您可以重寫您的視圖perform_create()方法，如文檔中所述（您可能需要稍微滾動(dòng)一下，它位于“保存和刪除掛鉤”部分中：
class PostPlayer(generics.ListCreateAPIView):
? ? queryset = PlayerList.objects.all().order_by('-d_code')
? ? serializer_class = PlayerListSerializer
? ? def get(self, request, *args, **kwargs):
? ? ? ? d_code = request.data.get('h_code') + 'test'
? ? ? ? print(d_code)
? ? ...
? ? ...
? ? def perform_create(self, serializer):
? ? ? ? d_code = request.data.get('h_code') + 'test'
? ? ? ? #do something with d_code
? ? ? ? new_code = d_code + 'someSampleValue'
? ? ? ? serializer.save(d_code=new_code)
