  <description>Maven is a project development management and
    comprehension tool. Based on the concept of a project object model:
    builds, dependency management, documentation creation, site
    publication, and distribution publication are all controlled from

But it's there for you if you need it. 🤓

If you want to catch exceptions and create a custom response based on that, create a [Custom Exception Handler](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}.

## Dependencies with `yield` and `except` { #dependencies-with-yield-and-except }

        Element parentElement = root.child(PARENT).orElse(null);
        if (parentElement == null) {
            return false;
        }

        // Apply full inference (parent element trimming based on relativePath)
        return trimParentElementFull(context, root, parentElement, pomMap);
    }

    /**
     * Applies dependency-related inference optimizations.

With SQLModel, we can use **inheritance** to **avoid duplicating** all the fields in all the cases.

#### `HeroBase` - the base class { #herobase-the-base-class }

Let's start with a `HeroBase` model that has all the **fields that are shared** by all the models:

* `name`
* `age`

코드 중복은 버그, 보안 문제, 코드 비동기화 문제(한 곳은 업데이트되었지만 다른 곳은 업데이트되지 않는 문제) 등의 가능성을 증가시킵니다.

그리고 이 모델들은 많은 데이터를 공유하면서 속성 이름과 타입을 중복하고 있습니다.

더 나은 방법이 있습니다.

`UserBase` 모델을 선언하여 다른 모델들의 기본(base)으로 사용할 수 있습니다. 그런 다음 이 모델을 상속받아 속성과 타입 선언(유형 선언, 검증 등)을 상속하는 서브클래스를 만들 수 있습니다.

모든 데이터 변환, 검증, 문서화 등은 정상적으로 작동할 것입니다.

이렇게 하면 각 모델 간의 차이점만 선언할 수 있습니다(평문 `password`가 있는 경우, `hashed_password`만 있는 경우, 혹은 비밀번호가 없는 경우):
