Y si declaraste un `response_model`, todavía se utilizará para filtrar y convertir el objeto que devolviste.

**FastAPI** usará ese response *temporal* para extraer el código de estado (también cookies y headers), y los pondrá en el response final que contiene el valor que devolviste, filtrado por cualquier `response_model`.

Podrías **desplegar un servidor** tú mismo utilizando una combinación de herramientas, podrías usar un **servicio en la nube** que hace parte del trabajo por ti, u otras opciones posibles.

There is also an **Advanced User Guide** that you can read later after this **Tutorial - User guide**.

The **Advanced User Guide** builds on this one, uses the same concepts, and teaches you some extra features.

But you should first read the **Tutorial - User Guide** (what you are reading right now).

FastAPI supports dependencies that do some <abbr title='sometimes also called "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code", etc.'>extra steps after finishing</abbr>.

To do this, use `yield` instead of `return`, and write the extra steps (code) after.

/// tip

Make sure to use `yield` one single time per dependency.
