YII2 how to get old model values?

Question

Yii

When editing data, there are two fields that store paths to files. If the user does not change the files, then the data is empty, but they already exist in the model, is it possible to get them? There is no desire to make another request))

Answer 1

It won't fit?

public function afterSave($insert, $changedAttributes)
{
        var_dump($changedAttributes['desabilitado']);
        var_dump($this['desabilitado']);
        die;
        [...]
}

Write for what you need to use.
