I am able to render class based view generic ListView template using parameter hard coded in views.py.

class ResourceSearchView(generic.ListView):
 model = creations
 context_object_name = 'reviews'
 template_name = 'reviews.html'
 query = 'theory'

 # def get(self, request):
 # if request.GET.get('q'):
 # query = request.GET.get('q')
 # print(query)

 queryset = creations.objects.filter(narrative__contains=query).order_by('-post_date')

However, when parameter is sent via form by GET method (below),

class ResourceSearchView(generic.ListView):
 model = creations
 context_object_name = 'reviews'
 template_name = 'reviews.html'
 query = 'theory'

 def get(self, request):
 if request.GET.get('q'):
 query = request.GET.get('q')
 print(query)

 queryset = creations.objects.filter(narrative__contains=query).order_by('-post_date')

I receive this error

The view creations.views.ResourceSearchView didn't return an
HttpResponse object. It returned None instead.

Note that the parameter name q and associated value is being retrieved successfully (confirmed using print(query)).

  What's confusing you about the error? You've defined a get method with only half the functionality it needs; it gets a parameter, but then does nothing. Why are you defining get at all? What are you hoping to achieve?

So with CBV in Django, you have to return some kind of valid response that the interpreter can use to perform an actual HTTP action. Your GET method isn't returning anything and that's what is making Django angry. You can render a template or redirect the user to a view that renders a template but you must do something. One common pattern in CBV is to do something like:

return super().get(request, *args, **kwargs)

...which continues up the chain of method calls that ultimately renders a template or otherwise processes the response. You could also call render_to_response() directly yourself or if you're moving on from that view, redirect the user to get_success_url or similar.

Have a look here (http://ccbv.co.uk) for an easy-to-read layout of all the current Django CBVs and which methods / variables they support.
