For anyone not familiar with http://dev.rubyonrails.org/ticket/6730, I will tell you a story…. (p.s.: ticket was set to invalid, but explains very well the problem I was having)
I had this beautiful class written in a file on the /lib directory of my rails directory. That class stored some data in class variable. Something like this:
# /lib/nice_class.rb class NiceClass mattr_accessor :value end
# /config/environment.rb NiceClass.value= "Hi there" # << NiceClass auto-loaded by rails
Ok what happened is that in first request, the value was right, and if I displayed that value in a view, it showed me the message. On second request, I loosed the message! That was because of rails loading the class in every request. That didn’t happened on production mode.
Solution: In the class file, I put:
# Avoid rails loading this file in every request (in dev mode) unless Dependencies.load_once_paths.include? __FILE__ Dependencies.load_once_paths << __FILE__ end

In development mode, all classes are auto-refreshed. This is design behavior so when you save a file you see the changes reflected immediately.

You can also do this in environment.rb:
config.to_prepare do
NiceClass.value= “Hi there”
end
