django评级以及一对一字段 models.py 怀疑

我该如何将食物和服务与餐厅模式结合起来，并对其进行评分，请帮助，提前感谢，而不是：

class Restaurant(models.Model):
    #fields here

class Food(models.Model):
    rating = RatingField(range=5, weight=5,can_change_vote = True,allow_delete = True,allow_anonymous = True)
    restaurant = models.OneToOneField(Restaurant)

class Service(models.Model):
    rating = RatingField(range=5, weight=5,can_change_vote = True,allow_delete = True,allow_anonymous = True)
    restaurant = models.OneToOneField(Restaurant)

尝试：

哦，谢谢，作为一名程序员，问这样的问题真是太愚蠢了，顺便说一句，谢谢

class Restaurant(models.Model):
    #fields here

class Food(models.Model):
    rating = RatingField(range=5, weight=5,can_change_vote = True,allow_delete = True,allow_anonymous = True)
    restaurant = models.OneToOneField(Restaurant)

class Service(models.Model):
    rating = RatingField(range=5, weight=5,can_change_vote = True,allow_delete = True,allow_anonymous = True)
    restaurant = models.OneToOneField(Restaurant)

class Restaurant(models.Model):
    #fields here
    food_rating = RatingField(range=5, weight=5,can_change_vote = True,allow_delete = True,allow_anonymous = True)
    service_rating = RatingField(range=5, weight=5,can_change_vote = True,allow_delete = True,allow_anonymous = True)
