Class yii\log\DbTarget
Inheritance | yii\log\DbTarget » yii\log\Target » yii\base\Component » yii\base\BaseObject |
---|---|
Implements | yii\base\Configurable |
Available since version | 2.0 |
DbTarget stores log messages in a database table.
The database connection is specified by $db. Database schema could be initialized by applying migration:
yii migrate --migrationPath=@yii/log/migrations/
If you don't want to use migration and need SQL instead, files for all databases are in migrations directory.
You may change the name of the table used to store the data by setting $logTable.
