I am a PHP developer that has done a lot of Ruby on Rails development over the last few years. There are a few gems I found especially useful again and again.
- drapergem/draper for decorating model instances
- collectiveidea/interactor for small service objects
- elabs/pundit for authorizing a user against a resource
