# 依存関係としてのクラス

**依存性注入** システムを深く掘り下げる前に、先ほどの例をアップグレードしてみましょう。

## 前の例の`dict`

前の例では、依存関係（"dependable"）から`dict`を返していました:

```Python hl_lines="9"
{!../../docs_src/dependencies/tutorial001.py!}
```

しかし、*path operation関数*のパラメータ`commons`に`dict`が含まれています。

また、エディタは`dict`のキーと値の型を知ることができないため、多くのサポート（補完のような）を提供することができません。

もっとうまくやれるはずです...。

## 依存関係を作るもの

これまでは、依存関係が関数として宣言されているのを見てきました。

/// note | "Technical Details"

A `Request` has a `request.scope` attribute, that's just a Python `dict` containing the metadata related to the request.

A `Request` also has a `request.receive`, that's a function to "receive" the body of the request.

The `scope` `dict` and `receive` function are both part of the ASGI specification.

Em seguida, você pode retornar qualquer objeto que precise, como normalmente faria (um `dict`, um modelo de banco de dados, etc).

E se você declarou um `response_model`, ele ainda será usado para filtrar e converter o objeto que você retornou.
