웹사이트 회원가입후 게시판으로 넘어가는 부분 질문 (join 부분)

Question

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- -

역시나 프로그램의 흐름을 생각해보시면 됩니다.   "궁금한부분은 회원가입후 리스트나 로그인창으로 안넘어 가는거 같아서 .."   라고 생각하셨으면 회원 가입 후 프로그램이 어떤처리를 하고 있는지 살펴보면,   @app.route("/join", methods=["GET", "POST"]) def member_join(): ... 생략 ... members.insert_one(post) return ""   그냥 이렇게 return "" 하고 있으니 아무것도 안하게 됩니다.   @app.route("/join", methods=["GET", "POST"]) def member_join(): ... 생략 ... members.insert_one(post) return redirect(url_for("member_login"))   위처럼 수정하면 회원가입 후 로그인 페이지로 이동하게 됩니다.   웹프로그램은 흐름을 잊지 마세요.
