Where should Rails 3 custom validators be stored?

Question

I've seen docs/websites show that custom validators should go in a /lib or /lib/validators directory of a project. I've found (by reading an answer to another post) that they only seem to work in config/initializers. Does anyone know, or have a pointer to official documentation that shows where custom validators should live?

Answer 1

If you place your custom validators in app/validators they will be automatically loaded without needing to alter your config/application.rb file.
