* It also declares an optional `last_query` cookie, as a `str`.
    * If the user didn't provide any query `q`, we use the last query used, which we saved to a cookie before.

## Use the dependency

Then we can use the dependency with:

=== "Python 3.10+"

    ```Python hl_lines="23"
    {!> ../../../docs_src/dependencies/tutorial005_an_py310.py!}

    "price": 3,
    "description": None,
}
```

because it doesn't include the already stored attribute `"tax": 20.2`, the input model would take the default value of `"tax": 10.5`.

And the data would be saved with that "new" `tax` of `10.5`.

## Partial updates with `PATCH`

                                    }
                                }
                            },
                        },
                    },
                    "summary": "Save Union Body",
                    "operationId": "save_union_body_items__post",
                    "requestBody": {
                        "content": {
                            "application/json": {
                                "schema": {

## Épinglez votre version de `fastapi`

Tout d'abord il faut "épingler" la version de **FastAPI** que vous utilisez à la dernière version dont vous savez
qu'elle fonctionne correctement pour votre application.

Par exemple, disons que vous utilisez la version `0.45.0` dans votre application.

## Pydantic

Toute la validation de données est effectué en arrière-plan avec <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>,
dont vous bénéficierez de tous les avantages. Vous savez donc que vous êtes entre de bonnes mains.

## L'ordre importe

Quand vous créez des *fonctions de chemins*, vous pouvez vous retrouver dans une situation où vous avez un chemin fixe.

#### Install `openapi-ts`

You can install `openapi-ts` in your frontend code with:

<div class="termy">

```console
$ npm install @hey-api/openapi-ts --save-dev

---> 100%
```

</div>

#### Generate Client Code

To generate the client code you can use the command line application `openapi-ts` that would now be installed.
