Flarg

Adds a class to your ralis app that stores configuration variables.

WTF?

Isn't there a Rails.application.config?

Yes, and this gem uses it so you can do:

# config/initializers/some_initializer.rb

MyKeenAppConfig.configure do |config|

  config.use_recursive_sql = Rails.application.config.database_configuration[Rails.env]["adapter"] == "postgresql"

end

Then in your app somewhere:

class Thing < ActiveRecord::Base

  def ancestors
    if MyKeenAppConfig.config.use_recursive_sql
      self.class.find_by_sql(%Q^ WITH RECURSIVE parents AS ( SELECT .... )^)
    else
      Rails.logger.debug("Recursive SQL not supported by this database")
    end
  end

Flarg namespaces keys in Rails.application.config so you don't have to!
