인프런 커뮤니티 질문&답변

혹시 기존 테이블 정보가 남아 있다면 삭제한 뒤 다시 시도해보시겠어요?

그래도 오류가 발생하면 아래 가이드를 따라 프로젝트 공유 부탁드립니다.

전체 프로젝트를 압축해서 구글 드라이브로 공유해서 링크를 남겨주세요.
구글 드라이브 업로드 방법은 다음을 참고해주세요.

https://bit.ly/3fX6ygx


업로드시 권한 문제 꼭 확인해주세요
공유 기본 설정은 비공개로 되어 있어 업로드 한 본인 계정만 접근이 가능합니다.

본인 계정이 아닌 링크를 통한 타 계정 접근이 가능한지 확인하는 방법은 업로드 한 구글 계정을 로그아웃하고 링크를 접속하여 "액세스 권한 요청 화면"이 출력되는지 확인을 해주세요.

안녕하세요. 정윤주님, 공식 서포터즈 David입니다.

에러 전문을 올려주시길 요청드립니다.

parent_id는 Category parent에 붙어있는 @JoinColumn 에 의해 생성된 외래키 컬럼이 맞습니다.

감사합니다.
