```
http://127.0.0.1:8000/items/foo?short=on
```

o

```
http://127.0.0.1:8000/items/foo?short=yes
```

o cualquier otra variación (mayúsculas, primera letra en mayúscula, etc.) tu función verá el parámetro `short` con un valor `bool` de `True`. Si no, lo verá como `False`.

## Múltiples parámetros de path y query

## Fijar la versión de `fastapi`

Lo primero que debes hacer en tu proyecto es "fijar" la última versión específica de **FastAPI** que sabes que funciona bien con tu aplicación.

Por ejemplo, digamos que estás usando la versión `0.45.0` en tu aplicación.

```

</div>

### Paso 3: crea una *operación de path*

#### Path

"Path" aquí se refiere a la última parte de una URL comenzando desde el primer `/`.

Entonces, en una URL como:

```
https://example.com/items/foo
```

...el path sería:

```
/items/foo
```

!!! info "Información"

The idea is to provide a list of suggestions for a problem in the console output.
The suggestions are displayed in the separate "Try"- section of the console output.
The suggestions are collected in the `BuildExceptionReporter` and printed to the console.

In some cases, you still want to keep the old behavior and display the suggestions in the error message.

### Add custom suggestions
