## Pydantic‑модели для входа и выхода { #pydantic-models-for-input-and-output }

Предположим, у вас есть Pydantic‑модель со значениями по умолчанию, как здесь:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:7] hl[7] *}

### Модель для входа { #model-for-input }

Если использовать эту модель как входную, как здесь:

from typing import Optional, Union

import pytest
from fastapi.openapi.models import Schema, SchemaType


@pytest.mark.parametrize(
    "type_value",
    [
        "array",
        ["string", "null"],
        None,
    ],
)
def test_allowed_schema_type(
    type_value: Optional[Union[SchemaType, list[SchemaType]]],
) -> None:
    """Test that Schema accepts SchemaType, List[SchemaType] and None for type field."""

Melhora o suporte do editor para seus modelos Pydantic com:

* preenchimento automático
* verificação de tipos
* refatoração
* buscas
* inspeções

## Use o modelo { #use-the-model }

Dentro da função, você pode acessar todos os atributos do objeto do modelo diretamente:

# Build state model

The Gradle daemon tracks state for various elements. These are arranged in a hierarchy:

Import `BaseSettings` from Pydantic and create a sub-class, very much like with a Pydantic model.

The same way as with Pydantic models, you declare class attributes with type annotations, and possibly default values.

You can use all the same validation features and tools you use for Pydantic models, like different data types and additional validations with `Field()`.
