<?php use yii\db\Schema; use yii\db\Migration; class m130524_201442_init extends Migration { public function up() { $tableOptions = null; if ( $this ->db->driverName === ‘mysql‘ ) { $tableOptions = ‘CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE=InnoDB‘ ; } $this ->createTable( ‘{{%user}}‘ , [ ‘id‘ => $this ->primaryKey(), ‘username‘ => $this ->string()->notNull()->unique(), ‘auth_key‘ => $this ->string(32)->notNull(), ‘password_hash‘ => $this ->string()->notNull(), ‘password_reset_token‘ => $this ->string()->unique(), ‘email‘ => $this ->string()->notNull()->unique(), ‘status‘ => $this ->smallInteger()->notNull()->defaultValue(10), ‘created_at‘ => $this ->integer()->notNull(), ‘updated_at‘ => $this ->integer()->notNull(), ], $tableOptions ); } public function down() { $this ->dropTable( ‘{{%user}}‘ ); } } |
用cmd命令行进入advanced目录 ( 该目录下有yii.bat )
执行命令,选yes(输入y)

yii migrate console/migrations/m130524_201442_init.php |
这样就在数据库中新建了一张表user和另一张表migration
其中migration表的内容大致如下,猜想这个version字段和每次执行命令时php文件的名字&文件里的class名有关,所以每次执行命令时需要改动文件名和文件里面的class名
那么,现在新建一张blog表,包含id、title、content、create_time四个字段
先将该php文件复制备份, 再将该文件重命名为m330524_201442_init.php(随机数字,只要和已有的version不同)
再将文件内的class m220524_201442_init extends Migration 中的 220524 改为 330524 (和文件名一样)
编辑字段内容

最后执行命令,选yes

yii migrate console/migrations/m130524_201442_init.php |
可以看到blog表建好了,随机添加两条数据无误
