Hi - I’m trying to see how my app behaves in production environment by  
running the development server with -e production:  
appdir~$ ./script/server -p production

my validations are in a file inside lib folder: [http://pastie.org/463883](http://pastie.org/463883)

Not so sure what I’m doing wrong, since all of that worked great while  
in development mode. I’d appreciate any help offered - thanks.

the above should obviously be ./script/server -e production  
that’s just a typo on my part.

still could use help 🙂

My blog post obviously wasn’t clear enough - I meant put your require  
inside an initializer in config/initializers

I read your post, which made sense. So, I moved all my requires into the  
initializer in the environment.rb file.

Rails then complained that it couldn’t find active record, so I added  
require ‘activerecord’, though it didn’t seem right (rails should know  
what that is). It then complained it doesn’t know what the downcase  
method (“Some string”.downcase) is, which seems pretty basic… so I’m  
not sure what I’m messing up.

# my file:

RAILS\_GEM\_VERSION = ‘2.3.2’ unless defined? RAILS\_GEM\_VERSION

require File.join(File.dirname( **FILE** ), ‘boot’)

Rails::Initializer.run do |config|

#… some default configs, like session, timezone

require ‘rubygems’  
require ‘activerecord’  
require ‘lib/custom\_validations’  
require ‘will\_paginate’

end
