USER"],
"pass" => $settings["DB_PWD"],
"port" => 3306,
"charset" => "utf8"
)
)
);
执行 php vendor/bin/phinx status查看连接状态
执行 php vendor/bin/phinx create Migration
现在生成了created /db/migrations/20180310020523_migration.php
编辑这个文件,添加数据库创建内容
public function change()
{
$user = $this->table('user');
$user->addColumn('open_id', 'string', ['limit'=>64]);
$user->addColumn('register_time', 'timestamp', ['default' => 'CURRENT_TIMESTAMP']);
$user->addColumn('favorite_music', 'integer', ['default'=> 0, 'comment'=>'喜欢的音乐']);
$user->addColumn('favorite_vedio', 'integer', ['default'=> 0, 'comment'=>'喜欢的视频数']);
$user->addColumn('favorite_article', 'integer', ['default'=> 0, 'comment'=>'喜欢的文章数']);
$user->addColumn('baby_birthday', 'date', ['null'=>true, 'comment'=>'宝宝生日']);
$user->addColumn('baby_sex', 'boolean', ['null'=>true, 'comment'=>'宝宝性别']);
$user->addColumn('last_login', 'datetime', ['null'=>true, 'comment'=>'最后登陆日期']);
$user->save();
}
默认会添加一个自增id,作为主键
执行 php vendor/bin/phinx migrate
初始化数据
执行 php vendor/bin/phinx seed:create CategorySeeder
系统自动创建 created ./db/seeds/CategorySeeder.php
修改 CategorySeeder.php
执行 php vendor/bin/phinx seed:run 将会进行所有Seed
如果想运行指定的Seed需要用- s参数指定
php vendor/bin/phinx seed:run -s CategorySeeder
更新表结构
当需要更新表结构的时候,需要再创建一个migrate
执行php vendor/bin/phinx create ChangeArtist
再将需要更新的内容写到change函数
public function change()
{
$this->execute('alter table resource drop column artist ;');
$resource = $this->table('resource');
$resource->addColumn('artist', 'string', ['limit'=>128, 'default'=>'']);
$resource->update();
}
最后执行php vendor/bin/phinx migrate
之前的已经执行过的migrate不会执行, 只会执行更新的部分
回滚
php vendor/bin/phinx rollback
说明
以上操作基于Linux操作系统。
在windows中使用phinx.bat文件
D:\workspace_ued\TelegramPostBot (master -> origin)
λ vendor\bin\phinx.bat
