How to update only the data that came in yii?

Question

Yii

Data comes from the form, how to update only the data that came?
is there something like $model->updateByPk($id, $model->attributes) ? (it is not an option to prescribe each field, because if it is empty, then emptiness is filled)

Answer 1

solution in the forehead: before saving, get the record from the database, do a diff, do an update. This method uses Doctrine by default unless otherwise specified.
you can also make logic based on __get / __set methods to track changes in data ...
