I am developing a Django application. For one of my class-based views, I want to use "generic.ListView" as a base class. This class assumes I will override "get_queryset()" method, which should prepare data for rendering in the HTML template. But to fetch this data from the database, I need to use the parameters taken from URL (GET parameters). In the same time, this method doesn't allow to pass parameters to it (only "self" object). How can I pass the needed parameter to this method?
