## Pydantic 모델

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>은 데이터 검증(Validation)을 위한 파이썬 라이브러리입니다.

당신은 속성들을 포함한 클래스 형태로 "모양(shape)"을 선언할 수 있습니다.

그리고 각 속성은 타입을 가지고 있습니다.

Додаткові ключі, передані в `Field`, також будуть присутні у згенерованій схемі OpenAPI для вашого додатка.
Оскільки ці ключі не обов'язково можуть бути частиною специфікації OpenAPI, деякі інструменти OpenAPI, наприклад, [OpenAPI валідатор](https://validator.swagger.io/), можуть не працювати з вашою згенерованою схемою.

///

## Підсумок

Ви можете використовувати `Field` з Pydantic для визначення додаткових перевірок та метаданих для атрибутів моделі.

For example, if the client tries to send a `tool` query parameter with a value of `plumbus`, like:

```http
https://example.com/items/?limit=10&tool=plumbus
```

They will receive an **error** response telling them that the query parameter `tool` is not allowed:

```json
{
    "detail": [
        {

 * occurrences of an element are removed, after which that element is added to the multiset, the
 * element will appear at the end of the iteration.
