Question

is it in get_queryset? if yes can you help me !?

Answer 1

You have access to the GET parameters (in the querystring ) with self.request.GET [Django-doc] .

So for example if there is a parameter ?category=foo , you can access foo with self.request.GET['category'] , or self.request.GET.get('category') if you want it to return None in case it is missing.

You thus can filter for example with:

from rest_framework import generics
from app.models import SomeModel
from app.serializers import SomeSerializer

class UserList(generics.ListAPIView):
    model = SomeModel

    def get_queryset(self):
        qs = super().get_queryset()
        category = .get('category')
        if category is None:
            return qs
        return qs.filter(category=categry)

Answer 2

just give pass the parameter with some default value:

def get_queryset(self, some_thing=default):
        .
        .
        .

It will work
