similar to mod_perl – it embeds Python within Apache and loads Python code into memory when the server starts. Code stays in memory throughout the life of an Apache process, which leads to significant performance .queryset_only = False from_queryset() classmethod from_queryset(queryset_class) For advanced usage you might want both a custom Manager and a custom QuerySet. You can do that by calling Manager.from_queryset() names, which means you end up with a list of values, rather than a dict. At a small performance and memory cost, you can return results as a dict by using something like this: def dictfetchall(cursor):
