## 正規表現の追加

パラメータが一致するべき<abbr title="正規表現とは、文字列の検索パターンを定義する文字列です。">正規表現</abbr>を定義することができます:

{* ../../docs_src/query_params_str_validations/tutorial004.py hl[11] *}

この特定の正規表現は受け取ったパラメータの値をチェックします:

* `^`: は、これ以降の文字で始まり、これより以前には文字はありません。
* `fixedquery`: は、正確な`fixedquery`を持っています.
* `$`: で終わる場合、`fixedquery`以降には文字はありません.
