Por exemplo, extendendo o modelo anterior, você poder decidir por ter uma outra chave `importance` no mesmo corpo, além de `item` e `user`.

Se você declará-lo como é, porque é um valor singular, o **FastAPI** assumirá que se trata de um parâmetro de consulta.

Mas você pode instruir o **FastAPI** para tratá-lo como outra chave do corpo usando `Body`:
