I just updated my rails application from 2.2.2 to 2.3.2 and the  
following message is displayed while trying to start with ./script/  
server:

```auto

I figured out that if I comment out “require ‘validators.rb’” inside  
my environment.rb than it’ll work fine. Validators.rb (http://  
[pastie.org/457289](http://pastie.org/457289)) handles some special validations and sits in my lib  
directory.

I am wondering what has changed from 2.2.2 to 2.3.2 that all the  
sudden this rather simple extension wouldn’t work anymore.

Does any have an idea?

My guess would be some change to the load order - you’d be better off  
loading your custom validations in an initializer, so that  
ActiveRecord is loaded.
