django - 如何在 django-rest-framework APIView 中回滚事务？

Question

从下面看。我试图强制交易回滚。但是没有工作。数据仍然插入到数据库中。谁能给我正确的方法？

class DocumentDetailView(APIView):
        def post(self, request):
            sid = transaction.savepoint()
            serializer = DocumentSerializer(Documents(), data=request.data)
            if serializer.is_valid():
                serializer.save()
                transaction.savepoint_rollback(sid)
                return HttpResponse(JSONRenderer().render(serializer.data), status=201)
            else:
                return HttpResponse(JSONRenderer().render(serializer.errors), status=400)

Answer 1

尝试使用 transaction.atomic()

with transaction.atomic():
    serializer.save()
    transaction.set_rollback(True)
