如果你想要在函数内重载响应，但是同时在 OpenAPI 中文档化「媒体类型」，你可以使用 `response_class` 参数并返回一个 `Response` 对象。

接着 `response_class` 参数只会被用来文档化 OpenAPI 的 *路径操作*，你的 `Response` 用来返回响应。

#### 直接返回 `HTMLResponse` { #return-an-htmlresponse-directly }

比如像这样：

{* ../../docs_src/custom_response/tutorial004_py310.py hl[7,21,23] *}

在这个例子中，函数 `generate_html_response()` 已经生成并返回 `Response` 对象而不是在 `str` 中返回 HTML。

## Une application avec des callbacks { #an-app-with-callbacks }

Voyons tout cela avec un exemple.

Imaginez que vous développiez une application qui permet de créer des factures.

Ces factures auront un `id`, un `title` (facultatif), un `customer` et un `total`.

    SQLModel, `str` olarak tanımlanan bir şeyin SQL tarafında `TEXT` (veya veritabanına bağlı olarak `VARCHAR`) tipinde bir sütun olacağını bilir.

### Engine Oluşturma { #create-an-engine }

Bir SQLModel `engine`’i (altta aslında bir SQLAlchemy `engine`’idir) veritabanına olan **bağlantıları tutan** yapıdır.

Tüm kodunuzun aynı veritabanına bağlanması için **tek bir `engine` nesnesi** kullanırsınız.
