Django DRF - 使用基本搜索过滤器进行多重 OR 搜索

Question

我正在尝试使用基本的 Django 过滤器进行多重 OR 搜索。我已经尝试了以下网址，但它们只有 return 第一个结果

api/circuit/?search=AB5814765;AB827451;AB0923784

使用逗号 returns 也没有结果。

是否有任何语法可以显示内置的多条记录或做一些定制需要做的事情，我尝试了一些定制尝试，但它们都失败了

当我尝试执行以下操作时，会出现 404

api/circuit/ref_search/AB5814765|AB827451|AB0923784

@action(detail=False, methods=['get'], url_path='ref_search/(?P<refs>[^/.]+)/', permission_classes=[IsAdminUser])
def ref_search(self, request, refs, *args, **kwargs):
    refs = refs.split('|')
    query = Q()
    for x in refs:
        q = Q(circuit__ref_no=x)
        query |= q
    queryset = DeviceCircuitSubnets.objects.filter(query)
    serializer = self.serializer_class(queryset, many=True)
    return Response(data=serializer.data)

我也试过了

api/circuit/ref=AB5814765|AB827451|AB0923784

def get_queryset(self):
    refs = self.request.query_params.get('ref', None)
    if refs is not None:
        refs = refs.split('|')
        query = Q()
        for x in refs:
            q = Q(status=x)
            query |= q
        queryset = queryset.filter(query)
    return queryset

我的看法：

class SiteCircuitDataROView(viewsets.ReadOnlyModelViewSet):
    queryset = Circuit.objects.all()
    serializer_class = CircuitSerializer
    permission_classes = (IsAdminUser,)
    filter_class = Circuit
    filter_backends = (filters.SearchFilter,)

Answer 1

您可以这样做，使用 __in 并调用 api/circuit/?refs=AB5814765|AB827451|AB0923784

class SiteCircuitDataROView(viewsets.ReadOnlyModelViewSet):
    queryset = Circuit.objects.all()
    serializer_class = CircuitSerializer
    permission_classes = (IsAdminUser,)
    filter_class = Circuit
    filter_backends = (filters.SearchFilter,)

    @action(detail=False, methods=['get'], url_path='ref_search/', permission_classes=[IsAdminUser])
    def ref_search(self, request, *args, **kwargs):
        refs = self.request.get('refs', '').split('|')
        queryset = DeviceCircuitSubnets.objects.filter(ref__in=refs)
        serializer = self.serializer_class(queryset, many=True)
        return Response(data=serializer.data)

Answer 2

像下面这样改变你的看法

class SiteCircuitDataROView(viewsets.ReadOnlyModelViewSet):
    serializer_class = CircuitSerializer
    permission_classes = (IsAdminUser,)

    def get_queryset(self):
        queryset = Circuit.objects.all()
        search = self.request.GET.get('search', '').split(',')
        if search:
           query = Q()
           for term in search:
               query = query | Q(circuit__ref_no__icontains=term)
           queryset = queryset.filter(query)
        return queryset

现在，像下面这样发送请求url

api/circuit/?search=AB5814765,AB827451,AB0923784
