Yii 2.0 General Discussions

I has set Yii::$app->db and Yii::$app->db2;

I add this code to the migration class

public $db = ‘db2’;

command yii migrate still apply the migration to default database connection which is db, not db2

then i add this to the migration class

protected function getDb()
{
return Yii::$app->db2;
}

still command yii migrate apply to db, not db2

so i need to do command yii migrate --db=db2 to make it work.

I want to just use command yii migrate and db selection determine by the migration class.
