I’m almost always wanting to add configuration hooks to Rails engines when I build them. Up to this point I’ve never taken the time to figure out the most succinct way to provide configuration hooks. It turns out that it’s much simpler than I even imagined.
module MyGem class Engine < ::Rails::Engine isolate_namespace MyGem config.my_gem = ActiveSupport::OrderedOptions.new config.my_gem.some_setting = true end end
config directly in the class definition will expose the configuration in the consuming Rails application.
