## Атрибуты, содержащие списки подмоделей

Вы также можете использовать модели Pydantic в качестве типов вложенных  в `list`, `set` и т.д:

{* ../../docs_src/body_nested_models/tutorial006_py310.py hl[18] *}

Такая реализация будет ожидать (конвертировать, валидировать, документировать и т.д) JSON-содержимое в следующем формате:

```JSON hl_lines="11"

/// warning

You can declare multiple `File` and `Form` parameters in a *path operation*, but you can't also declare `Body` fields that you expect to receive as JSON, as the request will have the body encoded using `multipart/form-data` instead of `application/json`.

This is not a limitation of **FastAPI**, it's part of the HTTP protocol.

Mas, por enquanto, vamos nos concentrar nos detalhes específicos de que precisamos.

///

{* ../../docs_src/security/tutorial003_an_py310.py hl[87] *}

/// tip | Dica

Pela especificação, você deve retornar um JSON com um `access_token` e um `token_type`, o mesmo que neste exemplo.

But for the generated client, we could **modify** the OpenAPI operation IDs right before generating the clients, just to make those method names nicer and **cleaner**.

We could download the OpenAPI JSON to a file `openapi.json` and then we could **remove that prefixed tag** with a script like this:

{* ../../docs_src/generate_clients/tutorial004.py *}

//// tab | Node.js

```Javascript

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image02.png">
</div>

Das bedeutet, dass es **immer einen Wert** hat, der Wert kann jedoch manchmal `None` sein (oder `null` in JSON).

#!/usr/bin/env bash

echo "script failed" >resiliency-verify-healing.log # assume initial state

# Extract arguments from json object ...
FILE=$(echo $1 | jq -r '.args.file')
DIR=$(echo $1 | jq -r '.args.dir')
DEEP=$(echo $1 | jq -r '.args.deep')
WANT=$(echo $1 | jq 'del(.args)') # ... and remove args from wanted result

ALIAS_NAME=myminio
BUCKET="test-bucket"

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

Eles serão convertidos para o seus valores correspondentes (strings nesse caso) antes de serem retornados ao cliente:

{* ../../docs_src/path_params/tutorial005.py hl[18,21,23] *}

No seu cliente você vai obter uma resposta JSON como:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}

İç içe geçen derin modelleri pek iyi işleyemiyor. Yani eğer istekteki JSON gövdesi derin bir JSON objesiyse düzgün bir şekilde dökümante edilip doğrulanamıyor.
