If you need to do any type of validation that requires communicating with any **external component**, like a database or another API, you should instead use **FastAPI Dependencies**, you will learn about them later.

These custom validators are for things that can be checked with **only** the **same data** provided in the request.

Then for any subsequent call of `get_settings()` in the dependencies for the next requests, instead of executing the internal code of `get_settings()` and creating a new `Settings` object, it will return the same object that was returned on the first call, again and again.

Якщо Вам потрібно виконати будь-яку валідацію, яка вимагає взаємодії з будь-яким **зовнішнім компонентом**, таким як база даних чи інший API, ви повинні замість цього використовувати **FastAPI Dependencies**. Ви дізнаєтесь про них пізніше.

Ці кастомні валідатори використовуються для речей, які можна перевірити лише з **тими даними**, що надані в запиті.
