Class: ActiveSupport::Deprecation::DeprecatedConstantProxy
- Defined in:
- lib/rubypitaya/app-template/vendor/bundle/ruby/3.1.0/gems/activesupport-7.0.4/lib/active_support/deprecation/proxy_wrappers.rb
Overview
DeprecatedConstantProxy transforms a constant into a deprecated one. It takes the names of an old (deprecated) constant and of a new constant (both in string form) and optionally a deprecator. The deprecator defaults to ActiveSupport::Deprecator
if none is specified. The deprecated constant now returns the value of the new one.
PLANETS = %w(mercury venus earth mars jupiter saturn uranus neptune pluto)
# (In a later update, the original implementation of `PLANETS` has been removed.)
PLANETS_POST_2006 = %w(mercury venus earth mars jupiter saturn uranus neptune)
PLANETS = ActiveSupport::Deprecation::DeprecatedConstantProxy.new('PLANETS', 'PLANETS_POST_2006')
PLANETS.map { |planet| planet.capitalize }
# => DEPRECATION WARNING: PLANETS is deprecated! Use PLANETS_POST_2006 instead.
