如何从django过滤器集中的另一个过滤器获取值

Question

我有一个自定义的django过滤器，我希望得到＆＃34;距离＆＃34;在filter_location函数里面，我是如何实现这个的？

想要这样做的原因，我正在进行外部API调用以获取数据并同时需要这两个值。

class ListingFilter(django_filters.FilterSet):

    def filter_location(self, queryset, value):
        # Want to get the distance filter value here
        if value:
            #Location value


    def filter_distance(self, queryset, value):
        pass

    distance = django_filters.CharFilter(label='Distance', method=filter_distance)
    location = django_filters.CharFilter(label='Location', method=filter_location)

    class Meta:
        model = Company
        fields = ['distance', 'service', 'tags', 'location']


class CompanyListView(viewsets.ReadOnlyModelViewSet):
    queryset = Company.objects.all()
    filter_class = ListingFilter

一切都在self.data作为有序的词典：

class ListingFilter(django_filters.FilterSet):
    def filter_location(self, queryset, value):
        print(self.data['distance'])
        return queryset
