* 👨‍🎨 🐕‍🦺 (🛠️, ♒️), 🐦 🏷

Isso permitiria que você **reutilizasse o modelo** em **diversos lugares**, e também declarasse validações e metadados de todos os parâmetros de uma única vez. 😎

/// note | Nota

Isso é suportado desde o FastAPI versão `0.115.0`. 🤓

///

## Parâmetros de Consulta com um Modelo Pydantic

Declare os **parâmetros de consulta** que você precisa em um **modelo Pydantic**, e então declare o parâmetro como `Query`:

from fastapi.testclient import TestClient

from docs_src.path_operation_advanced_configuration.tutorial004 import app

from ...utils import needs_pydanticv1, needs_pydanticv2

client = TestClient(app)


def test_query_params_str_validations():
    response = client.post("/items/", json={"name": "Foo", "price": 42})
    assert response.status_code == 200, response.text
    assert response.json() == {
        "name": "Foo",
        "price": 42,

## Importe `Path`

Primeiro, importe `Path` de `fastapi`:

//// tab | Python 3.10+

```Python hl_lines="1"
{!> ../../docs_src/path_params_numeric_validations/tutorial001_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="3"

import os
from pathlib import Path

from fastapi.testclient import TestClient

from docs_src.background_tasks.tutorial001 import app

client = TestClient(app)


def test():
    log = Path("log.txt")
    if log.is_file():

# Déploiement

Le déploiement d'une application **FastAPI** est relativement simple.

## Que signifie le déploiement

**Déployer** une application signifie effectuer les étapes nécessaires pour la rendre **disponible pour les
utilisateurs**.

Pour une **API Web**, cela implique normalement de la placer sur une **machine distante**, avec un **programme serveur**
