广告小程序后端开发（2.Models设计）

Posted 2021-11-25 xuepangzi

1.users的数据表设计：

 1.重建用户表：

1.在settings中配置：

AUTH_USER_MODEL=‘users.UserProfile‘

2.apps/users/models.py中建立UserProfile表：

class UserProfile(AbstractUser):
    """
    用户表
    """
    nickName=models.CharField(max_length=30,null=True,blank=True,verbose_name=‘微信名‘)
    avatarUrl = models.CharField(max_length=200, null=True, blank=True, verbose_name=‘用户头像URL‘)
    open_id = models.CharField(max_length=64, null=True, blank=True, verbose_name=‘OpenId‘)
    token = models.CharField(max_length=64, null=True, blank=True, verbose_name=‘token‘)
    gender = models.CharField(max_length=4, choices=((‘0‘, ‘未知‘), (‘1‘, ‘男‘), (‘2‘, ‘女‘)), default=‘0‘,
                              verbose_name=‘性别‘)
    city = models.CharField(max_length=20, null=True, blank=True, verbose_name=‘用户所在市‘)
    longitude = models.CharField(max_length=10, null=True, blank=True, verbose_name=‘经度‘)
    latitude = models.CharField(max_length=10, null=True, blank=True, verbose_name=‘纬度‘)
    jifen=models.IntegerField(default=0,verbose_name=‘积分‘)
    yongjin=models.FloatField(default=0,verbose_name=‘佣金‘)
    fensi_num=models.IntegerField(default=0,verbose_name=‘粉丝数‘)

    class Meta:
        verbose_name=‘用户‘
        verbose_name_plural = verbose_name

3.执行数据更新命令：

python manage.py makemigrations
python manage.py migrate

2.建立地区表：

1.在apps/users/models.py中建立地区表：

class Area(models.Model):
        """
        地区表
        """
        CATEGORY_TYPE = (
            (1, ‘省级‘),
            (2, ‘市级‘),
            (3, ‘区县级‘),
        )
        num=models.IntegerField(default=0,verbose_name=‘地区编码‘)
        name = models.CharField(default=‘‘, max_length=30, verbose_name=‘地名‘)
        category_type = models.IntegerField(choices=CATEGORY_TYPE, verbose_name=‘地区级别‘)
        parent_category = models.ForeignKey(‘self‘, null=True, blank=True, verbose_name=‘父类目录‘,
                                            related_name=‘sub_cat‘, on_delete=models.CASCADE)
        add_time = models.DateTimeField(default=datetime.now, verbose_name=‘添加时间‘)

        class Meta:
            verbose_name = ‘地区‘
            verbose_name_plural = verbose_name

        def __str__(self):
            return self.name

2.执行数据更新命令：

python manage.py makemigrations
python manage.py migrate

 2.ad的数据表设计：

1.安装处理图片的依赖包pillow：

pip install pillow

2.在apps/ad/models.py中：

from django.db import models
from datetime import datetime
from users.models import UserProfile,Area
from django.utils.safestring import mark_safe
# Create your models here.


class Category(models.Model):
    """
    分类表
    """
    name=models.CharField(default=‘‘,max_length=30,verbose_name=‘类别名‘)
    category_type=models.IntegerField(choices=((1, ‘一级类目‘),(2, ‘二级类目‘)),verbose_name=‘类别级别‘)
    parent_category=models.ForeignKey(‘self‘,null=True,blank=True,verbose_name=‘父类目录‘,related_name=‘sub_cat‘,on_delete=models.CASCADE)
    is_tab=models.BooleanField(default=False,verbose_name=‘是否导航‘,help_text=‘是否导航‘)

    add_time = models.DateTimeField(default=datetime.now, verbose_name=‘添加时间‘)

    class Meta:
        verbose_name = "发布广告或店铺"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.title

    def image_url(self):
        return mark_safe(‘<img src="/media/{0}" class="field_img">‘.format(self.image))

    image_url.short_description = ‘小程序码‘


class Prize(models.Model):
    """奖品"""
    title = models.CharField(max_length=15, null=True, blank=True, verbose_name=‘标题‘, help_text=‘最多15字‘)
    get_num=models.IntegerField(default=0,verbose_name=‘被领取数‘)
    price = models.IntegerField(default=0, verbose_name=‘所需积分‘)
    all_num=models.IntegerField(default=0,verbose_name=‘发布数‘)
    desc = models.TextField(default=‘‘, max_length=400, verbose_name=‘描述‘, help_text=‘最多400字‘)
    usage = models.TextField(default=‘‘, max_length=200, verbose_name=‘使用方式‘, help_text=‘最多200字‘)
    image = models.ImageField(max_length=200, default=‘‘, upload_to=‘prizeimg/‘, verbose_name=‘奖品图片‘)
    end_time = models.DateTimeField(default=datetime.now, verbose_name=‘过期时间‘)
    add_time = models.DateTimeField(default=datetime.now, verbose_name=‘添加时间‘)

    class Meta:
        verbose_name = "奖品"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.title

    def image_url(self):
        return mark_safe(‘<img src="/media/{0}" class="field_img">‘.format(self.image))

    image_url.short_description = ‘奖品图片‘


class Images(models.Model):
    """
    图片
    """
    is_banner=models.BooleanField(default=False,verbose_name=‘是否是轮播图‘)
    image = models.ImageField(max_length=200, upload_to=‘images/‘)
    good = models.ForeignKey(Good, verbose_name="广告或店铺",blank=True,null=True, on_delete=models.CASCADE)
    add_time = models.DateTimeField(default=datetime.now, verbose_name=‘添加时间‘)

    class Meta:

    def image_url(self):
        return mark_safe(‘<img src="/media/{0}" class="field_img">‘.format(self.image))

    image_url.short_description = ‘图片‘

    add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")

    class Meta:
        verbose_name = "提现记录表"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.user

2.执行数据更新命令：

python manage.py makemigrations
python manage.py migrate

3.其中“提现记录表”是暂时的，等到后期如果微信的“企业提款到零钱”功能可以开放使用，则要对这个表进行修改。
