Class yii\log\DbTarget

继承yii\log\DbTarget » yii\log\Target » yii\base\Component » yii\base\BaseObject
实现yii\base\Configurable
可用自版本2.0
源代码 https://github.com/yiisoft/yii2/blob/master/framework/log/DbTarget.php

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.

属性详情

$db public 属性

The DB connection object or the application component ID of the DB connection. After the DbTarget object is created, if you want to change this property, you should only assign it with a DB connection object. Starting from version 2.0.2, this can also be a configuration array for creating the object.

$logTable public 属性

Name of the DB table to store cache content. Defaults to "log".

public string $logTable '{{%log}}'

方法详情

export() public 方法

Stores log messages to DB.

Starting from version 2.0.14, this method throws LogRuntimeException in case the log can not be exported.

public void export ( )
throws yii\db\Exception
throws yii\log\LogRuntimeException
init() public 方法

Initializes the DbTarget component.

This method will initialize the $db property to make sure it refers to a valid DB connection.

public void init ( )
throws yii\base\InvalidConfigException

if $db is invalid.
