Hunting for Treasure in Django
summary
Finds and demonstrates concrete utilities not broad concepts: cached_property stores a computed value on the instance so a heavy API call or aggregated queryset becomes one real computation when you list() it first time, import_string turns a dotted path into an actual callable or class and raises ImportError if wrong so configurable hooks validate, lazy and LazyObject defer instantiation enabling per-user S3 storage until first access, and RequestFactory builds real Django Request objects to unit test middleware and view logic without full client overhead
