[Nitro] Again me...

Sorry for all the bothering...

I would like to store in the DB an object of type Currency that I made. 
(Just a Float will not do, I need to convert from JPY, to USD, EUR, and so 
on, but also store the different type of number each time - once 
representing JPY with no decimal digits, the other time USD with 2 
decimal, etc etc). So I did the followin in the model.rb

class Currency < Float

   def initialize(value = 0.0, type = 'JPY', precission = 0)
     super
     @value, @type, @precission = value, type, precission
   end

   def jpy
   end

   def usd
   end

   def eur
   end
end

and then

class Project
   property   :locality,    String # domestic, foreign
   property   :state,       String # fixed, planned, under development
   property   :fee_per,     Float
   property   :fee,         Currency
   belongs_to :officer
   belongs_to :group
   belongs_to :company
   has_many   :loans
   has_many   :investments
   has_many   :reports
   has_one    Bgroup
end


But Og complains in   property   :fee,         Currency
with...
