第一の方法

from rest_framework.views import APIView
class all_classroom(APIView):
    def get(self,request):
        classroom = Classroom.objects.all()
        ser = serailizers_classroom(classroom,many=True)
        return Response(ser.data,status=200)


class  single_classroom(APIView):
    def get(self,request,pk):
        classroom = Classroom.objects.get(pk=pk)
        ser = serailizers_classroom(classroom)
        return Response(ser.data,status=200)
    def put(self,request,pk):
        classroom = Classroom.objects.get(pk=pk)
        ser = serailizers_classroom(classroom,data=request.data)
        if ser.is_valid():
            ser.save()
            return Response(ser.data,status=200)
        return Response(ser.errors)
    def delete(self,request,pk):
        classroom = Classroom.objects.get(pk=pk)
        classroom.delete()
        return Response(status=200)

第2の方法

from rest_framework.generics import GenericAPIView
from rest_framework import mixins

    def get(self,request):
        return self.list(request)
    def post(self,request):
        return self.create(request)

class single_classroom(GenericAPIView,mixins.RetrieveModelMixin,mixins.DestroyModelMixin,mixins.UpdateModelMixin):
    queryset = Classroom.objects.all()
    serializer_class = serailizers_classroom
    def get(self,request,pk):
