## Імпорт `Field` { #import-field }

Спочатку вам потрібно імпортувати це:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}


/// warning | Попередження

Зверніть увагу, що `Field` імпортується безпосередньо з `pydantic`, а не з `fastapi`, як усе інше (`Query`, `Path`, `Body` тощо).

## Оголошення атрибутів моделі { #declare-model-attributes }

## 匯入 `Field` { #import-field }

首先，你需要匯入它：

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}


/// warning

請注意，`Field` 是直接從 `pydantic` 匯入的，不像其他（如 `Query`、`Path`、`Body` 等）是從 `fastapi` 匯入。

## 宣告模型屬性 { #declare-model-attributes }

接著你可以在模型屬性上使用 `Field`：

## Importe `Field` { #import-field }

Primeiro, você tem que importá-lo:

Note que `Field` é importado diretamente do `pydantic`, não do `fastapi` como todo o resto (`Query`, `Path`, `Body`, etc).
