每当我试着要运行python manage.py runserver命令

这是我的models.py：

from django.db import models 
from django.contrib import admin 

#------------------------------------------------------------------------------ 

class store(models.Model): 

    storeName = models.CharField(max_length=30)   # Store Name 


class coupon(models.Model):  

    couponDescription = models.TextField()    # Coupon Description 
    active = models.BooleanField(default=True) 
    couponCode = models.CharField(max_length=30) 
    couponStore = models.CharField(max_length=30)  # Store Name 
    featured = models.BooleanField(default=False) 
    couponTitle = models.CharField(max_length=100)  # Coupon Title 
    updatedAt = models.DateTimeField(auto_now=True) 
    createdAt = models.DateTimeField(auto_now=True) 
    lastTested = models.DateField(auto_now_add=True)  # When was the coupon last tested 
    localCouponId = models.CharField(max_length=30,primary_key=True) 


class commentCoupons(models.Model): 
    couponId = models.CharField(max_length=20)      # CouponId form couponRestApiApp 

    class Meta: 
     """Meta class to control display Behavior of the Model name """ 
     verbose_name_plural = "commentCoupons" 

    def __unicode__(self): 
     """Method to display string correctly""" 
     return unicode(self.couponId) 


class couponVotes(): 
    success = models.IntegerField()      # Count of the number of times people have made it work 
    failure = models.IntegerField()      # Count of the number of times this has failed  
    couponid = models.OneToOneField(commentCoupons) 

class comments(models.Model): 

    comment = models.TextField() 
    addedOn = models.DateField(auto_now=True) 
    userName = models.CharField(max_length=30) 
    commentCoupon = models.ForeignKey(commentCoupons) 

    class Meta: 
     """Meta class to control display Behavior of the Model name """ 
     verbose_name_plural = "comments" 

    def __unicode__(self): 
     """Method to display string correctly""" 
     return unicode(self.comment) 


class commentCouponsAdmin(admin.ModelAdmin): 
    list_display = ('couponId',) 

class commentsAdmin(admin.ModelAdmin): 
    list_display = ('comment','addedOn','userName','commentCoupon',) 

class couponAdmin(admin.ModelAdmin): 
    list_display = ('couponTitle','couponDescription','couponCode', 
        'couponStore','updatedAt', 
        'createdAt','localCouponId','active','featured') 

class couponVotesAdmin(admin.ModelAdmin): 
    list_display = ('success','failure',) 

admin.site.register(coupon,couponAdmin) 
admin.site.register(comments, commentsAdmin) 
admin.site.register(couponVotes, couponVotesAdmin) 
admin.site.register(commentCoupons,commentCouponsAdmin) 

#------------------------------------------------------------------------------ 

我不明白刚刚发生了什么，我只是增加了新的模型couponVotes和错误发生，但为什么？

您的班级couponVotes未继承models.Model。
