The following line of code loads the data from config/config.yml file into a global CONFIG variable. The piece of code below is executed by the initializer initializers/load_config.rb.

CONFIG = File.open(RAILS_ROOT + "/config/config.yml") { |file| YAML::load(file) }

This works great for Rails 2.x.x. But in Rails3 it fails...

SOLUTION

This is what I did:

• Changed RAILS_ROOT to Rails.root (the new way in Rails3)
• Change the string concatenation

And this is the result code:

CONFIG = File.open("#{Rails.root}/config/config.yml") { |file| YAML::load(file) }

When using "+", the path was /config/config.yml. But then I placed the Rails.root inside the string with "#{}" and the path became /Users/jelle/Sites/fousa/config.config.yml.

Some things I just don't understand!

UPDATE

This is probably the best way to do this. It has been suggested to me by Jacques Crocker.

CONFIG = Rails.root.join("config", "config.yml").open{ |file| YAML::load(file) }
