How to find out how many rows have changed when updating a laravel 5.6 table?

Question

Laravel

Hello everyone, is it possible to somehow find out some information when working with Laravel ORM, namely:
1. Has the table been updated, that is, the fact of changing at least one field in the table
2. How many fields have been changed
3. Which fields have been changed

Answer 1

1. Has the table been updated, that is, the fact of changing at least one field in the table

Unfortunately, this is the only time I can give an answer. When the table is updated ( https://laravel.ru/docs/v5/eloquent#%D0%B8%D0%B7%D... ) the update_at field is updated. Accordingly, this way you can find out when the update was and whether it was at all.
