Copyright (c) 2006 Daniel Owsianski (daniel-at-jarmark-d0t-org) Changes by Nate Walker 2008 (kiwinewt-at-gmail-d0t-com) Rails framework default configuration way is, as we all know, flexible and simple at the same time. Troubles begins when Your application starts to grow - some form of app specific configuration is then required to keep all as DRY as possible. AppConfig plugin provides a convenient way for configuration application wide settings. Extra custom files in config/ or other unusual configuration hacks are no longer needed. AppConfig extends Rails configuration process in a way that allows to setup application specific options within default configuration block. == Installation: You can install directly from the repository: $ script/plugin install git://github.com/kiwinewt/app_config.git Note: This plugin was originally obtained from: $ http://svn.jarmark.org/rails/app_config *NOTE*: because AppConfig modifies Rails configuration internals, must be included *before* Rails::Initializer#run. If You are using Rails v1.1+ this step is taken *automatically* during installation. Otherwise add the following line to conf/environment.rb file: require 'plugins/app_config/lib/configuration' (somewhere between line 'require File.join(File.dirname(__FILE__), 'boot') and 'Rails::Initializer.run') == Usage You can specify app-wide settings in configuration file(s) using 'app_config' prefix e.g. environment.rb: Rails::Initializer.run do |config| ... # --- My killer-app specific settings: config.app_config.my_key = 'my value' config.app_config.boot_time = Time.now config.app_config.default_mail_subject = '[appconfig] ' config.app_config.my_hash = {:a=>1, :b=>2} ... but also in e.g. environment/development.rb ... config.app_config.default_message = "I'm now in development mode..." ... Access to previously configured settings from within application code is also dead easy: AppConfig.my_key AppConfig[:my_key] AppConfig['my_key'] AppConfig.param('my_key') AppConfig.param(:my_key) AppConfig.param('my_key', 'value if my_key is nil') AppConfig.param(:my_key)do ... #executed when my_key is nil end safe parameter testing AppConfig.has_param?(:mail_from_address) AppConfig.has_param?('mail_from_address') Happy (re)configurations!
