Module: Charming::Controller::FocusManagement

Included in:
Charming::Controller
Defined in:
lib/charming/controller/focus_management.rb

Overview

Focus helpers mixed into Controller: lazily-allocated per-controller Focus object and predicates for ‘focused?(:slot)` checks from views. The Focus object is keyed by controller class name in the session, so it survives across controller dispatches for the same class.
