我想使用迁移类方法删除表。
这是我的迁移类:
use yii\db\Schema;
use yii\db\Migration;
class m130524_201442_init extends Migration
{
public function up()
{
$tableOptions = null;
if ($this->db->driverName === 'mysql') {
// http://stackoverflow.com/questions/766809/whats-the-difference-between-utf8-general-ci-and-utf8-unicode-ci
$tableOptions = 'CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE=InnoDB';
}
$this->createTable('{{%user}}', [
'id' => Schema::TYPE_PK,
'username' => Schema::TYPE_STRING . ' NOT NULL',
'auth_key' => Schema::TYPE_STRING . '(32) NOT NULL',
'password_hash' => Schema::TYPE_STRING . ' NOT NULL',
'password_reset_token' => Schema::TYPE_STRING,
'email' => Schema::TYPE_STRING . ' NOT NULL',
'firstname' => Schema::TYPE_STRING,
'status' => Schema::TYPE_SMALLINT . ' NOT NULL DEFAULT 10',
'created_at' => Schema::TYPE_INTEGER . ' NOT NULL',
'updated_at' => Schema::TYPE_INTEGER . ' NOT NULL',
], $tableOptions);
}
public function down()
{
$this->dropTable('{{%user}}');
}
}
我使用 yii migrate / to 130524_201442 迁移了此类。之后我做了很多其他的迁移,现在我想删除用户表,所以我尝试了下面的命令,
yii migrate safeDown console\migrations\m130524_201442_init.php
yii migrate down console\migrations\m130524_201442_init.php
输出:
D:\Projects\wamp\www\yiiadvanced>yii migrate down console\migrations\m130524_201442_init.php
Yii Migration Tool (based on Yii v2.0.5)
No new migration found. Your system is up-to-date.
还试过这个:
yii migrate/down 130524_201442
输出
D:\Projects\wamp\www\yiiadvanced>yii migrate/down 130524_201442
Yii Migration Tool (based on Yii v2.0.5)
Total 2 migrations to be reverted:
m151222_063506_roles
m130524_201442_init
Revert the above migrations? (yes|no) [no]:
如果我输入“是”,那么它将还原两个,但我只想删除m130524_201442_init。
那么,我应该使用哪个命令?

试试这个:

}

看来,你运行错误的命令。请显示您收到的错误消息。
在控制台中,转到yii文件所在的目录并尝试:
php yii migrate/to m130524

可能这很难,但对我有用。
