如何重命名Django rest\u框架的search\u字段？

Question

我有

class ProductSearch(ListAPIView):
    queryset = Product.objects.all()
    permission_classes = [AllowAny]
    serializer_class = ProductSearchSerializer
    filter_backends = [SearchFilter]
    filter_fields = ['meta_data', 'store__district__id']

但当我通过api进行搜索时，我需要输入

"store__district__id": "blabla"

但我只想

"district_id": "x"

有人能帮忙吗？你知道吗

自定义搜索筛选器，如下所示：

from rest_framework import filters

class ProductSearchFilter(filters.SearchFilter):
    def get_search_fields(self, view, request):
        fields = super(CustomSearchFilter, self).get_search_fields(view, request)
        if 'district_id' in fields:
            fields['store__district__id'] = fields.pop('district_id')
        return fields

把它放在你的filter_backends里，把district_id放在视图的search_fields里：

class ProductSearch(ListAPIView):
    queryset = Product.objects.all()
    permission_classes = [AllowAny]
    serializer_class = ProductSearchSerializer
    filter_backends = [ProductSearchFilter]
    search_fields = ['meta_data', 'district_id']
