向models.py添加一个类是否导致“视图不存在”错误？

我正在尝试实施一个评级系统，该系统接收用户提交的信息 . 但我只是想知道是否有可能在一个模型文件中有两个类并获得 Could not import myapp.comments.views.stars. View does not exist in module myapp.comments.views.

在我的模型文件中，我有

class CommentWithRating(Comment):
    rating = models.IntegerField()

    def save(self, *args, **kwargs):
        self.content_object.rating.add(score=self.rating, user=self.user, ip_address=self.ip_address)
        super(CommentWithRating, self).save(*args, **kwargs)

class Rating(models.Model):
    first_name = models.charField(maxlength=30)
    last_name = models.charField(maxlength=30)
    department = models.charField(maxlength=30)
    comment = models.charField(maxlength=10000)
    communi_rating = models.IntegerField()
    prepar_rating = models.IntegerField()
    interact_rating = models.IntegerField()
    help_rating = models.IntegerField()

顺便说一下，星星是一个html文件 . 有任何想法吗？

这是我的看法，

from django.shortcuts import render_to_response, render
from django.http import HttpResponse
from models import CommentWithRating
def stars(request):
    return render(request, 'star.html', {'score': ''})

我的错误信息很简单，

无法导入myapp.comments.views.stars . 模块myapp.comments.views中不存在视图 .

我的追溯是，
