Question

我用django构建了一个房地产管理系统。我想知道我的设计数据库是否错误，请让我知道对其进行改进

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    name = models.CharField(max_length=50)
    image = models.ImageField(upload_to='profiles', default='logo.png')
    phone = models.CharField(max_length=11, default='')
    bio = models.CharField(max_length=100, default='')
    city = models.CharField(max_length=20, default='erbil')
    location = models.CharField(max_length=40, default='')
    date = models.DateTimeField(default=datetime.now)
    active = models.BooleanField(default=False)

    def __str__(self):
        return f'{self.user}'


class Listing(models.Model):
    objects = ListingManager()

    company = models.ForeignKey(User, on_delete=models.CASCADE )
    title = models.CharField(max_length=200)
    slug = models.SlugField(unique=True, default='', blank=True)
    address = models.CharField(max_length=200)
    city = models.CharField(max_length=100, choices=city_choices, default='lodon')
    estate_type = models.CharField(max_length=20, choices=estate_choices, default=house)
    description = models.TextField(blank=True)
    rent_sale = models.CharField(max_length=20, choices=rent_sale_choice, default=sale)
    price = models.IntegerField()
    bedrooms = models.IntegerField(default=0)
    bathrooms = models.DecimalField(max_digits=2, decimal_places=1)
    garage = models.IntegerField(default=0)
    sqft = models.IntegerField()
    sold =  models.BooleanField(default=False)
    sold_time = models.DateTimeField(default=datetime.now,blank=True)
    photo_main = models.ImageField(upload_to='listings_main')
    photo_1 = models.ImageField(upload_to='listings_1', blank=True)
    photo_2 = models.ImageField(upload_to='listings_1', blank=True)
    photo_3 = models.ImageField(upload_to='listings_1', blank=True)
    photo_4 = models.ImageField(upload_to='listings_1', blank=True)
    photo_5 = models.ImageField(upload_to='listings_1', blank=True)
    photo_6 = models.ImageField(upload_to='listings_1', blank=True)
    is_published = models.BooleanField(default=True)
    list_date = models.DateTimeField(default=datetime.now, blank=True)
    unless = models.CharField(default='', max_length=20)

我应该更改代码吗？如果是，应该在哪里更改？或为两个以上的表（类）建立模型

对于模型中的时间戳记，请使用django utils TimeStampedModel

这些是我的建议：

对于https://github.com/stefanfoulis/django-phonenumber-field用于电话归档的电话，它将为您节省很多验证时间和时间

choices变量应按照Django文档的建议使用大写字母

对价格，卧室和任何有意义的模型使用PositiveIntegerField（）

为什么洗手间= models.DecimalField（）？
