Rails - Sep 2007 - Model field accessor missing? Driving me insane.

I did a simple migration...

class AddAdminDesignationToUsers < ActiveRecord::Migration
  def self.up
    add_column :users, :is_admin, :boolean
  end

  def self.down
    remove_column :users, :is_admin
  end
end


Now, if I go into the rails console, I can load a user from the DB and I
get correct results... u.is_admin? => false (or whatever).

But if I use ''is_admin?'' or ''is_admin'' in a
view or the controller
itself, I get an error: ''undefined method `is_admin?'' for
#<User:0x47750ac>''

Any ideas why? I''ve restarted the server (mogrel), and everything else
I
could
think of. Why would that work in the rails console (which uses the same
environment, etc) but not in the app itself?

I actually have them all pointing at the same database.  And I also 
tried running in development to test it out. Nothing.

Interestingly, the EXACT same app with the exact same migration is 
working on my development machine, in both development mode and 
production mode.

Perhaps you ran the migration and console in development mode, but your 
app is running in production mode so the migration never made it into the 
right database?

?
