## Criar um modelo de usuário { #create-a-user-model }

Primeiro, vamos criar um modelo de usuário com Pydantic.

Da mesma forma que usamos o Pydantic para declarar corpos, podemos usá-lo em qualquer outro lugar:

{* ../../docs_src/security/tutorial002_an_py310.py hl[5,12:6] *}

## Criar uma dependência `get_current_user` { #create-a-get-current-user-dependency }

Por exemplo, nós podemos definir um modelo `Image`:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[7:9] *}

### Use o sub-modelo como um tipo { #use-the-submodel-as-a-type }

E então podemos usa-lo como o tipo de um atributo:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[18] *}

Isso significa que o **FastAPI** vai esperar um corpo similar à:

```JSON
{
    "name": "Foo",
