I’ve written a custom validation ah la advanced rails recipes. When i’m  
in development everything works great. As soon as I “script/server -e  
production”  
then my console gets lit up with errors [http://www.pastie.org/361177](http://www.pastie.org/361177)

I played around with what actions cause this, and apparently putting

validates\_anything\_not\_standard :anything

causes an error.

This includes having the validation in my model, or loaded in a  
lib/file.rb . This also includes having no validation code, and just  
placing “validates\_anything\_not\_standard :anything” call in my model.  
I’ve seen a few other posts about similar problems, but nothing  
conclusive. Why would this happen only when in the production  
environment, and not in development?

Rails 2.2.2, Ruby 1.8.6, Will-Paginate 2.3.6.

My hunch would be because of

You were right.

When i turned of config.cache\_classes in my environments/production.rb  
everything worked great. Of course I cant run a deployment like that,  
sooo…i moved my " require ‘custom\_validations’ " into my model  
right above my validation call, to ensure it gets loaded in the right  
order. I’m not sure how kosher this is, but it fixed the problem.

models/phrase.rb:  
…  
require 'custom\_validations  
validates\_not\_spam :word  
…

Personally my preferred solution is what is outline in the blog post:  
have an initializer that requires stuff like that’

Guess i’m just dense, that worked great too. I had never used  
initalizers/ before except to regulate inflections, just created an  
Application.rb and threw in my

require ‘custom\_validations’

Thanks Fred!!
