vue---07 支付和订单

为了方便开发，和以后项目的维护，我们再次创建子应用orders来完成接下来的订单和订单支付功能。

cd luffy/apps
python ../../manage.py startapp orders

注册子应用，settings/dev.py，代码：

INSTALLED_APPS = [
    # 子应用
    。。。
    
    'orders',
]

订单模型

from django.db import models

# Create your models here.
from luffy.utils.models import BaseModel
from users.models import User
from courses.models import Course
class Order(BaseModel):
    """订单记录"""
    status_choices = (
        (0, '未支付'),
        (1, '已支付'),
        (2, '已取消'),
        (3, '超时取消'),
    )
    pay_choices = (
        (0, '支付宝'),
        (1, '微信支付')
    )
    order_title = models.CharField(max_length=150,verbose_name="订单标题")
    total_price = models.DecimalField(max_digits=6, decimal_places=2, verbose_name="订单总价", default=0)
    real_price = models.DecimalField(max_digits=6, decimal_places=2, verbose_name="实付金额", default=0)
    order_number = models.CharField(max_length=64,verbose_name="订单号")
    order_status = models.SmallIntegerField(choices=status_choices, default=0, verbose_name="订单状态")
    pay_type = models.SmallIntegerField(choices=pay_choices, default=0, verbose_name="支付方式")
    use_coupon = models.BooleanField(default=False,verbose_name="是否使用优惠券")
    coupon = models.IntegerField(null=True, verbose_name="用户优惠券ID")
    order_desc = models.TextField(max_length=500, verbose_name="订单描述")
    pay_time = models.DateTimeField(null=True, verbose_name="支付时间")
    user = models.ForeignKey(User, related_name='user_orders', on_delete=models.DO_NOTHING,verbose_name="下单用户")

    class Meta:
        db_table="ly_order"
        verbose_name= "订单记录"
        verbose_name_plural= "订单记录"

    def __str__(self):
        return "%s,总价: %s,实付: %s" % (self.order_title, self.total_price, self.real_price)


class OrderDetail(BaseModel):
    """订单详情"""
    order = models.ForeignKey(Order, related_name='order_courses', on_delete=models.CASCADE, verbose_name="订单")
    course = models.ForeignKey(Course, related_name='course_orders', on_delete=models.CASCADE, verbose_name="课程")
    expire = models.IntegerField(default='-1', verbose_name="有效期周期")
    price = models.DecimalField(max_digits=6, decimal_places=2, verbose_name="课程原价")
    real_price = models.DecimalField(max_digits=6, decimal_places=2, verbose_name="课程实价")
    discount_name = models.CharField(max_length=120,default="",verbose_name="优惠活动类型")
    class Meta:
        db_table="ly_order_detail"
        verbose_name= "订单详情"
        verbose_name_plural= "订单详情"

把当前子应用注册到xadmin中

在当前子应用下创建adminx.py，代码：

import xadmin
from .models import Order
class OrderModelAdmin(object):
    """订单模型管理类"""
    pass

xadmin.site.register(Order, OrderModelAdmin)


from .models import OrderDetail
class OrderDetailModelAdmin(object):
    """订单详情模型管理类"""
    pass

xadmin.site.register(OrderDetail, OrderDetailModelAdmin)

 

后端实现生成订单的api接口
