Y muchos equipos utilizan solo `PUT`, incluso para actualizaciones parciales.

Eres **libre** de usarlos como desees, **FastAPI** no impone ninguna restricción.

Pero esta guía te muestra, más o menos, cómo se pretende que se usen.

///

### Uso del parámetro `exclude_unset` de Pydantic { #using-pydantics-exclude-unset-parameter }

}
```

### Usuario inactivo { #inactive-user }

Ahora prueba con un usuario inactivo, autentícate con:

Usuario: `alice`

Contraseña: `secret2`

Y trata de usar la operación `GET` con la path `/users/me`.

Obtendrás un error de "Usuario inactivo", como:

```JSON
{
  "detail": "Inactive user"
}
```

## Recapitulación { #recap }

burgers = get_burgers(2)
```

---

Así que, si estás usando un paquete que te dice que puedes llamarlo con `await`, necesitas crear las *path operation functions* que lo usen con `async def`, como en:

```Python hl_lines="2-3"
@app.get('/burgers')
async def read_burgers():
    burgers = await get_burgers(2)
    return burgers
```

* **Current predominance**: The majority of existing Gradle code and documentation already uses American English
* **Industry standard**: Most widely used programming languages, frameworks, and tools (Java, Kotlin, JavaScript, etc.) use American English in their APIs and documentation
* **Consistency with dependencies**: Gradle's ecosystem and dependencies predominantly use American English

### Exceptions

it is unlikely that we'll be able to remove `null` entirely.

After migrating to Java 8, we can use pluggable type checkers to ensure that our annotations are consistent, 
and there are no missing null checks.

## Decision

Use "NullAway" in JSpecify mode to check for null-related errors in Java code.

Consider improper uses of `null` detected by NullAway a compilation error (not a warning, and not a separate CI job to test).

## Obtener el usuario { #get-the-user }

`get_current_user` usará una función de utilidad (falsa) que creamos, que toma un token como un `str` y devuelve nuestro modelo de Pydantic `User`:

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## Inyectar al usuario actual { #inject-the-current-user }

        run: |
          git config user.name "github-actions[bot]"
          git config user.email "github-actions[bot]@users.noreply.github.com"
          git add -A
          if git diff --staged --quiet; then
            echo "No changes to commit"
          else
            git commit -m "🎨 Auto format"
            git push
          fi
      - uses: pre-commit-ci/lite-action@v1.1.0

Keep in mind that dataclasses can't do everything Pydantic models can do.

So, you might still need to use Pydantic models.

But if you have a bunch of dataclasses laying around, this is a nice trick to use them to power a web API using FastAPI. 🤓

///

## Dataclasses in `response_model` { #dataclasses-in-response-model }

You can also use `dataclasses` in the `response_model` parameter:

```plaintext
/home/user/code/awesome-project/.venv/bin/python
```

and use that one.

////

//// tab | Windows

```plaintext
C:\Users\user\code\awesome-project\.venv\Scripts;C:\Windows\System32
```

That means that the system will now start looking first for programs in:

```plaintext
C:\Users\user\code\awesome-project\.venv\Scripts
```

   * {@code e1} and {@code e2} in the multiset. If the user attempts to add an element to the
   * multiset that violates this constraint, the {@code add(Object)} call will throw a {@code
   * ClassCastException}.
   *
   * @param comparator the comparator that will be used to sort this multiset. A null value
   *     indicates that the elements' <i>natural ordering</i> should be used.
