    if modeladmin.model._meta.app_config in app_configs:
AttributeError: 'Comment' object has no attribute 'model'

вот мой код в моделях:

import datetime

from django.db import models
from django.utils import timezone

class News(models.Model):
    news_title = models.CharField("название новости", max_length=200)
    news_text = models.TextField("текст новости")
    pub_date = models.DateTimeField('дата публикации')

    def __str__(self):
        return self.news_title

    def wpr(self):
        return self.pub_date >= (timezone.now() - datetime.timedelta(days=30))



class Comment(models.Model):
    news = models.ForeignKey(News, on_delete=models.CASCADE)
    comment_author = models.CharField("Имя автора", max_length=50)
    comment_text = models.TextField("текст комментария")
    comment_date = models.DateTimeField('дата публикации')
    def __str__(self):
        return self.comment_author

вот мой код в админке:

from django.contrib import admin

from .models import News, Comment


admin.site.register(News, Comment)

Буду благодарен если поможете
