파이썬/장고 웹서비스 개발 완벽 가이드 with 리액트
안녕하세요, 선생님! 오늘도 신기한 기능 알려주셔서 감사합니다. 그런데 model.py와 view.py 수정 후 migrate까지 했는데도, FieldError가 발생합니다. create_at에 문제가 있다고 추측만가능하고, 해결방법을 찾지 못했습니다. 정확하게 이 에러가 어떤 상황에서 발생하는지, 어떻게 해결할 수 있는지 조언해주실 수 있으신가요? 에러화면 view.py from datetime import timedelta from django.contrib import messages from django.contrib.auth import get_user_model from django.contrib.auth.decorators import login_required from django.db.models import Q from django.shortcuts import render, redirect, get_object_or_404 from django.utils import timezone from .forms import PostForm from .models import Post @login_required def index ( request ): timesince = timezone. now () - timedelta ( days = 3 ) post_list = Post.objects. all ()\ . filter ( Q ( author = request .user) | Q ( author__in = request .user.following_set. all ()) )\ . filter ( created_at__gte =timesince ) suggested_user_list = get_user_model ().objects. all ()\ . exclude ( pk = request .user.pk)\ . exclude ( pk__in = request .user.following_set. all ())[: 3 ] return render ( request , "instagram/index.html" , { "post_list" : post_list, "suggested_user_list" : suggested_user_list, }) models.py import re from django.conf import settings from django.db import models from django.urls import reverse # Create your models here. class BaseModel (models.Model): created_at = models.
