FastAPI usa un **ID único** para cada *path operation*, se usa para el **operation ID** y también para los nombres de cualquier modelo personalizado necesario, para requests o responses.

Puedes personalizar esa función. Toma un `APIRoute` y retorna un string.

Por ejemplo, aquí está usando el primer tag (probablemente tendrás solo un tag) y el nombre de la *path operation* (el nombre de la función).

/// note | Nota

Si no sabes la diferencia, revisa la sección [Async: *"¿Tienes prisa?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

### Paso 5: retorna el contenido

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

Puedes retornar un `dict`, `list`, valores singulares como `str`, `int`, etc.

{* ../../docs_src/path_params/tutorial005.py hl[20] *}

/// tip | Dica



///

	Você também poderia acessar o valor `"lenet"` com `ModelName.lenet.value`

#### Retorne *membros de enumeration*

Você pode retornar *membros de enum* da sua *rota de operação*, em um corpo JSON aninhado (por exemplo um `dict`).

	public final fun getHeaders ()Lokhttp3/Headers;
	public final fun getMethod ()Ljava/lang/String;
	public final fun getRequestLine ()Ljava/lang/String;
	public final fun getTarget ()Ljava/lang/String;
	public final fun getUrl ()Lokhttp3/HttpUrl;
	public final fun getVersion ()Ljava/lang/String;
	public fun toString ()Ljava/lang/String;
}

public abstract interface class mockwebserver3/SocketEffect {
}

Pero si estás seguro de que el contenido que estás devolviendo es **serializable con JSON**, puedes pasarlo directamente a la clase de response y evitar la sobrecarga extra que FastAPI tendría al pasar tu contenido de retorno a través de `jsonable_encoder` antes de pasarlo a la clase de response.
