Hi,

I just build my own class that looks like this


   class Rechnungsdaten
     attr_accessor :nummer
   end


I saved this file as "rechnungsdaten.rb" in the models folder.
When I use this code:


   @rechnung = Rechnungsdaten.new
   @rechnung.nummer = @rechnungsnummer


I get this error message in my browser:


   undefined method `nummer=' for #<Rechnungsdaten:0x3976148>


How could this be? I can't understand that! Or do I have to include the 
class by using requieres? .... But why doesn't rails say me that it 
can't find >> Rechnungsdaten <<?
