The above exception was the direct cause of the following exception:

이런식으로 오류가 뜨는데 model.py 문제인가 싶어서 확인 해봤더니 그건 아니었어요.
models.py에서 Question을 저장한 이름도 써봤는데 저렇게 뜹니다ㅠㅠ
혹시 모르니 models.py 소스코드도 올립니다ㅠㅠ
몇 시간 동안 계속 고쳐봤는데 안됩니다ㅠㅠ
지금 서버 구동까지 다 한 상태에요..!

from django.db import models
from django.contrib.auth.models import User

class Question(models.Model):
    subject = models.CharField(max_length=200)
    content = models.TextField()
    create_date = models.DateTimeField()
    modify_date = models.DateTimeField(null=True, blank=True)
    voter = models.ManyToManyField(User, related_name='voter_question')
    author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='author_question')


    def __str__(self):
        return self.subject

class Answer(models.Model):
    author = models.ForeignKey(User, on_delete=models.CASCADE,
                               related_name='author_answer')
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    content = models.TextField()
    create_date = models.DateTimeField()
    modify_date = models.DateTimeField(null=True, blank=True)
    voter = models.ManyToManyField(User, related_name='voter_answer')

    author = models.ForeignKey(User, on_delete=models.CASCADE)

class Comment(models.Model):
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    content = models.TextField()
    create_date = models.DateTimeField()
    modify_date = models.DateTimeField(null=True, blank=True)
    question = models.ForeignKey(Question, null=True, blank=True,

Question 데이터를 저장하기 위해서는 author 에도 값을 채우셔야 합니다. - 박응용님, 2022년 6월 19일 10:29 오전 추천 , 대댓글
@박응용님 author 값을 어떻게 채우라는 말씀이실까요? - cvbdsadk259님, 2022년 6월 20일 2:03 오후 추천 , 대댓글
@cvbdsadk259님 author = User.objects.get(username='...') 으로 조회한후에 대입하시면 됩니다. - 박응용님, 2022년 6월 20일 5:18 오후 추천 , 대댓글
