# Return a Response Directly { #return-a-response-directly }

When you create a **FastAPI** *path operation* you can normally return any data from it: a `dict`, a `list`, a Pydantic model, a database model, etc.

If you declare a [Response Model](../tutorial/response-model.md) FastAPI will use it to serialize the data to JSON, using Pydantic.

Vous pouvez passer à vos décorateurs de *chemin d'accès* un paramètre `responses`.

Il prend comme valeur un `dict` dont les clés sont des codes HTTP pour chaque réponse, comme `200`, et la valeur de ces clés sont d'autres `dict` avec des informations pour chacun d'eux.

Chacun de ces `dict` de réponse peut avoir une clé `model`, contenant un modèle Pydantic, tout comme `response_model`.

## `model` を使った追加レスポンス { #additional-response-with-model }

*path operation デコレータ*に `responses` パラメータを渡せます。

これは `dict` を受け取り、キーは各レスポンスのステータスコード（例: `200`）、値は各レスポンスの情報を含む別の `dict` です。

それぞれのレスポンス `dict` には、`response_model` と同様に Pydantic モデルを格納する `model` キーを含められます。

FastAPI はそのモデルから JSON Schema を生成し、OpenAPI の適切な場所に含めます。

            :param data: Response data for AssumeRoleWithClientGrants request
            :return: dict

            root = STSElement.fromstring(
                'AssumeRoleWithClientGrantsResponse', data)
            result = root.find('AssumeRoleWithClientGrantsResult')
            creds = result.find('Credentials')
            return dict(
                access_key=creds.get_child_text('AccessKeyId'),

### `app.dependency_overrides` Attribute'ünü Kullanın { #use-the-app-dependency-overrides-attribute }

Bu tür durumlar için **FastAPI** uygulamanızda `app.dependency_overrides` adında bir attribute bulunur; bu basit bir `dict`'tir.

Test için bir dependency'yi override etmek istediğinizde, key olarak orijinal dependency'yi (bir function), value olarak da override edecek dependency'nizi (başka bir function) verirsiniz.
