[Radiant] How to include classes in extensions?

[subsorama]

Hi,

I would like to access this snippet of code from within my extension  
tags:

class Numeric
   def ordinal
     cardinal = self.to_i.abs
     if (10...20).include?(cardinal) then
       cardinal.to_s << 'th'
     else
       cardinal.to_s << %w{th st nd rd th th th th th th}[cardinal % 10]
     end
   end
end

As the tags get called on the page I have tried adding the above to:

module StartDate::PageExtensions
   class Numeric < Page

     def ordinal
       cardinal = self.to_i.abs
       if (10...20).include?(cardinal) then
         cardinal.to_s << 'th'
       else
         cardinal.to_s << %w{th st nd rd th th th th th th}[cardinal %  
10]
       end
     end

   end
end

which is called from:

Page.send :include, StartDate::PageExtensions

The tag works fine when I don't call the new method, but when I do I'm  
getting an "undefined method 'ordinal' error", so I must be defining  
it wrong, but how do I do it right?

Any advice?


Thanks,

Dominic
