Rails - Oct 2005 - Global helper method?

I want a method to be accessible from everywhere in my app (it''s a
Gaussian
RNG) - I''ve already put them as protected methods in application.rb but
that
would only allow them to be accessed from controllers.

I have a method in a model that needs access to this too, and I''d
prefer not
performing the calculations outside the model. Copying the method definition
into the model violates DRY, but I don''t see any "helper"
files for models.
Is there some place to put this, or am I stuck putting it in a module and
requiring it everywhere? (require nexus_helpers?)

Thanks.

To make a method in a controller a helper method, use the helper_method, as in:

helper_method :some_method

Here is the api page:
http://rails.rubyonrails.com/classes/ActionController/Helpers/ClassMethods.html#M000109

This will only make it available in a controller and view though.

Perhaps you should create a library and stick it in the lib directory
if it must be in both controllers and models.
