## More information about OpenAPI responses { #more-information-about-openapi-responses }

To see what exactly you can include in the responses, you can check these sections in the OpenAPI specification:

## 0.5.1

* Add section about [helping and getting help with **FastAPI**](https://fastapi.tiangolo.com/help-fastapi/).

* Add note about [path operations order in docs](https://fastapi.tiangolo.com/tutorial/path-params/#order-matters).

 * {@link MapIteratorCache}, this structure caches values for the two most recently retrieved keys.

The examples here use `.dict()` for compatibility with Pydantic v1, but you should use `.model_dump()` instead if you can use Pydantic v2.

### About `**user_in.dict()` { #about-user-in-dict }

#### Pydantic's `.dict()` { #pydantics-dict }

`user_in` is a Pydantic model of class `UserIn`.

Pydantic models have a `.dict()` method that returns a `dict` with the model's data.

## Add extra information { #add-extra-information }

You can declare extra information in `Field`, `Query`, `Body`, etc. And it will be included in the generated JSON Schema.

You will learn more about adding extra information later in the docs, when learning to declare examples.

/// warning

Extra keys passed to `Field` will also be present in the resulting OpenAPI schema for your application.
