# path operationデコレータの依存関係

場合によっては*path operation関数*の中で依存関係の戻り値を本当に必要としないこともあります。

もしくは、依存関係が値を返さない場合もあります。

しかし、それでも実行・解決する必要があります。

このような場合、*path operation関数*のパラメータを`Depends`で宣言する代わりに、*path operation decorator*に`dependencies`の`list`を追加することができます。

##  *path operationデコレータ*への`dependencies`の追加

*path operationデコレータ*はオプショナルの引数`dependencies`を受け取ります。

それは`Depends()`の`list`であるべきです:

{* ../../docs_src/dependencies/tutorial006.py hl[17] *}

        p1 = path1.lastIndexOf('/');
        p2 = path2.lastIndexOf('/');
        l1 = path1.length() - p1;
        l2 = path2.length() - p2;

        // anything with dots voids comparison
        if ((l1 > 1 && path1.charAt(p1 + 1) == '.') || (l2 > 1 && path2.charAt(p2 + 1) == '.')) {
            return true;
        }

        return l1 == l2 && path1.regionMatches(true, p1, path2, p2, l1);
    }

        String pathStr = "_1/_2/docid123";
        String expectedDocId = "_1_2docid123";
        String actualDocId = pathStr.replace("/", "").replace("\\", "");
