class StaffModelSerializer(serializers.ModelSerializer):
    status_text = serializers.CharField(source="get_status_display")

    class Meta:
        model = models.Staff
        fields = '__all__'


class StaffView(BaseView, ModelViewSet):
    queryset = models.Staff.objects.all()
    serializer_class = StaffModelSerializer
