title: How to add parameters to get_queryset in Django Rest Framework using Swaager?
body: <p>I have a class based view which inherits the <code>ModelViewSet</code> from <code>django-viewsets</code>. I have been able to add query parameters to all other functions except the <code>get_queryset</code> function. I have used <code>manual_parameters</code> with <code>@swagger_auto_schema</code>. Here is the code prototype:</p>
  <pre><code>class YetAnotherObjectView(viewsets.ModelViewSet, views.APIView):
  
  ...
  custom_param = openapi.Parameter('custom', openapi.IN_QUERY, description = &quot;Valid description &quot;, type= openapi.TYPE_STRING)
  
  @swagger_auto_schema(manual_parameters = [custom_param])
  def get_queryset(self):
      ...
  # the parameters are not being displayed on Swagger
  
  @swagger_auto_schema(manual_parameters = [custom_param])
  def retreive(self, request, *args, **kwargs):
      ... 
  # the parameters are displayed in swagger
  
  </code></pre>
  <p>What could be the solution to this?</p>
