Does adding a class to models.py ever cause “view does not exist” error?

I was trying to implement a rating system that receives the information that a user submits.
But I was just wondering if it’s possible to have two classes in one models file and get Could not import myapp.comments.views.stars. View does not exist in module myapp.comments.views.

In my models file, I have

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()

By the way, stars is a html file. Any ideas?

This is my views,

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': ''})

My error message is simply,

Could not import myapp.comments.views.stars. View does not exist in module
myapp.comments.views.

My traceback is,
