在Django的视图函数中，我们从数据库中获取数据，由以下几种方式将其序列化成JSON数据：
class PublishView(View): def get(self, request): publish_list = list(Publish.objects.all().values()) return HttpResponse(json.dumps(publish_list))
通过list强转的方式。
class PublishView(View): def get(self, request): publish_list = Publish.objects.all() temp = [] for obj in publish_list: temp.append({ ‘id‘: obj.id, ‘name‘: obj.name, ‘email‘: obj.email }) return HttpResponse(json.dumps(temp))
通过字段拼接的方式。
使用model_to_dict方法来将对象转换成字典：
class PublishView(View): def get(self, request): from django.forms.models import model_to_dict publish_list = Publish.objects.all() temp = [] for obj in publish_list: temp.append(model_to_dict(obj)) return HttpResponse(json.dumps(temp))
利用django中的序列化组件：·
class PublishView(View): def get(self, request): from django.core import serializers publish_list = Publish.objects.all() ret = serializers.serialize("json", publish_list) return HttpResponse(ret)
4.方式四
利用restframework中的serializer：
from rest_framework import serializers class PublishSerializers(serializers.Serializer): name = serializers.CharField() email = serializers.EmailField() class PublishView(View): def get(self, request): publish_list = Publish.objects.all() ps = PublishSerializers(publish_list, many=True) return HttpResponse(ps.data)
这种方式的前提是安装djangorestframework。
pip install djangorestframework
