수업에서는 product 테이블을 생성할 때 연관된 테이블의 데이터도 한번에 만들 수 있도록 구현하였습니다.그렇다면 데이터 수정도 product의 mutation 요청으로 연관 테이블들의 데이터도 모두 수정할 수 있도록 구현해야 하나요?이렇게 하려니 product 업데이트를 위해 입력해야 하는 데이터가 너무 많아지고 연관된 테이블의 데이터를 수정하는 경우에 create처럼 연관된 테이블의 컬럼의 데이터를 하나하나 다시 다 지정해줘야 하는 불편함도 있습니다.이렇게 한방에 처리하는거 말고 일단 product update mutation에는 product의 본래 컬럼들만 수정할 수 있도록 처리하고 연관된 테이블의 데이터는 연관 테이블의 기본키로 해당 테이블들의 update mutation으로 처리해도 될까요? 일단은 연관된 테이블의 기본키를 product의 fetchProduct로 조회하고 찾은 키를 이용해서 연관 테이블의 데이터를 수정하는 방식입니다.어떤 구조가 올바른 방식일까요?

  포트포워딩으로 외부에서 db에 접속가능하게끔 포트 뚫어주고 테스트 해봤습니다. build한뒤 start 했을때 해당 local db에 데이터 삽입 되는거 까지 확인했고 폰으로 와이파이 연결끊고 접속도 해서 적용되는것 또한 테스트 해봤습니다. 하지만 vercel에서 배포를 하게되면 요청은 처리 되지만 Application error: a client-side exception has occurred (see the browser console for more information). 해당 오류가 발생하게 되네요.prisma + mysql db 사용중입니다. env 설정, axios url까지 다 맞는데 왜 안되는걸까요...? vercel postgre beta 버전으로 연동하면은 되기는 하지만 저는 local db에 연결해서 배포를 하고 싶습니다. 하지만 찾아봐도 vercel이랑 db 연동하는 방법은 잘 나오지않네요.
