안녕하세요 남박사님..   ubuntu 에서 docker설치 까지 진행한후 ... 강좌중   프로젝트를 docker 이미지로 만들어서 배포 내용중 10:11초까지 진행했는데요   강의 듣고있다가 컴퓨터 문제상 잠시 멈추고.. 재부팅을 하니까 portainer 웹사이트가 열리지 않은데.. 연결 시킬려고 하면 어떻게 해야할까요?   해당 아이피에 9000을넣고 실행해도 연결이 안됩니다. ..           docker의 볼륨을 만들어서 portainer를 실행시킬려고 해도.. 이미 있다고 나오는데.. 검색을 해도 잘안나오는거 같아서 여쭤봅니다..!

안녕하세요 남박사님   이번에 진도를 진행하다가... 우분투에서 몽고db연결하는 부분을 따라하다가 진행이 안되서 다시 질문 올립니다!   구글링 해봐도 몽고db사이트가서 봐도... 이해가 잘 안가더라구요.. 터미널에서 20:44초 처럼 코드를 작성하니까.. key값을 가지고 올수 없다고 하는데.. 기존방법에서 다른 방법으로 바뀌었을까요..?   버추얼 머신때문은 아니겠죠..? ms꺼는 설치가 아예안되서 버추얼박스로 잠깐 사용하다가 렉도심하고 잘안되서요.. 현재 내용에서 진도가 안나가서 지금은 VMware 설치해서 사용중입니다..!      

안녕하세요 남박사님   남박사님 덕분에 강의를 잘듣고 진도를 나가고 있습니다. 이해가 안가는 부분도 아직 있지만 열심히 배울려고 노력하고 있는데요! 이번 댓글기능 만들기 부분에서 오류나는 부분있어서 질문올립니다.   댓글기능 구연하고 마지막 부분에서 jinja2.exceptions.UndefinedError: 'pymongo.cursor.Cursor object' has no attribute 'count'라고 오류가 나는데.. 저번에 {% if comments.count() > 0 %} 이부분이 몽고db 부분하고 연동이 안되는거 같아서 버전 차이라고 하셔서 count_documents({조건})로 변경해봤는데.. 오류는 나더라구요..!   - 오류 -     -코드 - -board.py-   from

남박사님 안녕하세요   이번 보안강화 - 로그인정보 암호화 강좌 진행중에.. 오류를 해결하지 못해서 질문 드립니다.   우선 내용은 이렇습니다.   1. werkzeug.security 설정진행중 패스워드 보안작업중에 "pass": hash_password(pass1) 로 변경후에 회원가입을 하면 비밀번호가 일치하지 않습니다라고 계속 나오더라구요.. 몽고db에서 내용지워도 마찬가지 입니다. 그전에는 정상적으로 로그인이 되었습니다.   2. flask_wtf.csrf import CSRFProtect 를 적용하는데 pip install flask-wtf를 설치해도 오류가 나오더라구요..       문제 사진   1번         2번       3번            4번           5번               코드     -

안녕하세요 남박사님!   저번에 질문 올렸는데요!.... 플라스크 프로젝트를 모듈화 하여 패키징 하기 부분에서 오류나서 질문을 드렸었습니다! 죄송합니다만 .... 댓글 달아주셨는데.. 제가 궁금한 부분도 다시 댓글 달았습니다. 답변 부탁드리겠습니다.   지금 진도는 javascript, iQuery 폼 검증 기능 추가하기 입니다.   모듈화 부분에서 전부 모듈화 하고... venv 들어가 있는 상태에서 재생버튼 눌러서 강제로 실행하니까.. 코드 오류 무시하고 실행이 되더라구요...! 왜그런지는 모르겠습니다!   실행이되서 진도를 나갔는데 다른 부분은 전부 정상적으로 적용되는데.. 한곳에서 적용이 안되는 구간이 있어서 질문 올립니다!   -코드 오류 -1 -   -코드 오류-2 -   -글목록 수정- 글목록

안녕하세요 남박사님..!   계속 질문 해서 죄송합니다..ㅠ   이번은 모듈화 과정에서 계속 문제가 나서 어떻게 해야할까 해서 질문을 올립니다..! 코드가 아예 먹통이 되는거 같더라구요..!   직접 임포트해서 넣은 common,py / filter.py 는 pylint 내용은 나오더라도 오류는 안나는데.. 다른거는 직접 넣어도 전부 오류가 나오네요..!   다른분들이 올리신 글보고 vscode settings에서 format on save 체크가 되어 있어서 해제 했습니다!   이 부분도 이렇게 추가해서 해봤는데 같았습니다!   from main import member from main import board from main.filter import format_datetime from main.common import login_required     board.py 코드 부분에서 edit 에 is data in None: <<< None이 빨간줄로 표시가 나오던데 왜그런걸까요?   @app.route("/edit/<idx>", methods=["GET", "POST"]) def board_edit(idx):     if request.method == "GET":         board = mongo.db.board         data = board.find_one({"_id": ObjectId(idx)})         if data in None:             flash("해당 게시물이 존재하지 않습니다.")             return redirect(url_for("lists"))         else:             if session.get("id") == data.get("writer_id"):                 return render_template("edit.html", data=data)             else:                 flash("글 수정 권한이 없습니다.")                 return redirect(url_for("lists"))     else:         title = request.form.get("title")         contains = request.form.get("contents")         board = mongo.db.board         data = board.find_one({"_id": ObjectId(idx)})         if session.get("id") == data.get("writer_id"):             board.update_one({"_id": ObjectId(idx)}, {                 "$set": {                     "title": title,                     "contents": contains,                 }             })             flash("수정 되었습니다.")             return redirect(url_for("board_view", idx=idx))         else:             flash("글 수정 권한이 없습니다.")             return redirect(url_for("lists")     -

안녕하세요   남박사님 도움을 많이 주셔서 강좌 잘 진행하고 있습니다! 몇일동안 헤매던것을 해결되서 정말 좋습니다!   궁금한 사항이 있어서 질문 올립니다.   join창에서 회원가입을 하면 몽고db에 데이터가 정상적으로 넣어지는걸 확인할수있고 리스트란에서 게시물 작성 및 삭제등이 원활하게 이루어 지고 있습니다. 궁금한부분은 회원가입후 리스트나 로그인창으로 안넘어 가는거 같아서 질문을 올립니다! 회원로그인창으로 링크주소를 바꾸면 오류가 나는거 같더라구요.. 어떻게 해야할지 몰라서 질문 다시 올립니다!   -회원가입-   -회원 가입후-   - 로그인 -   -게시판 목록-     -게시글 자성란-   -게시글 작성후 -   -회원가입 데이터-         - run.py -   from flask
