장고 나머지 프레임 워크

나는 다음과 같은 전망을 - 가져 오기가 잘 작동하고 최대한 빨리처럼 그러나 '제독'데이터베이스에서 데이터를 당기고 장고 나머지 프레임 워크

class DeployResourceFilterView(generics.ListAPIView): 
    serializer_class = ResourceSerializer 

    def get(self, request, format=None): 
     resname = self.request.GET.get('name') 
     queryset = Resmst.objects.using('Admiral').filter(resmst_name=resname) 
     serializer = ResourceSerializer(queryset, many=True) 
     if queryset: 
      return Response(serializer.data) 
     else: 
      raise Http404 

    def post(self, request, format=None): 
     serializer = ResourceSerializer(data=request.DATA, many=True) 
     if serializer.is_valid(): 
      serializer.save(using='Admiral') 
      return Response(serializer.data, status=status.HTTP_201_CREATED) 
     return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

웹 페이지의 게시물은 '기본'데이터베이스에 저장하려고하기 때문에 테이블이 존재하지 않는다는 오류를 반환합니다. 특정 데이터베이스에 명시 적으로 저장하고 있기 때문에 왜이 작업을 수행하는지 잘 모르겠습니다. 여기에 흔적이 있습니다 -

여기서는 sqlite3 데이터베이스가 기본 데이터베이스임을 유의하겠습니다. 'Admiral'데이터베이스는 SQL Server 데이터베이스입니다. 그러므로 나는 using = 'Admiral'이 작동하지 않는다는 것을 안다.

라우터를 만들어이 문제를 해결해야했습니다. 이 'Admiral'db를 참조하는 특정 라우터를 만든 다음 API 'API'에 할당했습니다.
