# How To - Recipes { #how-to-recipes }

Here you will see different recipes or "how to" guides for **several topics**.

Most of these ideas would be more or less **independent**, and in most cases you should only need to study them if they apply directly to **your project**.

If something seems interesting and useful to your project, go ahead and check it, but otherwise, you might probably just skip them.

## Retornando uma `Response` personalizada { #returning-a-custom-response }

O exemplo acima mostra todas as partes que você precisa, mas ainda não é muito útil, já que você poderia ter retornado o `item` diretamente, e o **FastAPI** colocaria em uma `JSONResponse` para você, convertendo em um `dict`, etc. Tudo isso por padrão.

        Filing feature requests is one of the most popular ways to contribute to Guava.


        Be aware, though: most feature requests are not accepted, even if they're suggested by
        a full-time Guava team member. [Feedback](https://stackoverflow.com/a/4543114) from our

Mas isso significa que, se você simplesmente convertê-lo para uma string e retornar essa informação diretamente, você pode acabar vazando um pouco de informação sobre o seu sistema; por isso, aqui o código extrai e mostra cada erro de forma independente.

You can change/extend these stubs, and tests should not be breaking too much, since most tests
assert using expected values from the stubs. Normally, when you try to use data from the stubs that
have not been properly populated, you'll get a nullpointer in your test and you then have to
identify which stub creates that specific piece of data.

The most important stubs are:
