Use constants from module in view

I have a constant.rb file in lib/ with:

module Constants   FOO = %w( tastes great)   BAR = %w( less filling) end

I'm able to access the constants fine in my Model, but I'm also using them to populate select boxes in a view and can't figure out how to make them available to the view.

I've tried:

require 'constants' class ApplicationController < ActionController::Base   include Constants   ....

end

as well as the same thing in the specific controller whose method is calling the offending action.

Any advice on where to require the module? Thanks,

Stu

It's not to do with requiring (you can get rid of that require 'constants') it's to do with where the module is included. You could just write Constants::FOO in your view.

Alternatively,

class ApplicationController < ActionController::Base   include Constants   helper Constants end

might work (but slightly abusing the helper method)

Thanks Fred, the syntax above works great.
