## Importez le `BaseModel` de Pydantic

Commencez par importer la classe `BaseModel` du module `pydantic` :

```Python hl_lines="4"
{!../../../docs_src/body/tutorial001.py!}
```

## Créez votre modèle de données

Déclarez ensuite votre modèle de données en tant que classe qui hérite de `BaseModel`.

Utilisez les types Python standard pour tous les attributs :

    {!> ../../../docs_src/extra_models/tutorial001_py310.py!}
    ```

### Sobre `**user_in.dict()`

#### O `.dict()` do Pydantic

`user_in` é um modelo Pydantic da classe `UserIn`.

Os modelos Pydantic possuem um método `.dict()` que retorna um `dict` com os dados do modelo.

Então, se criarmos um objeto Pydantic `user_in` como:

```Python

### Create Peewee models for our data

Now create the Peewee models (classes) for `User` and `Item`.

This is the same you would do if you followed the Peewee tutorial and updated the models to have the same data as in the SQLAlchemy tutorial.

!!! tip
    Peewee also uses the term "**model**" to refer to these classes and instances that interact with the database.

    Aber erinnern Sie sich, dass, wenn Sie `Query`, `Path`,  `Header` und andere von `fastapi` importieren, diese tatsächlich Funktionen sind, welche spezielle Klassen zurückgeben.

!!! info
    Um Header zu deklarieren, müssen Sie `Header` verwenden, da diese Parameter sonst als Query-Parameter interpretiert werden würden.

## Automatische Konvertierung

Refer to sizing guide for more understanding on default values chosen depending on your erasure stripe size [here](https://github.com/minio/minio/blob/master/docs/distributed/SIZING.md). Parity settings can be changed using [storage classes](https://github.com/minio/minio/tree/master/docs/erasure/storage-class).

### Consistency Guarantees

# `APIRouter`-Klasse

Hier sind die Referenzinformationen für die Klasse `APIRouter` mit all ihren Parametern, Attributen und Methoden.

Sie können die `APIRouter`-Klasse direkt von `fastapi` importieren:

```python
from fastapi import APIRouter
```
