Django的serializer序列化model
来自CloudWiki
视图层views_base
由于数据库中部分字段如img地址，日期时间等，不能序列化，因此对代码做如下改动
vi apps/goods/views_base.py ：
# -*- coding: utf-8 -*-
__author__ = 'bobby'
from django.views.generic.base import View
from goods.models import Goods
# from django.views.generic import ListView
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_list.append(json_dict)
# from django.forms.models import model_to_dict
# for good in goods:
# json_dict = model_to_dict(good)
# json_list.append(json_dict)
import json
from django.core import serializers
json_data = serializers.serialize('json', goods)
json_data = json.loads(json_data)
from django.http import HttpResponse, JsonResponse
return JsonResponse(json_data, safe=False)
