module Controller
# Adds an api to toggle features at controller level.
#
# Assume you have ransack enabled globally (Itsf::Backend.features?(:ransach) == true),
# but you can't use ransack in a specific controller, than you overwrite disabled_features
# in the controller and make it return an array with :ransack inside of it:
#
# def disabled_features
# [:ransack]
# end
#
# Then you can ask features?(:ransack) in the view and it will return false,
# although ransack is enabled globally.
#
module FeatureFlagsConcern
extend ActiveSupport::Concern
included do
helper_method :features?
end
private
# Ask featuers?(:foo) in the controller or your views to find out, if a
# feature is enabled in this controller.
def features?(what)
Itsf::Backend.features?(what) && !disabled_features.include?(what)
end
# overwrite this method, to disable features.
def disabled_features
[]
