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!
