1.表结构分析

1.1 商品模块表结构分析

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', '促销')
    )
    course = models.ForeignKey('course.Course', on_delete=models.PROTECT)
    goods_type = models.CharField('商品种类', choices=GOODS_TYPE, max_length=8)
    product_id = models.CharField('产品id', max_length=8)
    title = models.CharField('商品名称', max_length=24)
    price = models.DecimalField('商品价格', max_digits=8, decimal_places=2)
    channel_type = models.CharField('购买渠道', choices=CHANNEL_TYPE,
    max_length=8)
    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, "支付宝"),
    )
    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="下单用户")
    goods = models.ForeignKey(Goods, on_delete=models.PROTECT)
    order_id = models.CharField('订单号', max_length=24)
    trade_no = models.CharField('支付宝订单号', max_length=32, null=True) # 28位
    pay_time = models.DateTimeField('支付时间', null=True)
    pay_method = models.CharField('支付方式', choices=PAY_METHOD, default=1,
    max_length=8)
    status = models.CharField('支付状态', choices=ORDER_STATUS, default=1,
    max_length=8)
    total_amount = models.DecimalField(max_digits=10, decimal_places=2,
    verbose_name="商品总金额")
	
	class Meta:
		db_table = 'tb_orders'
	def __str__(self):
		return self.order_id

1.2 course/models.py 中添加用户购买课程

class UserCourse(Base):
"""
用户购买的课程
"""
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 "用户:%s, 课程:%s" % (self.user.username, self.course.title)

1.3 user/models.py 添加VIP表并添加用户关联

from django.db import models
from utils.MyBaseModel import Base
# 创建Vip表，并和用户进行关联
class Vip(Base):
vip_choise = (
('0', '普通用户'),
('1', '普通会员'),
('2', '高级会员'),
)
title = models.CharField('vip名称', max_length=16)
vip_type = models.CharField('Vip种类',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('手机号',max_length=20)
    img = models.ImageField(upload_to='user',null=True)
    nick_name = models.CharField('昵称',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到期时间', blank=True, default=None,
null=True)
	class Meta:
		db_table = 'tb_user'
