PHP 클래스 Prado\Data\ActiveRecord\Relations\TActiveRecordBelongsTo

+------+ +--------+ | Team | 1 <----- * | Player | +------+ +--------+ Where one team may have 0 or more players and each player belongs to only one team. We may model Team-Player object relationship as active record as follows. class TeamRecord extends TActiveRecord { see TActiveRecordHasMany for detailed definition. } class PlayerRecord extends TActiveRecord { const TABLE='player'; public $player_id; //primary key public $team_name; //foreign key player.team_name <-> team.name public $age; public $team; //foreign object TeamRecord public static $RELATIONS = array ( 'team' => array(self::BELONGS_TO, 'TeamRecord') ); public static function finder($className=__CLASS__) { return parent::finder($className); } } The static $RELATIONS property of PlayerRecord defines that the property $team belongs to a TeamRecord. The team object may be fetched as follows. $players = PlayerRecord::finder()->with_team()->findAll(); The method with_xxx() (where xxx is the relationship property name, in this case, team) fetchs the corresponding TeamRecords using a second query (not by using a join). The with_xxx() accepts the same arguments as other finder methods of TActiveRecord, e.g. with_team('location = ?', 'Madrid'). 파일 보기 프로젝트 열기: pradosoft/prado
