Question

我试图从输出json对象中删除pk和model作为Django序列化的一部分。我在views.py中尝试了以下代码，但它抛出了以下错误

TypeError: serialize() takes 2 positional arguments but 3 were given.

为了解决这个问题，我也使用了@staticmethod，但没有多大用处。

以下是 views.py

def get_stats(request):
    if request.method == "POST":
        srch_dropV = request.POST['srch_dropAJ']
    else:
        srch_dropV = ''
    if(srch_dropV == 'Lock'):
        stud = LockBased.objects.all()
    response_data = {}
    response_data['result'] = 'Success'
    serializer = NewSerializer()
    response_data['message'] = serializer.serialize('json', stud)
    return HttpResponse(JsonResponse(response_data), content_type="application/json")


from django.core.serializers.json import Serializer, DjangoJSONEncoder
import json

class NewSerializer(Serializer):
    def end_serialization(self):
        cleaned_objects = []

        for obj in self.objects:
            del obj['pk']
            del obj['model'] 
            cleaned_objects.append(obj)

        json.dump(cleaned_objects, self.stream, cls=DjangoJSONEncoder, **self.options)

请帮我确定问题并加以解决我正在使用Django 1.8和Python 3.4。

我认为您将var marker = [{43.000,-79.321},...]; var result = []; function test(){ for(var i=0; i<marker.length;i++){ result[i] =[]; for(var j=0; j<marker.length;j++){ drivingDistance(marker[i],marker[j],i,j,function(cb){ result[cb.i][cb.j] = cb.distance; }); } } } function drivingDistance(Point1,Point2,i,j,cb){ cb({distance:'something',i:i,j:j}); }与serializers.serialize()混为一谈：

serializer.serialize()

与模块级函数相比，序列化程序的方法不采用目标格式参数，而只采用查询集：

serializer = NewSerializer()
response_data['message'] = serializer.serialize('json', stud)

不能从django 1.8中的序列化器中排除pk和model
