18.4 查看订单
分析
- 查看订单的本质是查询并在页面展示订单数据，根据之前提交订单的设计可知，订单涉及到基本订单信息和商品订单信息两个部分，所以需要从两张表查询数据。
- 因是查询，所以采用get方法，将查询到的数据展示在user_center_order.html模板。
- 订单属于用户数据，所以在users应用中的views.py中定义视图类UserOrderInfoView，继承LoginRequiredMixin，保证登录状态，并在其get方法中实现查看功能。
实现
users应用中的views.py中定义视图类UserOrderInfoView
class UserOrderInfoView(LoginRequiredMixin, View):def get(self, request, page_num):"""提供我的订单页面"""user = request.user# 通过用户对象反向查询订单信息，[关联模型小写]_set是 Django 默认的反向关系管理器名称orders = user.orderinfo_set.all().order_by('-create_time')for order in orders:# 绑定订单状态order.status_name = OrderInfo.ORDER_STATUS_CHOICES[order.status - 1][1]# 绑定支付状态order.pay_method_name = OrderInfo.PAY_METHOD_CHOICES[order.pay_method - 1][1]order.sku_list = []# 正向查询订单商品order_goods = order.skus.all()for order_good in order_goods:sku = order_good.skusku.count = order_good.countsku.amount = sku.price * sku.countorder.sku_list.append(sku)# 分页处理page_num = int(page_num)try:paginator = Paginator(orders, constants.ORDERS_LIST_LIMIT)page_orders = paginator.page(page_num)total_page = paginator.num_pagesexcept EmptyPage as e:return HttpResponseNotFound('订单不存在')context = {'page_orders': page_orders,'total_page': total_page,'page_num': page_num,}return render(request, 'user_center_order.html', context)
在users应用的urls.py中增加路由
path('orders/info/<int:page_num>/', views.UserOrderInfoView.as_view(), name='myorderinfo'),
user_center_order.html

最后，将其它模板中注释掉的查看订单的语句释放掉，即可看到查询订单的效果。
