Is there a way to sort a GridView by attribute that is not a field in the database but a custom-created getter function in the model?
e.x.
class SomeModel extends \yii\mongodb\ActiveRecord {
...
public function getVal() {
return rand(0, 10);
}
And then define sort in Data Provider
...
$provider->sort->defaultOrder = ['val' => SORT_ASC];
doesn’t work
