前后端分离电商，业务逻辑部份

Posted 2021-01-19 fgxwan

先说一下传统的前后端分离，，

class GoodsListView(View):
    def get(self, request):
        """
        通过django的view实现商品列表页
        :param request:
        :return:
        """
        json_list = []
        goods = Goods.objects.all()[:10]
        for good in goods:
            json_dict = {}
            json_dict["name"] = good.name
            json_dict["category"] = good.category.name
            json_dict["market_price"] = good.market_price
            json_dict["add_time"] = good.add_time
            json_list.append(json_dict)       
#导入HttpResponse, JsonResponse 模块
#导入json 
import json
from django.http import HttpResponse, JsonResponse
return HttpResponse(json.dumps(json_list),content_type="application")


      

View Code

配置一下访问路由，先导入相应视图

 

浏览器安装json,vive

 

痛点：

   不能对tim序例化，填充对象，类似于下面的步聚太多，容易出错

json_dict["category"] = good.category.name
json_dict["market_price"] = good.market_price
json_dict["add_time"] = good.add_time

所以下面我们使用
