可以像这样来使用：

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",

my_second_user: User = User(**second_user_data)
```

## Bibliothèques GraphQL { #graphql-libraries }

Voici quelques bibliothèques **GraphQL** qui prennent en charge **ASGI**. Vous pouvez les utiliser avec **FastAPI** :

* [Strawberry](https://strawberry.rocks/) 🍓

* Conversion des données pour les données de réponse.
* Validation des données.
* Annotations et documentation automatiques.

## Autres types de données { #other-data-types }

Voici quelques types de données supplémentaires que vous pouvez utiliser :

* `UUID` :
    * Un « identifiant universel unique » standard, couramment utilisé comme ID dans de nombreuses bases de données et systèmes.

Historically, Gradle has shipped with some Groovy types in very prominent APIs.
This required the Kotlin DSL to add special integration to work with Groovy closures.
This has also forced plugins written in languages other than Groovy to use Groovy types for some APIs.

When the Kotlin DSL was introduced, we made an effort to add non-Groovy equivalents for all APIs.

# Модель Pydantic
class User(BaseModel):

```

Далі це можна використовувати так:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

/// tip | Dica

Isso provavelmente não é tão importante ou necessário se você usar `Annotated`.

///

Vamos supor que você queira declarar o parâmetro de consulta `q` como uma `str` obrigatória.

E você não precisa declarar mais nada para esse parâmetro, então você realmente não precisa usar `Query`.

Mas você ainda precisa usar `Path` para o parâmetro de path `item_id`. E você não quer usar `Annotated` por algum motivo.
