Django GET ?q="parameter" in get_queryset Class Based View

Question

How do I access the "parameter" word in the url:

operations_product_search/?q=parameter

here:

class ASearchView(ListView):

...

def get_queryset(self, **kwargs):
    q = self.kwargs["q"]  <--- This is not working

Answer 1

It should be self.request.GET['q'].

Answer 2

I get query parameters using query_params

def get_queryset(self):
    q = self.request.query_params.get('q', None)
