path('/user/user.username:user/', view_profile) with Willem Van Onsem
summary
Argues that lazy model converters let path converters return proxies that defer DB queries or combine queries per database, concretely reducing roundtrips (demo shows one saved query when linking article and author) and preserving reverse URL generation; implements a management command and GitHub repo. Presents a regex-overlap checker that uses Greenery to compute intersections and flags unreachable or contained patterns, and cites admin pain with CharField PKs like "remove" or "history". URL overlap tool is work in progress.
