php - Retrieve the child model of a record in Yii Framework -

i trying understand how model child class of cactiverecord model.

i have following 2 basic classes:

• class user extending cactiverecord
• class tutor extending user

the connection between them id of table users being fk in table tutors. in current app instanciating user class, need data tutor.

the relations set gii follows:

for user class: public function relations()     {         return array(             'tutor' => array(self::has_many, 'tutors', 'user_id'),         );     }   tutor class: public function relations() {     return array(         'user' => array(self::belongs_to, 'users', 'user_id'),     ); } 

how can can object populated data both models?

note: database tables named @ plural, while models @ singular.

when query active record model should bring in related objects automatically (provided have set relationships properly). following give start.

$users=user::model()->findall(); 

depending on doing data need decide if wish lazily fetch related tables or eagerly fetch them. following eagerly fetch records.

$users=user::model()->with('tutor')->findall(); 

the yii documentation on subject , worth read: http://www.yiiframework.com/doc/guide/1.1/en/database.arr#performing-relational-query
