And in those cases, we can use classes and inheritance to take advantage of function **type annotations** to get better support in the editor and tools, and still get the FastAPI **data filtering**.

{* ../../docs_src/response_model/tutorial003_01_py310.py hl[7:10,13:14,18] *}

With this, we get tooling support, from editors and mypy as this code is correct in terms of types, but we also get the data filtering from FastAPI.

{* ../../docs_src/response_model/tutorial003_01_py310.py hl[7:10,13:14,18] *}

Com isso, temos suporte de ferramentas, de editores e mypy, pois este código está correto em termos de tipos, mas também obtemos a filtragem de dados do FastAPI.

## Обновление *операции пути* `/token` { #update-the-token-path-operation }

Создайте `timedelta` со временем истечения срока действия токена.

Создайте реальный токен доступа JWT и верните его

### Declarar la dependencia, en el "dependant" { #declare-the-dependency-in-the-dependant }

De la misma forma en que usas `Body`, `Query`, etc. con los parámetros de tu *path operation function*, usa `Depends` con un nuevo parámetro:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

Veja como poderia ser:

{* ../../docs_src/dependencies/tutorial013_an_py310.py *}

O código de saída, o fechamento automático da `Session` em:

{* ../../docs_src/dependencies/tutorial013_an_py310.py ln[19:21] *}

...seria executado depois que a resposta terminar de enviar os dados lentos:

{* ../../docs_src/dependencies/tutorial013_an_py310.py ln[30:38] hl[31:33] *}

## Import `Path` { #import-path }

First, import `Path` from `fastapi`, and import `Annotated`:

/// info

FastAPI added support for `Annotated` (and started recommending it) in version 0.95.0.

If you have an older version, you would get errors when trying to use `Annotated`.
