RailsAdmin is a Rails engine that provides an easy-to-use interface for managing your data

DeclarativePolicy::Base.enable_when

These next three methods are mainly called from PolicyDsl,
and are responsible for "inverting" the relationship between
an ability and a rule. We store in `ability_map` a map of
abilities to rules that affect them, together with a
symbol indicating :prevent or :enable.
