from utils.mybasemodel import base
class goods(base):
goods_type = (
('1', 'vip'),
('2', 'course')
)channel_type = (
('1', '普通'),
('2', '**')
)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**', max_digits=8, decimal_places=2)
channel_type = models.charfield('購買渠道', 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) # 28位

verbose_name="商品總金額")
class meta:
db_table = 'tb_orders'
def __str__(self):
return self.order_id

1.2 course/models.py中新增使用者購買課程

class usercourse(base):

"""使用者購買的課程
"""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 "使用者:%s, 課程:%s" % (self.user.username, self.course.title)

1.3 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
# 建立vip表，並和使用者進行關聯
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('位址',max_length=255)
vip = models.foreignkey(vip, on_delete=models.set_null, default=none,
null=true)
