django-rest-framework - DRF - 如何在 CreateAPIView 中获取创建的对象

Question

我的目标与 this question 中提出的问题非常相似。但从 DRF 的角度来看，而不是形式。

所以基本上问题是，如何在以下代码片段中获取新创建的对象:

TestSerializer(serializers.ModelSerializer)
    class Meta:
        fields = '__all__'
        model = TestModel


class TestView(generics.CreateAPIView):
    serializer_class = TestSerializer

    def create(self, request, *args, **kwargs):
        response = super(TestView, self).create(request, *args, **kwargs)
        created_model_instance = .... ?
        print(created_model_instance.id)
        return response

Answer 1

您可以覆盖 perform_create并使用 serializer.save获取创建的对象，例如:

class TestView(generics.CreateAPIView):
    serializer_class = TestSerializer

    def perform_create(self, serializer):
        """Some doc here!"""
        obj = serializer.save()
        print(obj.id)
