Question

Using Rails 3.1.1. This is my YAML file in config/app_config.yml

development: &non_production_settings
  site_url: http://localhost:3000

This is my stripped config/application.rb

require File.expand_path('../boot', __FILE__)

# load app_config.yml  
require 'yaml'  
APP_CONFIG = YAML.load(File.read(File.expand_path('../app_config.yml', __FILE__)))

require 'rails/all'

I tried to put site_url in my template, even abort it, but it’s still returning nil:

<%= abort(APP_CONFIG[:site_url]) %> #returns: can't convert nil into String 

What have I done wrong? Thanks!

Answer 1

I have to move the code a bit and add an environment to it:

# config/application.rb
require File.expand_path('../boot', __FILE__)

require 'rails/all'

# load app_config.yml  
require 'yaml'  
APP_CONFIG = YAML.load(File.read(File.expand_path('../app_config.yml', __FILE__)))[Rails.env]

Then access the constant globally:

APP_CONFIG['site_url']
