**FastAPI** はそれらを解決してくれます。

## 最初の依存関係「依存可能なもの」 { #first-dependency-dependable }

以下のような最初の依存関係（「依存可能なもの」）を作成することができます:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

これはオプショナルのクエリパラメータ`q`を`str`として宣言し、それを返すだけです。

これは非常にシンプルです（あまり便利ではありません）が、サブ依存関係がどのように機能するかに焦点を当てるのに役立ちます。

## 第二の依存関係 「依存可能なもの」と「依存」 { #second-dependency-dependable-and-dependant }

Şimdi dependency’lerimizi güncelleyeceğiz.

`current_user`’ı *sadece* kullanıcı aktifse almak istiyoruz.

Bu yüzden, `get_current_user`’ı dependency olarak kullanan ek bir dependency olan `get_current_active_user`’ı oluşturuyoruz.

Bu iki dependency de kullanıcı yoksa veya pasifse sadece HTTP hatası döndürecek.
