Get DISTINCT value from related model

Question

I have 2 models. Users and Ips . Users relation :

return array(
    'ips' => [self::HAS_MANY, 'Ips', ['user_id' => 'id']]
);

Ips model has fields id, user_id, ip .

I need to get all Users with its unique Ips .

$users = $model->with(['ips' => [
    'select' => 'ip', 
    'distinct' => true
]])->findAll();

doesn`t work the way I need. Probably it gets unique by field id .

Thanks for response!

Answer 1

尝试像这样定义您的关系：

return array( 'ips' => [self::HAS_MANY, 'Ips', 'user_id'] );

Answer 2

You may want to try GROUP BY

$users = User::model()->with(array(
    'ips'=>array(
        'group'=>'user_id, ip',
    )
))->findAll();

Hope it helps
