In those cases, you can use the *path operation decorator* parameter `response_model` instead of the return type.

You can use the `response_model` parameter in any of the *path operations*:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* etc.

### Пріоритет `response_model`

Якщо Ви вказуєте і тип повернення, і `response_model`, то FastAPI використовуватиме `response_model` з пріоритетом.

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:

{* ../../docs_src/dataclasses/tutorial002.py hl[1,7:13,19] *}

The dataclass will be automatically converted to a Pydantic dataclass.

And if you declared a `response_model`, it will still be used to filter and convert the object you returned.

**FastAPI** will use that *temporal* response to extract the status code (also cookies and headers), and will put them in the final response that contains the value you returned, filtered by any `response_model`.

И если вы объявили `response_model`, он всё равно будет использоваться для фильтрации и преобразования возвращаемого объекта.

**FastAPI** будет использовать этот *временный* ответ для извлечения кода состояния (а также cookies и headers) и поместит их в финальный ответ, который содержит возвращаемое вами значение, отфильтрованное любым `response_model`.

## Combining information { #combining-information }

You can also combine response information from multiple places, including the `response_model`, `status_code`, and `responses` parameters.

You can declare a `response_model`, using the default status code `200` (or a custom one if you need), and then declare additional information for that same response in `responses`, directly in the OpenAPI schema.
