java.sql.SQLException: Field 'article_id' doesn't have a default value

게시글과 게시글 첨부파일이 OneToMany 관계 속에서 articleAttachment에 Article 객체를 넣어주지 않을 경우, exception 발생

    BigInteger partnerId = securityUser.getUserId();

    Board board = boardRepository.findOneByName(body.getBoardName())
        .orElseThrow(() -> new ApiException(ExceptionEnum.RESOURCE_NOT_FOUND));

    Base user = userRepository.findOneById(partnerId)
        .orElseThrow(() -> new ApiException(ExceptionEnum.RESOURCE_NOT_FOUND));

    Article article = articleMapper.toEntity(body);
    article.setOwner(user);
    article.setBoard(board);

    articleRepository.save(article);

위 코드에서 아래 코드로 변경해주었습니다.

attachment가 article을 알 수 있도록 하는 로직을 추가하니 db에 잘 추가됩니다!

    BigInteger partnerId = securityUser.getUserId();

    Board board = boardRepository.findOneByName(body.getBoardName())
        .orElseThrow(() -> new ApiException(ExceptionEnum.RESOURCE_NOT_FOUND));

    Base user = userRepository.findOneById(partnerId)
        .orElseThrow(() -> new ApiException(ExceptionEnum.RESOURCE_NOT_FOUND));

    Article article = articleMapper.toEntity(body);
    article.setOwner(user);
    article.setBoard(board);

    if (body.getAttachments() != null) {
      article.getAttachments().forEach(a -> a.setArticle(article));
    }
    if (body.getImages() != null) {
      article.getImages().forEach(i -> i.setArticle(article));
    }
    articleRepository.save(article);
