Business logic and model parameters in yii?

Question

Yii

Interested in the opinion of how best to build model methods in yii.
There are many examples where they do something like this:

$model->a = $_POST['Model']['a'];
$model->b = $_POST['Model']['a'];
и тд.. либо через массовое присовение $model->attributes = $_POST['Model];
и потом вызов:
$model->create();

Or make input parameters in the create method and work with assigning attributes already inside the method:

$model->create($_POST['Model']['a'],$_POST['Model']['b']);
Внтури уже метод:
function create($a,$b)
{
 $this->a = $a;
 $this->b = $b;
 return $this->save();
}

The second way seems to be more correct because we know exactly what parameters are needed for the method. In the first method, you can't tell right away.
Who is building?

Answer 1

Yii2? Then the ActiveRecord->load()
Yii1 method? ActiveRecord->attributes = $_POST['data']
