`q`가 선택적이지만 값이 주어질 때마다 **값이 50 글자를 초과하지 않게** 강제하려 합니다.

### `Query` 임포트

이를 위해 먼저 `fastapi`에서 `Query`를 임포트합니다:

{* ../../docs_src/query_params_str_validations/tutorial002.py hl[3] *}

## 기본값으로 `Query` 사용

이제 `Query`를 매개변수의 기본값으로 사용하여 `max_length` 매개변수를 50으로 설정합니다:

{* ../../docs_src/query_params_str_validations/tutorial002.py hl[9] *}

기본값 `None`을 `Query(None)`으로 바꿔야 하므로, `Query`의 첫 번째 매개변수는 기본값을 정의하는 것과 같은 목적으로 사용됩니다.

그러므로:

     * Sets up the list condition for querying web authentications.
     *
     * @param cb The condition bean for the query
     * @param webAuthenticationPager The pager containing search criteria
     */
    protected void setupListCondition(final WebAuthenticationCB cb, final WebAuthPager webAuthenticationPager) {
        if (webAuthenticationPager.id != null) {
            cb.query().docMeta().setId_Equal(webAuthenticationPager.id);
