Question

안녕하세요 웹개발 입문부분 강좌를 거의다 들었는데.. 오류가 나는 부분이 있어서.. 질문을 올립니다! 문제는..join 로그인 하면 몽고db에서 이메일 주소가 null로 표시가 되서.. 동작이 되지 않는점이 있습니다.. 비슷한 증상을 찾기 어려워서 질문 남깁니다! -화면- -join- -mongoDB- -list- -list 로그인 페이지- next_url << 이게 문제가 나왔었는데 다른 코드들 참고 했는데 해결은 됬습니다. -run.py- from flask import Flask from flask import request from flask import render_template from flask_pymongo import PyMongo from bson . objectid import ObjectId from flask import abort from flask import redirect from flask import url_for from flask import flash from flask import session from functools import wraps import math import time from datetime import datetime , timedelta app = Flask ( __name__ ) app.config [ " MONGO_URI " ] = " mongodb://localhost:27017/myweb " app.config [ " SECRET_KEY " ] = " abcd " app.config [ " PERMANENT_SESSION_LIFETIME " ] = timedelta ( minutes = 30 ) mongo = PyMongo ( app ) def login_required ( f ): @ wraps ( f ) def decorated_function ( *args , **kwargs ): if session . get ( " id " ) is None or session . get ( " id " ) == "" : return redirect ( url_for ( " member_login " , next_url = request . url )) return f (* args , ** kwargs ) return decorated_function @ app . template_filter ( ' formatdatetime ' ) def format_datetime ( value ): if value is None : return "" now_timestamp = time . time () offset = datetime . fromtimestamp ( now_timestamp ) -

그런문제는 프로그램의 흐름을 한번 먼저 생각해보시면 어디에서 문제가 생길지를 미리 예측해볼 수 있습니다. 회원가입을 했는데 이메일값에 문제가 있다면 회원 가입 폼, 회원가입 처리 함수, 이런식으로 프로그램의 흐름을 생각해보며 하나씩 원인을 분석해보는 습관을 들이시는게 좋습니다. 물론 첨부터 쉽지는 않습니다. 어쨌든 그런 순서로 올려주신 코드를 보니, 위와 같이 작성되어있는걸 봤습니다. nmae 이 아니라 name 입니다. 수정해서 한번 다시 해보시기 바랍니다.
