### Modelo para Entrada { #model-for-input }

Si usas este modelo como entrada, como aquí:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

...entonces el campo `description` **no será requerido**. Porque tiene un valor por defecto de `None`.

### Modelo de Entrada en la Documentación { #input-model-in-docs }

### Modelo para Entrada { #model-for-input }

Se você usar esse modelo como entrada, como aqui:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

... então o campo `description` **não será obrigatório**. Porque ele tem um valor padrão de `None`.

Dentro de tu *path operation function*, pasa tu función de tarea al objeto de *background tasks* con el método `.add_task()`:

{* ../../docs_src/background_tasks/tutorial001_py39.py hl[14] *}

`.add_task()` recibe como argumentos:

* Una función de tarea para ejecutar en segundo plano (`write_notification`).
* Cualquier secuencia de argumentos que deba pasarse a la función de tarea en orden (`email`).

### Model for Input { #model-for-input }

If you use this model as an input like here:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

...then the `description` field will **not be required**. Because it has a default value of `None`.

### Input Model in Docs { #input-model-in-docs }

* А также может быть объявление модели ответа, например `response_model=InvoiceEventReceived`.

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[14:16,19:20,26:30] *}

Есть 2 основных отличия от обычной *операции пути*:

## File Parameters with `UploadFile` { #file-parameters-with-uploadfile }

Define a file parameter with a type of `UploadFile`:

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[14] *}

Using `UploadFile` has several advantages over `bytes`:

* You don't have to use `File()` in the default value of the parameter.
* It uses a "spooled" file:
