안녕하세요.  Contest Leaderboard 를 풀다가 궁금한 점이 있어서 질문드립니다.    선미님은 FROM 절 서브쿼리로 문제를 푸셨는데,  저는 SELECT절 서브쿼리로 풀고 있었습니다.    토대가 되는 쿼리는 비슷한 것 같은데  오류가 나네욥 ㅠㅠ    아래 쿼리 한번만 확인해주시면 감사합니다. 더불어 본문제에서는 SELECT절 서브쿼리가 FROM절 서브쿼리보다 별로인가요?    SELECT h.hacker_id     , h.name     , (SELECT SUM(max_score) AS mx        FROM (                SELECT hacker_id                     , challenge_id                     , MAX(score) AS max_score                FROM submissions                GROUP BY hacker_id, challenge_id                 ) sub        WHERE s.hacker_id = sub.hacker_id        GROUP BY hacker_id         HAVING mx != 0       ) total_scoreFROM submissions s INNER JOIN hackers h ON h.hacker_id = s.hacker_idGROUP BY h.hacker_id, h.nameORDER BY total_score DESC, h.hacker_id

npm start하고 메트로서버 키고  안드로이드는 빌드잘되는데  ios는 앱이 켜져서 핸드폰에 아이콘은 보이긴하는데 error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65.

선생님 안녕하세요 좋은 강의 감사합니다.   cifar100 이미지를 사용해서 모델을 돌려보고 싶은데, 매번 다운받으려니 시간이 너무 오래걸리더라고요 혹시 cifar100 이미지를 다운받아놓고 불러다 쓸 수 있는 코드가 있을까요? 인터넷을 찾아보니 pickle 이런것을 사용해서 풀기는 하는데, batch 마다 풀거나, 아니면 코드가 너무 복잡해서   (train_images, train_labels), (test_images, test_labels) = cifar10.load_data() 이렇게 딱 한줄로 푸는 방법을 알려주시면 정말 감사하겠습니다!

읽어보니 16.8.5에 의존한다고 나오는거 같은데 설치과정에서부터 막혔는데 혹시 해결방법이 있을까요..  

안녕하세요 선생님. 현재 제가 업무에서 전자정부프레임워크를 활용하고 있는 신입개발자입니다.  현재 저희 프로젝트는 외부업체가 제공하는 지니웍스CMS를 활용해서 관리자페이지도 구현하고, 웹사이트를 구성했는데요. 사용자가 로그인오류가 났을때, 관리자페이지에서 비밀번호를 임시발급하는 버튼이있더라구요.  하지만 뭔가 CMS가 제공하는 기능만 이용하기에는 찝찝해서 그 원리를 알고싶은데요...   뭐가 궁금하냐면,  예를들어 사용자가 회원가입하면 DB에 해시로 비밀번호가 저장이되는데, 이때, 위에서 언급했듯이, 사용자가 로그인오류땜에 접속이안되고, 개발자 역시, DB에 해시번호로 비밀번호가 저장되어있으니, 어떻게 임시로 비밀번호 컬럼을 UPDATE로 수정 못하잖아요. 해시로 저장하는것이 개발자도 사용자의 계정으로 로그인 못하도록 법적으로 되어 있다고 알고있는데...   이러한 상황을 종합적으로 봤을떄, 임시 비밀번호를 어떤식으로 발급을 해줘야하는거죠??  (임시 비밀번호를 생성하는 로직은 알고있슴다.)     그냥 단지 CMS가 제공하는 '임시비밀번호 발급'버튼으로 임시 비밀번호를 발급하는것이 정신에 좋은걸까요. 신입이라 CMS를 첨봐서, 질문드려요. 괜히 제가 복잡하게 알 필요도없는걸 알려고 하는건지 궁금합니다!     

Configuration 서버의 정보가 변경이 됐을 때 정보를 다시 가지고 오는 방법들이 있는데 두번째 방법인 actuator를 이용하는데 refresh, health, beans 전부 안됩니다.   health_check로 값을 확인하면 아래처럼 잘뜹니다. It's Working in User Service, port(local.server.port)=56550, port(server.port)=0, token secret=user_token, token expiration time=86400000     참고로 user-service에 bootstrap.yml 파일은 spring: cloud: config: uri: http://127.0.0.1:8888 name: ecommerce # ecommerce.yml 파일을 가져온다.   git-local-repo에 있는 ecommerce.yml은 다음과 같습니다. token: expiration_time: 86400000 secret: user_tokengateway: ip: 192.168.45.163   그리고 config-service에 있는 application.yml 파일은 server: port: 8888spring: application: name: config-service cloud: config: server: git: uri: file://C:\Users\test\IdeaProjects\Inflearn\msa\git-local-repo 다음과 같습니다. 그런데 actuator 방법은 /health와 /beans 모두 Whitelabel Error Page가 뜨고   /refresh로 post 요청하면 {     "timestamp": "2022-08-20T11:28:26.532+00:00",     "status": 404,     "error": "Not Found",     "message": "No message available",     "path": "/actuator/refresh" } 위와 같은 에러가 발생합니다.. 참고로 user-service의 application.yml에 management: endpoints: web: exposure: include: refresh, health, beans 을 추가했습니다. 그런데 강의처럼 자동완성은 전혀 뜨지 않았습니다. endpoints 부터 자동완성이 없었습니다. 대체 왜이런걸까요?     그리고  user-service에서 실행시키면 도대체 왜 config-service 프로젝트에 있는 application.yml 파일에 등록된 `uri: file://C:\Users\test\IdeaProjects\Inflearn\msa\git-local-repo` ( 제 ecommerce.yml 주소) 이 주소를 읽는건지 모르겠습니다. user-service의 bootstrap.yml에는 ecommerce(.yml) 밖에 없는데… 저 config-service에 있는 application.yml을 참조 하라는 표시를 대체 어디에 한건가요??

vsc에서 함수에 커서를 두고 F12를 누르면 그 함수가 정의된 곳으로 이동을 하는데요 자바스크립트 함수를 찾고 싶은데 js파일 간에 찾는건 되는데 .php파일에 선언 된 함수는 찾지를 못하네 예를 들어 function.php파일에서 aaa라는 함수를 선언하고test.php파일에서 aaa함수를 호출한다고 했을 때 test.php파일의 aaa함수에 커서를 두고 F12를 누르면 function.php파일로 가야 정상인데 작동을 하지 않네요ㅠㅠ 해결 방법이 없을까요?

안녕하세요 강의 잘 듣고 있습니다.!   저번에 sequelize-auto 답변 듣고 잘 이용하고 있습니다!ㅎㅎ 여기서 하나 더 질문이 있는데요 외부 테이블을 sequelize-auto로 받아와서 서버를 돌리는데  Error: Invalid Instance definition. Only one autoincrement field allowed. 이러한 애러가 떴습니다. 테이블에 autoincrement가 하나씩만 있어야하는 애러같은데요 sequelize orm에서는 테이블 당 autoincrement설정이 하나씩만 있어야하나요? 이게 아니라면,, 2개의 autoincremnet를 쓰려면 어떤 설정을 해줘야하나요 답변 부탁드려요,,ㅜㅜ

1. 엔티티에서 setter는 지양하라고 말씀하셨는데 예를 들면 Order의 연관관계 메서드를 작성 시 OrderItem의 setter가 사용됩니다. 이 때 setter를 사용하지 않고 양방향 연관관계 세팅을 할 수 있는 방법이 무엇이 있을까요?   2. 양방향값 세팅은 양방향연관관계일 때 필수적인 건가요?

    강의 내용에서는 테스트 완료 후 첫번 째 사진처럼 각각의 함수명이 뜨는데 , 저는 3개의 테스트 완료 라고만 뜨고 하나씩은 안뜨는 이유를 잘 모르겠습니다!   옆쪽의 확장 화살표를 눌러봐도 밑의 3가지 테스트가 뜨지 않습니다.

Login에노테이션의 로직부분의 코드에 의문이 있습니다. 도데체 어떻게 저게 Login에노테이션의 로직부분이라는 것을 알 수 있어서  로그인 에노테이션이 실행될 때 저 로직이 실행이 되는 지 궁금합니다.   parameter.hasParameterAnnotation(Login.class);<-- 이부분때문에 Login관련 에노테이션인건지잘 모르겠습니다.

User와 Post는 User엔티티가 one에 해당하고 Post엔티티가 many에 해당되어 User.ts에서 OneToMany(()=>postMessage)...이런식으로 작성하고 Post.ts에도 ManyToOne(()=>User)...와 같이 작성하는 것을 확인했습니다.  그러면 User와 Sub도 onetomany관계인데 왜 Sub엔티티에서만 ManyToOne(()=>User)...로 작성하고 User에는 Sub에 대해서 OneToMany데코레이터를 사용하지 않는 것인지 질문드립니다.
