Answer

You will have to directly pass request in context of the serializer as below.

SerializerClass(..., context={'request':request})

But if you use GenericAPIView, this behaviour is inherent and can access request directly in your serializer.

Add context in your serializer.

def get_replys(self, obj):
    queryset = StockUserComments.objects.filter(parent_id=obj.id).order_by('date')
    # Here
    serializer = StockUserCommentsOutputSerializer1(queryset, many=True, context=self.context)
    return serializer.data
