I Like My Params Like I Like My Coffee
summary
Migrating a large Rails codebase to Strong Parameters (gem for Rails 3/3.2) reveals concrete traps: a 1000+ line controller with deep nesting including additional_attributes_attributes breaks unless temporarily whitelisted with permit!; API tests return 400 where pre-Strong-Params gave 204; 55 PRs and 11 reverts track the work; a bug turns out to be Ruby hash ordering — order matters — fixed by moving timezone_name to the front; a helper gem strong_like_bull is created and sees 300+ downloads.
