Rails - May 2006 - Creating a new virtual field

Hello,

I have a problem with one of my Rails-Application, I have a table and on 
this there is object_name and a object_nr, so i want to create a 
combination of both in the model for a collection box.

I''ve tried something like this:


def set_new_object_name
  objects = find(:all).to_new_object_name
end

def self.to_new_object_name
  self.new_object_name = self.object_nr + " - " + self.object_name
end


I don''t know what to do know, can somebody help me?

Marius,

If I understand correctly what you''re trying to do, you want  
something like this in your model:

   def new_object_name
     "#{object_nr} - #{object_name}"
   end

Then in your controller:

   @objects = Object.find(:all)

And in your view:

   options_from_collection_for(@objects, ''id'',
''new_object_name'')
