django 自带序列化组件效果

from django.core import serializers
def tt(request):
    data = request.GET
    data = dict(data)
    print(data)
    real_dict = {}
    for k, v in data.items():
        real_dict[k] = v[0]
    name = data["name"][0]
    id = data["id"][0]
    obj = FF(id=id,name=name)
    obj.save()

    obj = FF.objects.all()
    ret = serializers.serialize("json", obj)
    return HttpResponse(ret)
