使用django-filters而不是model.objects.filter

Question

我的问题是如何在Django中使用django-filters进行以下查询？

Schedule.objects.filter(Q(room_id__number__icontains=get_request['room']) |  \
                                        Q(room_id__name__icontains=get_request['room']), \
                                        (Q(subject_id__full_name__icontains=get_request['subject']) |  \
                                        Q(subject_id__short_name__icontains=get_request['subject'])),
                                        (Q(teacher_id__name__icontains=get_request['teacher']) | \
                                        Q(teacher_id__short__icontains=get_request['teacher']))
                                   )

到目前为止我所拥有的内容如下。问题是这些字段没有room_id__name, teacher_id__short, subject_id__short_name。我只是想制作主题或请求，但不知道如何使用django-filters

class ScheduleFilter(django_filters.FilterSet):
    room = django_filters.CharFilter(name='room_id__number', lookup_type='icontains')
    subject = django_filters.CharFilter(name='subject_id__full_name', lookup_type='icontains')
    teacher = django_filters.CharFilter(name='teacher_id__number', lookup_type='icontains')

    class Meta: 
        model = Schedule
        fields = ['room', 'subject', 'teacher']
