As I undersant I can define additional fields that will be returned by REST-controller with overriding nethod fields in model.
public function fields() {
$fields = parent::fields();
$fields['posts'] = function (User $model)
{
return $model->posts;
};
return $fields;
}
It’s not good when in different actions you need to show different fields, you should use in model code like this:
if (Yii::$app->controller->action->id == 'index') {...}
Is there a better way to implement this feature?
