1. 商品模組表結構分析

from django.db import models
from utils.MyBaseModel import Base
​
class Goods(Base):
  GOODS_TYPE = (
       ('1', 'Vip'),
       ('2', 'Course')
   )
  CHANNEL_TYPE = (
     ('1', '普通'), 
     ('2', '促銷')
   )
  course = models.ForeignKey('course.Course', on_delete=models.PROTECT)
  goods_type = models.CharField('商品種類', choices=GOODS_TYPE, max_length=8)
  product_id = models.CharField('產品id'， max_length=8)
  title = models.CharField('商品名稱', max_length=24)
  price = models.DecimalField('商品價格', max_digits=8, decimal_places=2)
  channel_type = models.CharField('購買渠道', choices=CHANNEL_TYPE, max_length)
  period = models.IntegerField('有效期', default=365)
  is_launched = models.BooleanField('是否上架', default=True)
  
  class Meta:
    db_table = 'tb_goods'
    
  def __str__(self):
    return self.title
  
class Orders(Base):
  PAY_METHOD = (
       (1, '支付寶')，
   )
  ORDER_STATUS = (
       (1, '待支付')，
      (2, '已支付')，
      (3, '已取消')，
   )
  user = models.ForeignKey('user.User', on_delete=models.PROTECT, verbose_name='下單使用者')
  goods = models.ForeignKey(Goods, on_delete=models.PROTECT)
  order_id = models.CharField('訂單號', max_length=24)
  trade_no = models.CharField('支付寶訂單號', max_length=32, null=True)
  pay_time = models.DateTimeField('支付時間', null=True)
  pay_method = models.CharField('支付方式', choices=PAY_METHOD, default=1,max_length=8)
  status = models.CharField('支付狀態', choices=ORDER_STATUS, default=1, max_length=8)
  total_amount = models.DecimalField(max_digits=10, decimal_places=2, verbose_name='商品總金額')
  
  class Meta:
    db_table = 'tb_orders'
    
  def __str__(self):
    return self.order_id
 

2. course/models.py中新增使用者購買課程

class UserCourse(Base):
  user = models.ForeignKey('user.User', on_delete=models.CASCADE, related_name='paycourse')
  course = models.ForeignKey('course.Course', on_delete=models.CASCADE, related_name='payuser')
  
  class Meta:
    db_table = 'tb_usercourse'
    
  def __str__(self):
    return "使用者：%s, 課程：%s" % (self.user.username, self.course.title)
 

3. user/models.py新增VIP表並新增使用者關聯

from django.db import models
from utils.MyBaseModel import Base
​
class Vip(Base):
  vip_choise = (
       ('0', '普通使用者'),
      ('1', '普通會員'),
      ('2', '高階會員'),
   )
  title = models.CharField('vip名稱', max_length=16)
  vip_type = models.CharField('Vip種類', choices=vip_choise, max_length=4)
  desc = models.CharField('vip描述', max_length=255)
  period = models.IntegerField('有效期', default=365)
  
  class Meta:
    db_table = 'tb_vip'
    
  def __str__(self):
    return self.title
  
class User(AbstractUser):
  phone = models.CharField('手機號', max_length=20)
  img = models.ImageField(upload_to='user', null=True)
  nick_name = models.CharField('暱稱', max_length=20)
  address = models.CharField('地址', max_length=255)
  
  vip = models.ForeignKey(Vip, on_delete=models.SET_NULL, default=None, null=True)
  vip_expiration = models.DateField('vip到期時間', blank=True, default=None, null=True)
  
  class Meta:
    db_table = 'tb_user'
    
 

3. admin.py中註冊

#goods/admin
from django.contrib import admin
from . import models
​
admin.site.register(models.Goods)
admin.site.register(models.Orders)
​
​
​
​
# user/admin
from django.contrib import admin
from user import models
​
admin.site.register(models.User)
admin.site.register(models.Vip)
​
