如何编写条件是否通过查询Django过滤器检索数据

问题描述

我想写django过滤器通过在django rest框架中查询来检索数据的if else条件。我想通过过滤查询数据

class CreateRoutineFilter(filters.FilterSet):

    class Meta:
        model = CreateRoutine
        fields = ('batchCode','roomCode')

class CreateRoutineViewSet(viewsets.ModelViewSet):
    queryset = CreateRoutine.objects.all()
    serializer_class = CreateRoutineserializer
    filterset_class = CreateRoutineFilter
    filter_backends = (django_filters.rest_framework.DjangoFilterBackend,)
    __basic_fields = ( 'dpt_code','roomCode')
    filter_backends = (filters.DjangoFilterBackend,OrderingFilter)
    filter_fields = __basic_fields

   

 def retrieve(self,request,*args,**kwargs):
        params=kwargs
        print(params['pk'])
        # programs = Program.objects.all()
        if(coursesOffered = CourSEOffered.objects.filter(batchCode = params['pk']))
        else: 
        (coursesOffered = CourSEOffered.objects.filter(dpt_code = params['pk']))

        serializer = CourSEOfferedMiniSerializer(coursesOffered,many=True)
        return Response(serializer.data)
