Method Details

`getGroup()` public method #

Returns the field’s group.

public yii\db\ActiveQueryInterface getGroup ( )

return	yii\db\ActiveQueryInterface	The relational query object.

`getOldHandle()` public method #

Returns the old handle.

public string, null getOldHandle ( )

`init()` public method #

Initializes the application component.

public void init ( )

`storeOldHandle()` public method #

Store the old handle.

public void storeOldHandle ( )

`tableName()` public static method #

Declares the name of the database table associated with this AR class.

By default this method returns the class name as the table name by calling \craft\records\Inflector::camel2id() with prefix \craft\records\Connection::tablePrefix. For example if \craft\records\Connection::tablePrefix is tbl_, Customer becomes tbl_customer, and OrderItem becomes tbl_order_item. You may override this method if the table is not named after this convention.

public static string tableName ( )

return	string	The table name
