I have this app where if I am logged in as admin, I set the Group  
model so that when it saves a record it will automatically set  
the approved field to true. That field has a default value of false  
in mysql. This works fine in windows, but when I setup the app  
to run on [hostingrails.com](http://hostingrails.com) which is linux, it doesn’t work. Any  
ideas ?

=================================

class Admin::BaseController \< ApplicationController  
layout ‘admin’  
before\_filter :set\_admin, :authorize, :except =\>  
[“login”,“admin\_login”, ‘logout’]

…

def set\_admin  
Group.set\_admin()  
end

======================================

class Group \< ActiveRecord::Base

before\_create :set\_fields

def Group.set\_admin  
@@admin = true  
end

def set\_fields  
if defined? @@admin  
self.approved = true  
end  
end

end

end

I hope that you discovered that setting @@admin will never work in  
production when you have more than one user on your system… 🙂
