[리뉴얼] 타입스크립트 올인원 : Part1. 기본 문법편

안녕하세요. 좋은 강좌 감사합니다. const enum EDirection { Up, Down, Left, Right, } const ODirection = { Up: 0, Down: 1, Left: 2, Right: 3, } as const; EDirection.Up; (enum member) EDirection.Up = 0 ODirection.Up; (property) Up: 0 // Using the enum as a parameter function walk(dir: EDirection) {} // It requires an extra line to pull out the keys type Direction = typeof ODirection[keyof typeof ODirection]; function run(dir: Direction) {} walk(EDirection.Left); run(ODirection.Right); 강의안에 있는 위의 예시를 실행해 보았는데요 마지막 줄에 walk(8); 을 실행하면 에러가 나지 않고 run(8); 은 에러가 나는 이유가 무엇일까요? 또 walk(Edirection.bottom); 이라고 실행하면 에러가 나던데 완전히 Edirection 안의 값과는 다른 8이라는 값을 넣었는데 에러가 안 나는 것이 이해가 안 됩니다.

안녕하세요. 강의 잘 듣고 있습니다. service에 @Transactional public ResponseDTO changeAuthority(String invitedId, UserAuthority authority, Long companyId, String sessionUserId, Locale locale) { Users user = usersRepository.findByUserIdAndCompanyAndUseYn(invitedId, new Company(companyId), "Y"); user.authorityUpdate(authority); return new ResponseDTO(1, ""); } 간단히 이런 코드가 있습니다. authorityUpdate는 authority 받아서 this.authority = authority; 해주는 부분입니다. 이 경우 당연히 변경 감지가 돼서 update가 돼야 한다고 생각하는데요 되지 않습니다 지금 이 애플리케이션의 특이점이라고 한다면 DB가 두 대가 붙어 있습니다 그래서 쿼리dsl 사용할 때도 DB를 지정해서 EntityManager를 불러와야 했습니다 저것도 그래서 안되나 싶은데 제가 확인 해봐야 할 것이 뭐가 있을까요?? 메인 DB 연결된 쪽은 잘 됩니다 findBy~ 후에 영속성 컨텍스트가 바로 끊기는거 같습니다. 그렇게 생각한 이유는 getById로 해봤는데 could not initialize proxy ~ no session 이런 에러가 발생하고 findById 하면 에러는 나지 않는데 업데이트가 안됩니다. osiv true로 하고도 해봤습니다. 그냥 save 하면 update 되긴 하는데 그건 선생님께서 알려주신 방법이 아니기도 하고 대체 왜! 안되는지 궁금합니다 ㅠㅠ

Querydsl4RepositorySupport에 @Repository와 @Autowired

미해결

실전! Querydsl

안녕하세요. 강의 잘 보고 있습니다. 궁금한 점이 있습니다. Querydsl4RepositorySupport는 abstract class인데 왜 @Repository를 붙이는건가요? 실체 구체화할 부모 클래스에 @Repository를 붙이면 되는것 아닌가요? Querydsl4RepositorySupport는 abstract class라 객체로 생성이 안되는데 빈으로 등록이 가능한가요? 이어서 setEntityManager에 @Autowired를 붙임으로써 의존성을 주입하고 있습니다. 그때에 entityManager라는 빈을 등록해주겠죠. 그런데 setEntityManager는 언제, 누가 호출하게 되는건가요?

Job 실행지연 시 같은 Job실행 방지

미해결

스프링 배치

(현재 환경은 job 스케줄링을 jenkinse로 하고 있고, 서버를 1개만 사용할 계획입니다.) 스케줄링대로 5분 간격으로 여러 Job을 실행시키는 경우 1번 Job이 실행이 지연으로 1번 Job 이 배치를 돌고 있는 중에 다시 1번 Job실행 순서가 오는 경우, 즉, 같은 Job이 실행 중인 경우에는 같은 Job실행을 방지하고 싶은데 Listener를 이용하는 방법 말고 혹시 다른 방법으로 이를 구현할 수 있는 방법은 없을까요?? JobOperator.stop으로 막아야 할 거 같은데 어떤 구현객체, interface를 활용해야 할지 모르겠습니다.

강사님께서 그 전 강의에서, RetrieveAPIView에 serializer_class를 쓰는 대신, 직접 dict로 매핑시켜 구현하는 코딩 방식으로 구현해주셔서 ViewSet으로 migration하는 과정에서 serializer_class를 PostListSerializer하나만 쓰면, 다 동작이 하게끔 구현을 해주셨는데요. 만약, RetrieveAPIView의 리팩토링 없이, 하나의 ViewSet으로 구현한다고 하면, 어떻게 구현을 하면 될까요? serializer_classes라는게 존재할까 싶어 DRF 공식문서를 찾아봤지만 어쨌든 CBV에선 하나의 serializer_class만 지정이 가능하더라구요. 강사님의 방법을 알고싶습니다.
