django过滤器获取视图内的过滤器字段值

问题描述

我有这样的过滤器

class SummaryFilter(django_filters.FilterSet):
start = django_filters.datefilter(
    field_name="date_modified",lookup_expr="gte",)
end = django_filters.datefilter(
    field_name="date_modified",lookup_expr="lte",)

在我看来，我正在这样做

class GetRiskyUseRSSummary(generics.ListAPIView):
   model = Summary
   queryset = Summary.objects.all()
   serializer_class = serializers.ModelSerializer
   filter_backends = (filters.DjangoFilterBackend,)
   filterset_class = SummaryFilter

def list(self,request,*args,**kwargs):
    queryset = self.filter_queryset(self.get_queryset())
    response = {}
    ********doing some stuff here and return in response*******
    **** for doing these i need the cleaned start and end date as date objects like below but Couldnt figure out the option for this in the library****
    self.filter.cleaned_data.get('start')
    self.filter.cleaned_data.get('end')
    
    return Response({"response": response})

如何在视图中获取这些数据？

解决方法

您可以通过初始化来检索过滤器数据

def list(self,request,*args,**kwargs):
    myfilter = self.filterset_class(request.GET,queryset=self.get_queryset())
    if myfilter.is_valid():
        queryset = myfilter.qs
        myfilter.form.cleaned_data.get('start')
        myfilter.form.cleaned_data.get('end')
