지금 노션 페이지에 올라와 있는 JSON데이터의 경우 키값에 ""가 안붙어 있어서 loaddata시 오류가 나는데 어떻게 해야하나요 ㅠㅠ

안녕하세요. 강의영상 소스코드와 PDF 소스가 꼭 맞아야되는지는 모르겠으나...실습하면서 잠깐 헤매서 내용 공유드립니다. 영상에서 @Query 등록시  @Query("select new study.datajpa.dto.MemberDto PDF 내용 @Query("select new study.datajpa.repository.MemberDto

개발자 모드로 보면 저렇게 에러가 난다고 계속 뜹니다 ㅠㅠ start.js 코드는 판다님께서 해주신 것과 동일하게 짰는데 왜 이러는지 모르겠네요ㅠㅠ data.js에서 바뀐 부분이 있는데, 질문은 12개 그대로이고 유형이 12간지 총 12개에서 16개로 바뀌었습니다! 그리고 answer선택지도 a b c 세 개에서 a b 2개로 바뀌었습니다. start.js 코드는 다음과 같습니다!! (그리고 좋은 강의 제공해주셔서 너무 감사합니다..!! ㅠㅠ)

models.py 파일 작성후 터미널 창에서 python magage.py migrate 코드 실행시 TypeError : argument of type 'PosixPath' is not iterable 이라는 에러가 뜨는데 어떻게 해결해야 할지 모르곘습니다ㅠ

테스트 시 @Transactional 은 기본적으로 rollback 으로 작동한다고 하셨는데 일반적으로 db에서의 rollback 은 db에 쿼리가 나간 이후에 그 결과를 다시 원복하는 것으로 알 고 있습니다. 그런데 이 경우에는 아예 db로 insert 쿼리 자체가 나가지 않은 것으로 보이는데 그러면 최초 영속성 컨텍스트에만 저장하고, 종료 시점에는 db에 쿼리가 나가지 않고 끝나는게 맞나요?

웹디자인기능사 실기 공개문제를 읽어보다가 궁금한 점이 생겨서 질문드립니다 폴더에 제공된 로고를 포토샵을 통해 컬러를 변경해서 넣어야 하는건 이해가 되는데요, 가로세로 비율을 유지해야한다는 내용이 이해가 잘 안가서요..! 200x40 크기로 만들면 안되는건가요..?

안녕하세요 선생님, 수업 감사히 잘 듣고 있습니다. 한가지 여쭤보고 싶은게 있습니다 선생님께서 실습하신 것처럼 결과가 잘 나오는데, 두 번 정도까지는 괜찮다가 포스트맨으로 요청을 다시 보내면 아래처럼 오류가 뜹니다. 이런 오류 이후에는 다시 한 두번 정도는 정상적으로 동작하다가 동일한 오류가 납니다. apigateway-service를 확인하니 다음과 같은 에러 내용을 확인하였습니다. io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: localhost/127.0.0.1:56873 Suppressed: reactor.core.publisher.FluxOnAssembly$OnAssemblyException:Error has been observed at the following site(s): |_ checkpoint ⇢ org.springframework.cloud.gateway.filter.WeightCalculatorWebFilter [DefaultWebFilterChain] |_ checkpoint ⇢ HTTP GET "/first-service/check" [ExceptionHandlingWebHandler]Stack trace:Caused by: java.net.ConnectException: Connection refused: no further information at java.base/sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) ~[na:na] at java.base/sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:779) ~[na:na] at io.netty.channel.socket.nio.NioSocketChannel.doFinishConnect(NioSocketChannel.java:330) ~[netty-transport-4.1.60.Final.jar:4.1.60.Final] at io.netty.channel.nio.AbstractNioChannel$AbstractNioUnsafe.finishConnect(AbstractNioChannel.java:334) ~[netty-transport-4.1.60.Final.jar:4.1.60.Final] at io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:707) ~[netty-transport-4.1.60.Final.jar:4.1.60.Final] at io.netty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:655) ~[netty-transport-4.1.60.Final.jar:4.1.60.Final] at io.netty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:581) ~[netty-transport-4.1.60.Final.jar:4.1.60.Final] at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:493) ~[netty-transport-4.1.60.Final.jar:4.1.60.Final] at io.netty.util.concurrent.SingleThreadEventExecutor$4.run(SingleThreadEventExecutor.java:989) ~[netty-common-4.1.60.Final.jar:4.1.60.Final] at io.netty.util.internal.ThreadExecutorMap$2.run(ThreadExecutorMap.java:74) ~[netty-common-4.1.60.Final.jar:4.1.60.Final] at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) ~[netty-common-4.1.60.Final.jar:4.1.60.Final] at java.base/java.lang.Thread.run(Thread.java:834) ~[na:na] 너무 잦은 요청으로 인한 오류일까요? 그러기엔 적당한 텀을 두고도 요청을 했는데 이 정도 요청을 정상 처리 못해준다는게 의문스럽습니다.

안녕하세요. 하나의 예를들면 Springboot에서 구현한 웹애플리케이션을 jar로 말고 그 웹애플리케이션에 대한  환경설정과 같은 것과 같이 DockerFile로 만들고 이 DockerImage를 제킨스 CI에 전달하면 제킨스가 배포를 해준다. 또는 Springboot에서 구현한 웹애플리케이션을 Jar로 말고 여기에 대한 설정 DockerFile를 DockerImage로 만들어서  Docker Repositroy에 있는 환경에 대한 Image를 pull로 갖고와서 두개의  Image를 하나의 Image로 만들고 젠킨스 CI에 보내면.. 이제 이걸 run시켜서 컨테이너로 만든다. 이렇게 이해해도 괜찮을까요. 질문이 너무 애매모호하죠? ㅠ______ㅠ  Springboot에서 만든 WebApplication을 Docekr File로 Image를 만들고 그 컨테이너를 만드는 과정이 너무나도 헷갈립니다. 

과제 3번 하는 중에 어디에 INSERT 를 추가해야하는지 찾아봤는데 없더라구요 ㅠ select 는 있는데 insert는 없어도 insert가 되나여?

안녕하세요 선생님, 선생님 강의 수강 중인 예비개발자 Andy Bae입니다. 실행결과  번호가 의도한 것과 다르게 나와 질문드립니다. 어디를  확인해보면 될까요?

혹시 시험장에 인터넷이 안되는걸로 알고있는데 체크가 가능할까요??

혹시 설문 응답자가 입력한 값이랑 결과값을 엑셀로 정리하거나 하려면 어떻게 해야되나요??

안녕하세요 제로초님. select문안에 별칭을 줄려고 합니다. const data = await this.createQueryBuilder('results') .orderBy('results.problem_id') .select(['results.problem_id AS id', 'results.answer', 'results.result']) .getMany(); return data; 저렇게 하니 빈배열으로 나오는데 어떻게 하면 좋을까요? 별칭없을때(AS 없으면) 정상동작합니다. 감사합니다.

여러줄 한번에 # 넣는 단축키 어떻게 하신건가요..?ㅎㅎ 감사합니다. 

안녕하세요 그 전의 DFS 강의를 보거나 하면 12시 3시 6시 9시 방향으로 검색하면서 갔는데 이번 문제에서는 왜 꼭 왼쪽 먼저 비교하고 오른쪽 비교하고 위쪽을 비교하나요? 

이건 좀 너무하네요. 강의에 대한 업데이트도 없고 q&a 도 답변도 주시지도 않고 이걸 55,000원을 주고 구입한게 너무 아깝네요. 듣다보니 안되는게 많아 환불하려고 했더니 환불도 안되고... 관리 좀 부탁합니다.

신입개발자 뽑으실때는 탑클래스의 알고리즘을 풀어야한다고 하셨는데, 경력직으로 지원한다면 코딩테스트의 난이도가 신입보다는 좀 낮은 수준인가요?

Tableau 2021.1 버전 사용하고 있는데 동영상에 나오는 것처럼 측정값의 레코드 수가 없습니다. 대신 측정값을 더블 클릭하면 아래와 같이 나오는데 이중에서 합계(Quantity)를 사용하면 비슷한 결과가 나오긴 합니다.. 무엇을 사용해야 하나요??
