## 必須にする

これ以上、バリデーションやメタデータを宣言する必要のない場合は、デフォルト値を指定しないだけでクエリパラメータ`q`を必須にすることができます。以下のように:

```Python
q: str
```

以下の代わりに:

```Python
q: Union[str, None] = None
```

現在は以下の例のように`Query`で宣言しています:

```Python
q: Union[str, None] = Query(default=None, min_length=3)
```

そのため、`Query`を使用して必須の値を宣言する必要がある場合は、第一引数に`...`を使用することができます:

```Python hl_lines="7"

                        // known maximally specific, so remove the old maximum.
                        maximal.remove();
                        break;

                    case LESS_SPECIFIC:
                        // This method is less specific than some of the
                        // currently known maximally specific methods, so we

* 만약 매개변수가 **Pydantic 모델** 타입으로 선언되어 있으면, 요청 **본문**으로 해석될 것입니다.

/// note | "참고"

FastAPI는 `q`의 값이 필요없음을 알게 될 것입니다. 기본 값이 `= None`이기 때문입니다.

`Union[str, None]`에 있는 `Union`은 FastAPI에 의해 사용된 것이 아니지만, 편집기로 하여금 더 나은 지원과 에러 탐지를 지원할 것입니다.
