Rails - Feb 2009 - Constants not visible in controllers or models

Hi,

I might be being a bit thick today but I have a problem that I can''t  
seem to shake.

I have some configuration data in a yaml file that I load with an  
initializer.

AVATARS_CONFIG = YAML.load_file("#{RAILS_ROOT}/config/avatars.yml")

The information includes where to save upload files and other stuff so  
it is needed in several places. One of the controllers can reference  
AVATARS_CONFIG, but the model, avatars.rb cannot. So I have to have  
the same line in any controller or model that needs it. Which looks to  
be very messy not to mention inconsistent - some places need it, other  
don''t.

I''ve tried to make them global, ie $AVATARS_CONFIG, but it
doesn''t
seem to work.

Anyone have any idea how I might get this and other constants I  
require to be available globally?

Thanks

Where have you defined those constants?

Constants should be accessed with NameOfTheClass::NAME_OF_THE_CONSTANT

Sorry, disregard everything I said. I''m having a blond moment. My  
initialiser scripts were actually .yml files rather than .rb files. So  
the line

AVATARS_CONFIG = YAML.load_file("#{RAILS_ROOT}/config/avatars.yml")

didn''t actually do anything. Didn''t error either but
it''s all my fault.

Sorry to waste your time
