Question

I need to store app specific configuration in rails. But it has to be:

• reachable in any file (model, view, helpers and controllers
• environment specified (or not), that means each environment can overwrite the configs specified in environment.rb

I’ve tried to use environment.rb and put something like

USE_USER_APP = true 

that worked to me but when trying to overwrite it in a specific environment it wont work because production.rb, for instance, seems to be inside the Rails:Initializer.run block.

So, anyone?

I was helping a friend set up the solution mentioned by Ricardo yesterday. We hacked it a bit by loading the YAML file with something similar to this (going from memory here):

require 'ostruct' require 'yaml' require 'erb' #config = OpenStruct.new(YAML.load_file('#{RAILS_ROOT}/config/config.yml')) config = OpenStruct.new(YAML.load(ERB.new(File.read('#{RAILS_ROOT}/config/config.yml')).result)) env_config = config.send(RAILS_ENV) config.common.update(env_config) unless env_config.nil? ::AppConfig = OpenStruct.new(config.common) 

This allowed him to embed Ruby code in the config, like in Rhtml:

development:   path_to_something: <%= RAILS_ROOT %>/config/something.yml
