* Автоматическая аннотация и документация.

## Другие типы данных

Ниже перечислены некоторые из дополнительных типов данных, которые вы можете использовать:

* `UUID`:
    * Стандартный "Универсальный уникальный идентификатор", используемый в качестве идентификатора во многих базах данных и системах.
    * В запросах и ответах будет представлен как `str`.
* `datetime.datetime`:

**FastAPI** est basé entièrement sur **Pydantic**.

Vous verrez bien plus d'exemples de son utilisation dans [Tutoriel - Guide utilisateur](tutorial/index.md){.internal-link target=_blank}.

## Les annotations de type dans **FastAPI**

**FastAPI** utilise ces annotations pour faire différentes choses.

 * has exceeded its lifetime and should be refreshed or reloaded.
 */
public class DictionaryExpiredException extends RuntimeException {

    /** Serial version UID for serialization. */
    private static final long serialVersionUID = 1L;

    /**
     * Creates a new instance of DictionaryExpiredException.
     * This constructor initializes the exception to indicate that a dictionary

For example, you cannot put a Pydantic model in a `JSONResponse` without first converting it to a `dict` with all the data types (like `datetime`, `UUID`, etc) converted to JSON-compatible types.

For those cases, you can use the `jsonable_encoder` to convert your data before passing it to a response:

{* ../../docs_src/response_directly/tutorial001.py hl[6:7,21:22] *}

}

// rebalanceAdminStatus holds rebalance status related information exported to mc, console, etc.
type rebalanceAdminStatus struct {
	ID        string                // identifies the ongoing rebalance operation by a uuid
	Pools     []rebalancePoolStatus `json:"pools"` // contains all pools, including inactive
	StoppedAt time.Time             `json:"stoppedAt"`
}

그리고 지금까지와 같은 기능들을 여전히 사용할 수 있습니다.

* 훌륭한 편집기 지원.
* 들어오는 요청의 데이터 변환.
* 응답 데이터의 데이터 변환.
* 데이터 검증.
* 자동 어노테이션과 문서화.

## 다른 데이터 자료형

아래의 추가적인 데이터 자료형을 사용할 수 있습니다:

* `UUID`:
    * 표준 "범용 고유 식별자"로, 많은 데이터베이스와 시스템에서 ID로 사용됩니다.
    * 요청과 응답에서 `str`로 표현됩니다.
* `datetime.datetime`:
    * 파이썬의 `datetime.datetime`.
    * 요청과 응답에서 `2008-09-15T15:53:00+05:00`와 같은 ISO 8601 형식의 `str`로 표현됩니다.

Par exemple, vous ne pouvez pas mettre un modèle Pydantic dans une `JSONResponse` sans d'abord le convertir en un `dict` avec tous les types de données (comme `datetime`, `UUID`, etc.) convertis en types compatibles avec JSON.

Pour ces cas, vous pouvez spécifier un appel à `jsonable_encoder` pour convertir vos données avant de les passer à une réponse :

        # Create fess user if not existing
        if ! id $FESS_USER > /dev/null 2>&1 ; then
            echo -n "Creating $FESS_USER user..."
            useradd --system \
                    -M \
                    --gid "$FESS_GROUP" \
                    --shell /sbin/nologin \
                    --comment "fess user" \
                    -d "$FESS_USER_HOME"  \
                    "$FESS_USER"
            echo " OK"
        fi
