원하는 키워드의 값을 담은 상수를 console.log(key,value) 하면 줄바꿈되면서 안에 있는 전체 값들이 나오더라구요  ( const key = $(el).attr("property").split(":")[1]; const value = $(el).attr("content"); 부분입니다)근데 이 값들을 db에 저장하려 for문을 이용해 배열에 넣어봤더니 console.log(key,value)해서 나온 값들이 아닌 마지막 값만 들어갑니다 key와 value에 어떤 형태로 값이 스크랩핑되어 들어가있는건가요..?상수에 배열형태로 들어간 것도 아니고 한줄로 값이 들어간 것도 아니고 .. console.log하면 전체가 나오기는 하나줄바꿈이 되어 나와서 갈피를 못잡겠습니다..스크래핑한 값을 어떻게 저장을하고 넘겨야할지 db로 넘겨야할지 전혀 모르겠습니다................................. 이틀동안 찾아봐도 해결이 안되어서 질문 남깁니다..

윈터로드님 알려주신 덕분에 완강할수잇었습니다ㅠㅠ 인프런 강의 첫 수강완료증을 받앗네요제 프로젝트에 큰오류를 발견했습니다,,,, 새일기쓰면 똑같은게 2개가 만들어지는데 이거 어디서 오류를 수정해야 하는지알수잇을까요?

안녕하세요 선생님게시글 수정을 route에서 처리하고 마지막으로 res.status(201).json(fullPost) 이렇게 게시글 정보를 담아서 보내려는데 자꾸 사가에서 데이터를 undefined로 받습니다..담기 전에 fullPost를 콘솔로 찍어보면 데이터가 잘 들어가 있는데 프론트로 넘어가면 undefined로 바뀌어요.그래서 단순 문자열도 res.status(201).json('성공');이런 식으로 보내봤는데도data가이렇게 undefined로 뜨는건 어느 부분을 봐야 하는 건가요? 

처음에 .env파일을 깃허브에 올리시길래 띠용했지만 곧바로 수정하시는군요.지금은 연습 중이라서 올라가도 크게 문제가 없을 것 같고, 또한, 강사님께서 .env가 깃허브에 올라갔을 때 어떻게 대처하는지 알려주시기 때문에 연습 용도로도 좋아보입니다..env파일을 올리는게 찜찜하신 분들은 인스턴스 환경변수 분리까지 보신 뒤에 하시는게 좋을 것 같고, 나는 .env가 노출 된 상황을 한 번 연습해보고 싶다. 하시는 분들은 차례대로 진행하는 것도 좋을 것 같습니다!

안녕하세요 자꾸 글 작성했다 지웠다 해서 죄송합니다.직접 검색해보고 해결해보려했는데 안되어서 다시 남깁니다. 7.6장 model/index.js 파일중에서const config = require('../config/config')[env];수업에 나왔던 이 코드와 동일하게 동작하게끔 es모듈 방식으로 import하는 코드를 작성하려 합니다import cfg from '../config/config.json' assert { type : 'json' } const config = cfg[env]; 이렇게 작성해 보았는데(node:10404) ExperimentalWarning: Importing JSON modules is an experimental feature and might change at any time(Use node --trace-warnings ... to show where the warning was created)이런 경고가 뜨고, 무시하고 app.js를 실행하면 서버가 실행되긴 하는데 책&예제코드에 나오는 메시지와는 다른 아래와 같은 메시지가 나옵니다.Executing (default): SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_NAME = 'users' AND TABLE_SCHEMA = 'nodejs'Executing (default): SHOW INDEX FROM users FROM nodejsExecuting (default): SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_NAME = 'comments' AND TABLE_SCHEMA = 'nodejs'Executing (default): SHOW INDEX FROM comments FROM nodejs 어떻게 해야 es모듈에서도 동일하게 동작하게끔 할 수 있는지 궁금합니다. 

cmd창에서 flyctl deploy를 실행하면 아래와 같은 에러가 뜹니다.도커 빌더 이미지 관련 오류인것 같은데 어떻게 해결해야 하나요?urce: failed to fetch builder image 'index.docker.io/heroku/buildpacks:20': resolve auth for ref index.docker.io/heroku/buildpacks:20: error getting credentials - err: exec: "docker-credential-desktop": executable file not found in %PATH%, out: ``

안녕하세요 선생님.시퀄라이즈에서 모델 끼리 관계성을 맺어서 route에서 const post = await Post.create({'이하 생략'}); 이런 식으로 하면 Post가 Hashtag와 관계성이 있을 때 post.addHashtags를 할 수 있다는건 알겠는데..이건 create시에만 쓸 수 있는 건가요?이런 질문을 드리는 이유는 게시글에서 해시태그를 수정하려 하니까 일단 Post.update를 해야 하는데, 그러면 따로 Hashtag테이블에 있는 해시태그를 수정하려니까 중간 테이블이 있어서 쉽지 않을것 같아 그냥 row query로 Hashtag중간테이블에서 게시글 아이디를 지워버리고 다시 해시태그를 생성하려고 post.addHashtags를 사용하고 싶어서 그렇습니다. 

로그인 회원가입시 이런 오류코드가 뜨는데, DB와 백엔드 연결에서 문제가 나는 건가요?

한줄로 if문을 쓰실 때 return을 붙이시는 이유가 있나요??제가 감히 생각해보면 return을 붙일 필요가 없는 것 같은데코드를 좀 더 명확하게 하시려고 붙이시는 건가요??

제가 백엔드 공부도 처음이고 언어 공부에서도 c 이후로 는 거의 하지 않았습니다. 프로젝트 단계로 넘어가기 전 언어 공부를 해야 더 도움이 될거같은데 typescript 나 자바스크립트를 선행 언어 공부를 한 후에 들어야 도움이 더 잘 될까요? 아니면 공부 없이도 듣기 괜찮을 까요?

 안녕하세요 자유게시판을 어느정도 구현해서 netlify를 통해 배포해보려고 하니 cors 문제로 api가 작동하지 않습니다. 어떻게 해야 해결할 수 있을까요 ? Access to fetch at 'https://backendonline.codebootcamp.co.kr/graphql' from origin 'https://brilliant-rabanadas-0c6769.netlify.app' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header has a value 'http://localhost:3000' that is not equal to the supplied origin. Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

routes/post.js 게시글 등록 요청시User객체에 id값을 req.user.id로 설정하려하는데에러나서 req.user 콘솔 찍어보면 undefined 가 출력됩니다.passport/index.js 에서 deserializeUser 를 통해 user값이 req.user로 세팅되는걸로 들었는데 반환값이 없네요 ..passport.deserializeUser()에 console.log 찍어보면 아무것도 출력되는게 없습니다.
