Can I have a more detailed explanation with examples? For comparison, there are method hasChanged()

i mean is log activity action
when i insert data it wil insert and save to my log table
and when i update data it will just save updated data ex: i have field username - name and i change the name so the update will compare old value and new value any change will like this {"from" => 'oldvalue', 'to' => 'newvalue'}

sorry my english is bad

Before updating, check the changed properties of the entity and save somewhere (log, other table)

PHP Code:

<?php

// Controller, Something like this
$entity = $model->get(15);
$entity->setText('new text');

if ($entity->hasChanged('text')) {
    // save to log, table
}

$model->update($entity, 'id');
