yii active record delete by composite primary key mysql

Question

I have table with composite primary key ('service_id', 'action_id'). This table was implemented as many2many relationship between action and service.

I can delete some record in another table by simple primary key like that:

ModelClass::model()->deleteByPk( 5 );

How can I delete record with composite primary key?

ModelClass::model()->deleteByPk( ? );

Answer 1

See docs

For one record:

ModelClass::model()->deleteByPk(array('service_id'=>xxxx,'action_id'=>yyyy));

For multiple records:

ModelClass::model()->deleteByPk(array(
  array('service_id'=>xxxx,'action_id'=>yyyy),
  array('service_id'=>xxxx,'action_id'=>zzzz),
  array('service_id'=>mmmm,'action_id'=>nnnn),
));

Answer 2

将元素作为键传递给数组

ModelClass::model()->deleteByPk(array('service_id'=>'value','action_id'=>'value'));
